Chocolate Oreo Bundt Cake with Vanilla Cream Icing

Embark on a chocolate cookies 'n cream dessert adventure with this towering, fun Oreo pound cake baked in a bundt pan!

This dramatic black and white pound cake combines the deep midnight intensity of black cocoa powder, bloomed in milk and mixed with sour cream for an extra moist, tender cake crumb. But here's the twist – hidden inside is a layer of whole Oreo cookies, adding an unexpected crunch to every bite.

To top it all off, this Oreo bundt cake is finished with a thick vanilla icing and crowned with even more crushed Oreos. Because decorating cakes doesn't have to be hard!

This Oreo pound cake is truly excellent on its own, but it's even better served with a scoop of cookies n' cream ice cream or a cold glass of milk to wash it down.

About This Recipe

This black cocoa bundt cake is a riff on my classic chocolate pound cake recipe, which bakes in a loaf pan and has a simple powdered sugar topping.

I scaled that recipe up to fill a 10-cup bundt pan and subbed a majority of the natural unsweetened cocoa powder for black cocoa powder, aka the cocoa powder used in Oreo cookies.

Black cocoa has an intense yet mellow chocolate flavor, so I didn't replace all of the regular unsweetened cocoa powder in the recipe. The black cocoa brings the intensity, while the unsweetened cocoa powder serves up an undeniably rich chocolate flavor without being overly sweet.

Black cocoa powder is an ultra dutch processed cocoa powder which has a higher fat content than unsweetened cocoa powder, adding even more moisture to this chocolate cake.

I tested a few different ways to mix Oreo cookies into this Oreo bundt cake, but ultimately settled on a hidden ring of cookies around the middle. It's such a dramatic visual when you cut a slice of cake and see that crisp, clean white line of Oreo cookie filling!

If you really want to up the amount of Oreos in the cake, you can certainly do two or even three layers of cookies inside!

Ingredient Notes

Here are the ingredients that you'll need to make this Oreo bundt cake recipe! See recipe card for quantities.

• Unsalted Butter - This recipe uses unsalted American-style butter (e.g. not European butter like Kerrygold). If using a salted butter, cut the amount of salt in the recipe in half. You'll also need about a tablespoon of butter for the Oreo cream icing drizzle.
• Sugar - Plain old regular granulated white sugar. Nothing fancy here!
• Brown sugar - I use dark brown sugar which has more molasses in it for extra flavor and moisture, but light brown sugar will also work.
• Eggs - This recipe uses large eggs, which weigh about 48 grams per egg. If you use another size egg, this will affect the outcome of the cake!
• Whole Milk - For blooming the cocoa powder. The fat in whole milk adds a lot of moisture to this cake. Skim or low-fat milk will give you a much drier cake. You'll also need whole milk to make the icing; skim or low-fat milk will make the icing watery.
• Black Cocoa Powder - Black cocoa powder is CRUCIAL for making anything taste like Oreos and give it that deep midnight black color. Black cocoa powder is not the same as dark cocoa powder. While you can use other cocoa powders in this recipe, for true Oreo flavor, you need a true black cocoa powder. If your grocery store doesn't have it in stock (and it's likely they don't), I recommend King Arthur Baking's Black Cocoa Powder which you can order online.
• Unsweetened Cocoa Powder - This recipe uses a small amount of unsweetened natural cocoa powder like the classic box of Hershey's you can find in most grocery stores. This adds a bit of sweeter chocolate flavor to balance out the intensity of the black cocoa powder.
• Vanilla - I usually use vanilla bean paste because it has a more intense vanilla flavor, but regular vanilla extract will work just fine here too.
• Sour Cream - Full fat sour cream works best — you really need the fat content to make the chocolate cake tender and moist. You won't get the same results with low fat options.
• Flour - Regular all purpose flour. Gluten free cup-for-cup all purpose flours should also work, but I haven't personally tested them.
• Salt - I use Diamond Crystal Kosher Salt which half as salty as other brands. If measuring by weight, it doesn't matter what brand of salt you use. But if you're measuring by volume and using a different brand of salt, even a different brand of kosher salt, cut the amount of salt in half.
• Baking Powder - This helps the cake rise. The air whipped into the butter by the sugar will provide a lot of the cake's rise, but since we're adding quite a bit of liquids and fats to this cake, adding baking powder will help ensure the cake rises nicely in the oven.
• Powdered Sugar - Also called "confectioner's sugar" this is needed only for making the Oreo vanilla cream icing that goes on top of the cake.
• Oreo Cookies - I'm partial to the "Double Stuf" Oreo cookies, but you can use regular Oreos, "Mega Stuf" Oreos, or generic brand chocolate sandwich cookies here too! You can even use fun flavored Oreo cookies if you want!

