Moist Chocolate Pound Cake in a Loaf Pan

Today I'm spilling the cocoa beans on my all-time favorite classic chocolate pound cake recipe. It's velvety, moist, and decadent, with simple ingredients like unsweetened cocoa powder, whole milk, brown sugar, and sour cream (!!!) for extra tenderness.

It bakes in a standard sized loaf pan and the chocolate flavor is so rich and dreamy there's no frosting needed — just a simple dusting of powdered sugar to finish and your chocolate pound cake is ready to serve.

Serve this chocolate pound cake with a scoop of homemade ice cream and chocolate sauce or with a dollop of whipped cream and fresh berries to be fancy!

About This Recipe // Notes from Recipe Testing

A few weeks ago I shared my recipe for a classic old-fashioned vanilla pound cake. Then I shared my best strawberry pound cake recipe.

Of course the next logical step was to complete the trio of classic Neapolitan flavors and develop a chocolate pound cake too!

Besides, chocolate is my favorite dessert flavor, it was getting embarrassing being a baking blogger and not having a simple chocolate cake recipe to share! (If you're looking for a more complicated, show stopper chocolate cake, check out my mocha hazelnut naked layer cake.)

Personally, I find that the chocolate flavor in chocolate cakes often comes from a rich chocolate ganache or buttercream frosting, rather than from the chocolate flavor of the cake itself. Chocolate cake on its own without chocolate frosting, quite frankly, can be kind of boring!

So my top priority was to make a chocolate cake that could absolutely stand alone — no frosting needed. I did not want this to be a boring chocolate cake.

I dug into my pastry school notes and the science of chocolate and well, you'll find no boring chocolate cakes here.

We're using simple, easily accessible ingredients to make a loaf of chocolate pound cake is rich and moist with a dense, velvety, almost fudgy crumb and an intensely, unforgettably chocolate flavor.

While this chocolate pound cake uses my old fashioned vanilla pound cake as a base, changing a recipe from vanilla to chocolate is more complicated than you might think.

Cocoa powder is naturally very drying. Simply adding it or replacing some of the flour with it and making no another adjustments produces a cake that has an unpleasantly chalky texture. It needs more liquid to hydrate the cocoa powder.

So while I did replace some of the flour with cocoa powder, I added it with the wet ingredients — in this case, whole milk and full fat sour cream which add lots of moisture and tenderness to the cake crumb.

This process of "blooming" the cocoa powder in whole milk hydrates the cocoa powder and gives it a richer, more intense flavor. Mixing the bloomed cocoa powder with sour cream provides extra fat, which makes the chocolate cake moist, soft, and tender.

Finally, I replaced some of the white sugar with a dark brown sugar, which has molasses in it, adding even more moisture and flavor to the chocolate pound cake batter. It does mean you won't get quite as tall of a cake as if you used all white sugar, but the trade off is worth it for that soft, moist chocolate cake texture!

Ingredient Notes

Here are the ingredients that you'll need to make this chocolate pound 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.
• Sugar - Plain old regular granulated white sugar.
• 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.
• Whole Milk - For blooming the cocoa powder.
• Cocoa Powder - This recipe uses unsweetened natural cocoa powder like the classic box of Hershey's you can find in most grocery stores. Dark cocoa powder or Dutch process cocoa powders will also work here.
• Sour Cream - Full fat sour cream works best here — you really need the fat 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 topping the cake.

• Bring the butter to room temperature. Let the butter sit out at room temperature (70°F) for a couple hours. If you need to speed this process up, 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 — you're looking for a temperature of about 65°F.
• Bring the eggs to room temperature. Submerge the eggs in hot water for about 10-15 minutes prior to mixing. This helps them emulsify into the butter and sugar. If they're cold, they'll cool down the butter, and the batter will break and separate.
• Mix the dry ingredients together (NOT including cocoa powder). Whisk the flour, baking powder, and salt together in a bowl.
• Sift cocoa powder. 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.

Instructions - Blooming the Cocoa Powder

The first step is to bloom the cocoa powder. To do this, we're going to warm a pot of whole milk on the stove to "scald" it — which basically means bringing it to a temperature below boiling.

Milk boils at 212°F, scalded milk is somewhere around 170°-180°F.

To scald milk, whether you have a thermometer or not, 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.

It's important to do this step first so the chocolate mixture has time to cool slightly before you add it to the cake.

Instructions - Making the Cake Batter

To make this chocolate pound cake batter, we're using the creaming method of mixing, which I wrote about in my vanilla pound cake recipe. You can read more about it in detail in that post because it's basically the same process here up until we add the chocolate sour cream mixture.

When properly creamed together, the butter and sugar mixture will be light brown and look fluffy. If you rub it between your fingers the sugar granules should be almost entirely dissolved but still feel slightly gritty.

Scraping down the bowl and beater helps keep any sneaky bits of butter or sugar from getting trapped on the beater or in places the beater can't reach.

The next step is to add the eggs. And the goal is to add them in a way that won't break or collapse all the air we just worked into the butter.