• Bring the butter to room temperature. Let the butter sit out at room temperature (70°F) for an hour or two prior to baking. If you're short on time, microwave the wrapped sticks of cold butter for about 4 seconds per side. The butter should still feel slightly cool to the touch but and soft enough to press a finger into, but not so soft that it's greasy or melty — an internal temperature of 65°F.
• Bring the eggs to room temperature. Submerge the eggs in hot water for about 10-15 minutes. Cold eggs will cool down the butter, causing the batter to break and separate, making it harder for the cake to rise.
• Mix the dry ingredients together (NOT including cocoa powder and sugar). Whisk the flour, baking powder, and salt together in a bowl. I like using a tall 32 oz deli container because it's easier to pour from.
• Sift the cocoa powders. I wouldn't tell you to sift something if it wasn't important. Cocoa powder is naturally very lumpy and if you don't sift it, those lumps will end up in your final cake no matter how much you whisk them. Sift. The. Cocoa. Powders.

Bloom the Cocoa Powder

Blooming the cocoa powders helps intensify the chocolate flavor. It's a simple but super important step in this Oreo bundt cake recipe, since black cocoa has a relatively mild chocolate flavor. We want it to be at its best!

To scald milk, swirl the milk in the pot over low-medium heat until small bubbles form around the edges; when you tilt the pan you should see lots of tiny active bubbles on the bottom of the pot.

Do this step first so the bloomed chocolate mixture can cool slightly — you don't want the heat to scramble the eggs or melt the butter in the cake batter!

Instructions - Black Cocoa Cake Batter

Since this is basically the same cake batter process as I used in my chocolate pound cake recipe, I'm going to keep this part brief. I recommend popping over to that recipe post to read more about it and see the visual step-by-step in detail! (I've also got some ingredient substitutions in that post, in case you need them.)

When it comes to aerating the butter and sugars together, it can take 3-5 minutes, sometimes even 7 minutes for the butter and sugar to reach the right texture, depending on how soft the butter was at the start.

Scrape down then bowl, then add the eggs one at a time, beating for about 45-60 seconds after each one to give them time to fully incorporate. Scrape down the bowl and beater before adding the next egg.

Finally, on lowest speed, alternate adding the dry ingredients (the flour, baking powder, and salt) and the wet ingredients (the bloomed cocoa mixture). Start with the flour and end with the flour.

It's not as complicated as it sounds. You're basically adding flour --> chocolate --> flour --> chocolate --> flour. Mix on the lowest speed, stop when they're just barely combined, and pause between additions to scrape down the bowl and beater as needed.

Alternating adding the dry and wet ingredients on low speed and pausing to scrape down the bowl between additions is super important to help prevent over mixing.

Over mixing encourages the flour to begin forming a strong gluten network which will make the cake dense and tough.

When the last batch of dry ingredients has been added and just a few streaks of flour in the batter and the walls of the bowl remain, switch to a spatula to finish mixing.

This also helps you avoid over mixing your cake batter so it stays nice and tender when it bakes. Scrape to the very bottom of the bowl to make sure there's nothing hiding that still needs to be mixed in.

You'll end up with a luscious, glossy dark brown chocolate cake batter that has a silky texture almost like a thick brownie batter. It's honestly one of the most beautiful cake batters I've ever made.

Baking in a Bundt Pan

Get the non-stick spray on all the walls and nooks and crannies of the bundt pan and up the column in the middle.

At the same time, you don't want the non-stick spray pooling at the bottom of the bundt pan. A little bit is fine, but if you have a lot collecting at the bottom, use a paper towel to gently dab some of the excess away.

Scoop the rest of the chocolate cake batter into the pan and even it out again. This step is crucial for ensuring your Oreo bundt cake isn't lopsided when it comes out of the pan.

The cake batter doesn't need a perfectly flat surface, you just want to make sure it's distributed evenly all the way around the pan.

Also, honestly? Swirling the cake batter around to even it out and make sure that it's pressed into all the funky scalloped edges of the bundt pan is just really fun.

Bake the Oreo bundt cake at 350°F for 60-65 minutes, until a toothpick or small knife inserted into the center comes out with just a few crumbs (not wet batter) clinging to it.

Checking For Doneness: It's hard to tell when a chocolate cake is done because you can't see any browning. Checking for a few crumbs on the cake tester is the best way to know. If you're using an instant read thermometer, you're looking for a temperature of 190°-200°F.

Even with all the sour cream and milk we've added to this black cocoa cake for extra moisture, you really don't want to over bake it or it will come out dry.

Some carryover cooking will happen as the cake rests in the pan after it comes out of the oven, so err on the side of pulling it a couple minutes too soon if you're not sure.

If you don't have oven mitts you trust, place a kitchen towel under the bundt pan and pull the ends taught at the sides of the cooling rack so the towel holds the pan in place as you flip it.

If the cake doesn't come out of the cake pan on the first try, flip it back over and drape a lightly damp towel over the mouth of the pan. The steam should help it release from the pan.

Let the Oreo bundt cake cool completely on the rack before icing. If the cake is even slightly warm, the icing will melt right off, so give your cake plenty of time to cool!

The bottom of the cake will always be slightly curved, but as the warm cake cools, gravity will pull it down and flatten out the bottom slightly.

Vanilla Cream Oreo Bundt Cake Icing

To make the Oreo cake icing, start by sifting the powdered sugar (again, you can't whisk out lumps and clumps no matter how hard you try). Then whisk in 1 tablespoon melted butter, 1 teaspoon vanilla extract, and 4 teaspoons whole milk.

Depending on the brand of powdered sugar you have, what type of milk you're using (on the honor system, I'm assuming you're using whole milk as instructed), and how precisely you measured the butter and vanilla, the amount of milk you need can change dramatically.

After the initial 2 teaspoons of milk, add the milk 1 teaspoon or ½ teaspoon at a time, whisking it in well before adding more.

You're looking for a fairly thick icing. It shouldn't be runny, and it should move slowly in the bowl. If you lift the whisk up, it will very slowly drip off and may not even drip all the way back into the bowl.

If the icing is too runny or wet, whisk in more powdered sugar 1 tablespoon at a time until it thickens up.

The melted butter will help the icing firm up as it cools, giving it that Oreo creme-like consistency.

At first, the icing will look light brown due to the vanilla extract, but it will be white once it dries.

Transfer the icing into a piping bag (or a plastic bag with the corner snipped off) and pipe a thick zig-zag around the top of the cake.

Focus more on getting the icing to drip down the outside of the cake in the grooves of the fluted bundt pan pattern so you don't waste a lot pooling in the middle.

NOTE: The chocolate bundt cake must be completely cool before you add the Oreo icing or it will melt off of the cake.

Before the icing dries, top it with chopped Oreo pieces so that they stick in place. Voila! That's your Oreo bundt cake, done.

Suggested Equipment

Here's the equipment I use to make this chocolate Oreo pound cake in a bundt pan. You don't need to have all of these same tools, but they may make the process easier!