So we're going to add them one at a time. This will give each egg plenty of time to emulsify into the butter and sugar before adding the next one.

Next, you're going to add approximately half of the bloomed cocoa and sour cream mixture.

Alternating adding the dry and wet ingredients on low speed and scraping down the bowl between additions helps prevent over mixing. An over mixed cake will be dense and tough, we don't want that!

Don't be overwhelmed by this alternating process. I know it sounds like a lot.

But it's very straightforward, and you can be approximate with what "one third" or "one half" is. It's more important that you're alternating the additions and mixing on slow speed, just until combined.

Mixing by hand to finish is is the best way to get any last bits of flour incorporated. Scrape to the very bottom of the bowl as you mix to make sure there's nothing hiding that still needs to be mixed in.

Again, this prevents over mixing and will help keep your chocolate pound cake soft and tender.

You'll end up with a luscious, thick, and fluffy chocolate cake batter that has a texture almost like a whipped chocolate frosting. Super dreamy and super smooth.

Spray an 8x4" loaf pan with non-stick spray, then line it with a parchment paper sling.

This line of butter step is technically optional but will help control how the top of your chocolate pound cake bakes. It will ensure the top of the cake cracks open in the middle.

Bake the 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.

It's hard to tell when a chocolate cake is done because you can't see any browning. So a few crumbs on the cake tester is the best way to know. You really don't want to over bake a pound cake or it will come out dry.

Some carryover cooking will happen in the pan, so err on the side of pulling it out a minute or two too soon rather than over baking it.

Let the chocolate pound cake cool in the loaf pan on a cooling rack for about 15-20 minutes.

Then use a knife to make sure the cake isn't stuck to the pan at the top or bottom (where there's no parchment paper) and use the parchment sling to lift it out and onto a cooling rack to finish cooling completely.

The chocolate pound cake will be very tall and domed when it first comes out of the oven, but will flatten out on top a bit as it cools.

NOTE: The cake must be completely cool before you add the powdered sugar topping or it will melt into the cake.

Dusting your chocolate pound cake with powdered sugar is optional, but I really like the way it looks. The sweetness is also really nice with the richness of the chocolate cake!

Suggested Equipment

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

• 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.
• 1 Pound Loaf Pan - A "1 pound" loaf pan is approximately 8 inches long, 4 inches wide, and 3 inches tall. A 1.25 pound loaf pan (9x5) will also work but your cake may not have the same height that mine does in these photos as there's more room for the batter to spread out. Metal pans work best for getting that golden brown crust. You may need to adjust baking time and temperature if using a glass pan (King Arthur Baking recommends lowering the temperature by 25°F and adding 10 minutes to the bake time).
• Quarter Pan Pre-Cut Parchment Sheets - I use these pre-cut parchment sheets to create a parchment sling that lines the pan to make the pound cake easier to remove. You'll have to trim about an inch off one of the long sides for it to fit, but they work very nicely!
• Metal Binder Clips - To secure the parchment paper in place so it doesn't fold in on top of the cake in the oven. Do not use plastic binder clips in the oven. I repeat, no plastic in the oven.
• 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.

Substitutions and Variations

Don't have the exact ingredients this recipe calls for? Here are some swaps and variations you can make. Avoid swapping any full fat ingredients for low fat alternatives — the fat is crucial for giving the cake a soft, tender texture.

• Natural Cocoa Powder - Dutch process cocoa powders will also work here.
• Sour Cream - Instead of sour cream, full fat plain Greek yogurt will work.
• Whole Milk - Instead of whole milk, you can use whole fat buttermilk.
• Dark Brown Sugar - Light brown sugar will also work.
• 8x4" (1 lb) Loaf Pan - A 9x5" loaf pan will also work, your cake will just be a bit shorter. A small 9x4" pullman pan will also work, giving your cake dramatic height and straight, vertical sides.
• Icing Glaze - Whisk together 60 grams of powdered sugar with 2 teaspoons milk to glaze the top of the cake.
• Powdered Sugar - Instead of a powdered sugar topping, dust the top of the cake with 1-2 tablespoons granulated sugar before baking. It will give you a crackly, flaky, crunchy top, but your cake may not rise as high. Skip the line of butter down the middle if you go this route.

Storage Notes & Freezing

This loaf of chocolate 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 a week.

The chocolate pound cake itself can be frozen for up to 3 months without powdered sugar on top. Defrost in the fridge, then dust with powdered sugar and let come to room temperature for serving.

Practical Tips and Recipe Notes

• If the 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.
• I use metal binder clips to help hold the parchment paper in place on the pan. The binder clips are optional, but keep the paper from folding in on top of the cake in the oven. Use metal binder clips only for this. Do not use plastic clips. I repeat, no plastic in the oven!!!
• 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."
• If you do the line of butter down the center of the cake, you may notice some white yellow coloring around the crack in the top of the cake — the powdered sugar dusting helps hide this!

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 texture, and the baking time. I recommend using an oven thermometer to make sure you're baking it at the right temperature!