• Kitchen Scale - You need a kitchen scale to measure your ingredients for this cake. Measuring flour and powdered sugar by cups can throw the recipe off a lot, as they're very inaccurate depending on how tightly you pack them into the cup when you scoop it and also what brand of measuring cups you're using.
• Electric Mixer - I use a KitchenAid stand mixer with the paddle attachment. An electric hand mixer will also work — the creaming stage may just take a little longer.
• Bundt Pan - This recipe is designed for a 10 cup bundt pan. A larger bundt pan will also work. For best results, I recommend using a non-stick bundt pan from a reputable brand like Nordic Ware or USA Pan.
• Mini Offset Spatula - For smoothing out the cake batter in the pan. Trust me, you'll think a regular spatula or a knife can do the same job, but once you try using a mini offset spatula, there's no going back.
• Wire Cooling Rack - A wire cooling rack will help the cake cool faster so you can ice it sooner. Icing the cake while it's on a cooling rack inside a sheet pan will also allow any excess icing to drip off without pooling around the bottom of the cake.
• Whisk - You'll want to use one of your favorite whisks to make the Oreo icing drizzle. If you don't have a whisk, a fork is the next best tool for the job.
• Small Sauce Pot - You'll need a 2-3 cup sauce pot to scald the milk. A larger pot will work, but the milk will warm up a lot faster so keep an eye on it.

Storage Notes & Freezing

This Oreo pound cake can be stored at room temperature in an airtight container for 4-5 days. You can also refrigerate it in an airtight container for up to 2 weeks.

The chopped Oreos on top will begin to go stale and absorb some moisture from the icing after about 24 hours.

The cake can be made up to 3 days in advance. Wait to put the icing and chopped Oreos on until the day you plan to serve it.

The cake can be frozen, icing and all, for up to 3 months. To freeze, cut the cake into quarters and wrap well in plastic wrap, then place inside a large plastic bag. Defrost in the fridge before serving.

Practical Tips and Recipe Notes

• For Oreo cookies mixed into the dough instead of just in the middle, cut the cookies into halves or quarters and stir them in when you finish mixing the cake batter by hand. If you cut the cookies too much smaller than that, they will melt and blend into the cake when it bakes and you won't really notice they're there at all.
• If the cake mixture begins to look split or curdled as you're adding the eggs, don't sweat it too much. It will come back together when you add the flour.
• When in doubt, SCRAPE DOWN THE BOWL. If it feels like you're stopping too often to scrape down the bowl, that means you're doing it right. You don't want any ingredients to go unincorporated or you'll end up with large air bubbles or clumps in your final cake.
• Mixing the dry ingredients on the lowest possible speed and stopping as soon as they're all combined is super important. The goal is to avoid developing gluten in the cake batter, which would make your old fashioned vanilla pound cake dense and tough, with lots of trapped tunnels of air bubbles inside.
• Make sure your baking powder is fresh! If you aren't sure, it's probably not. Baking powder is good for about 6 months, after that it loses its potency. To check if it's still good, Epicurious recommends mixing 1 cup very hot tap water with 2 teaspoons baking powder: "If there’s an immediate fizzing reaction that dissipates all of the powder, you’ll know it still works. If there’s no bubbling, the baking powder is no longer potent and needs to be swapped out."
• When adding icing to this bundt cake, you'll want to have the cake either on a cooling rack so any excess icing can drip through, or place it on a cake board, or whatever platter you plan to serve it on so the drips can be part of the overall look. Once you add the icing, you definitely don't want to be moving the cake around too much!

Why Temperatures Matter

Pay attention to the temperature directions in this chocolate pound cake recipe as they can dramatically affect the way your cake turns out.

• If your butter is too warm, it won't be able to incorporate enough air. If the butter is too cold, it will take much longer to cream properly.
• If you use cold eggs, they will cause the butter to firm up in the mixer and you risk it curdling or splitting, resulting in a flat, tough cake.
• If your oven runs hot or runs cold, this can affect the cake's rise, the thickness of the crust, the moisture, the texture, and the baking time. I recommend using an oven thermometer to make sure you're baking it at the right temperature!
