Sturdy Yet Moist and Fluffy Chocolate Cake

This is the chocolate cake I reach for when it has to work.

It’s soft, deeply chocolatey, and incredibly moist—but strong enough to stack, carve, and hold its shape without collapsing. No guesswork. No fragile layers. Just a reliable, bakery-style chocolate cake that delivers every time.

Why You’ll Love This Recipe

This chocolate cake is based on my Fluffy and Buttery Vanilla Cake, which has been one of the most popular recipes on my site. After getting tons of requests for a chocolate version—this is it.

It’s the kind of recipe every baker needs in their back pocket. It works for birthdays, celebrations, or even wedding cakes—and pairs well with almost any frosting.

Taste and Texture

The cake has a soft crumb but it is sturdy enough for stacking and carving. It is not fudgy but it is definitely moist and has a concentrated chocolate flavor without being too sweet.

Thanks to the cocoa dissolved in boiling water; it gives the cake an extraordinarily full and intense chocolate flavor. I used the same method in making my favorite basic chocolate cupcake.

Overall, I thought this chocolate cake is great to be in a baker’s back pocket. It is great for any special occasion and any frosting will work with it!

Baking in Different Cake Pan Sizes

Here is a chart of the amount of ingredients you’ll need depending on pan size:

Follow the same procedure as written in the recipe but you may need to adjust the baking time. Remember that the time indicated below is only a guide as not all ovens are the same.

⭐️PRO TIP: Use a thermometer. ⭐️
Cakes are done at 200–205°F (93–96°C)—this is the most accurate way to avoid dry, overbaked layers.

---

For the purpose of testing, I baked each size in two different cake pan heights:

1. For the 6-inch cake recipe, I used a cake pan that is 3 inches in height (6×3).
2. For the 8-inch cake recipe, I used a cake pan that is 2 inches in height (8×2).

6-inch Chocolate Cake for Stacking

For the 6-inch cake recipe, I divided the batter into two 6×3 pans.

This is the exact baking pan I use and I really do recommend this brand (not sponsored – I just really love their baking pans!) .

This yields tall layers (about 3 inches each before leveling). After torting each cake into two layers, you’ll have four layers total—perfect for a tall, bakery-style cake.

After filling and frosting, the final cake can reach over 5 inches tall.

TIP: If you only have a cake pan that is less than 3 inches in height, an alternative is to line parchment around the cake pan for added height, just like what I did in my Vanilla Cake.

8-inch Chocolate Cake

For the 8-inch cake recipe, I divided the batter into three 8×2 pans.

Each layer bakes up close to 2 inches tall. The cakes rise right to the top, and using cake strips helps minimize doming for more even layers.

You can also use two 8×3 pans—just increase the baking time.

This time, I used cake strips, and you can really see the difference in terms of doming!

Ingredients & Substitutions

Shop efficiently (treat this as your grocery list) and gather your ingredients at home without running circles in your kitchen. (i.e. One trip to the fridge to get all your dairy needs.) You can still find the full printable recipe at the end of this post.

***The ingredient quantities listed below are for the 8-inch recipe. ***

REFRIGERATED:

• butter. 340g of unsalted butter, at room temperature. What is Room Temperature Butter?

• eggs. You need 300 grams of eggs (weight is without shell). That is about 6 large eggs, at room temperature.

PANTRY:

• Dutch processed cocoa. Sometimes called alkalized cocoa; it is unsweetened cocoa that has been treated with an alkali to make it pH neutral. You need 180grams.

• water. 710g or about 3 US cups of boiling water.

• flour. 500g of all-purpose flour – measured by weight and not by cups. This recipe uses a lot of flour and any excess amounts will make your cake dry and too dense. I don’t recommend using cake/pastry flour as we need a higher protein content to make this cake sturdy.

• baking soda. 14 grams or 1 tablespoon. Baking Soda loses its leavening power over time so always check yours is still good.

• baking powder. 3 grams or 3/4 teaspoon. Baking powder do expire so always ensure your batch is still good.

• Salt. 9 grams or 1.5 teaspoon of fine sea salt/ table salt.

• sugar. 600 grams or 3 cups of granulated white sugar. You can use caster sugar in place of white granulated sugar, but be sure to measure by weight, not volume, as the finer grain size means it packs differently in a measuring cup.

How To Make The Best Chocolate Cake for Stacking & Carving

The steps to make this chocolate cake are actually simple.

STEP 1. MISE EN PLACE. Prepare your oven by preheating it to 350 F (175 C). Note that I am using a conventional oven (no fan).

Grease and line the bottom of each cake pan with parchment paper. Instead of dusting the pan with flour, use cocoa powder.

In a separate bowl, prepare the flour mixture by sifting together your dry ingredients: flour, baking powder, baking soda, and salt.

STEP 2. Preferably in a bowl with a spout, whisk the cocoa and boiling water until smooth. Set aside to cool while you make the batter.

STEP 3. In the bowl of a stand mixer fitted with a paddle attachment, beat the butter and sugar on medium speed until light and fluffy. This process takes about 8 minutes – the butter should turn very pale yellow, almost white in color.

STEP 4. Add eggs, one at a time, beating until each addition is incorporated. Scrape the bottom and sides of the bowl.

STEP 5. Add the flour mixture four times, alternating with the cocoa mixture in three parts, beating until each addition is incorporated.

STEP 6. Divide the batter in your pans and bake until a cake tester inserted into the centers come out clean. Cool the cakes in the pans on wire racks before using them.

NOTE: Not sure what’s medium, medium-low, or low speed in your mixer? Read this Stand Mixer Speed Control Guide.

Freezing and Make Ahead

After the cakes have been removed from the pan and have completely cooled down. Double wrap each layer with plastic/saran wrap and keep in the fridge for up to 2 days. I did this when I used the vanilla version of this recipe for a wedding cake.

If longer than 2 days, I suggest keeping them in the freezer instead. If freezing, double wrap it with plastic/saran wrap then wrap again in foil. The first layer keeps the cake tight and fresh and the aluminum foil ensures no condensation will seep in.

When you are ready to use the cake, transfer the wrapped cakes from the freezer to the refrigerator one day before assembling. Take them out of the freezer container to thaw, but leave them wrapped in plastic wrap/aluminum foil.

The cakes take at least 8 hours to thaw completely in the refrigerator. Make sure you’re thawing the cakes while they’re still in the wrapping. Condensation forms as foods thaw. This way the condensation will form on the wrapping, not the cake.

If you need to make a cake like this in Vanilla, head on to Fluffy and Buttery Vanilla Cake recipe.

I’ve used this recipe to make a 3-tiered wedding cake so I can say that while it is soft and fluffy, it is firm enough to use in multi-tiered cakes.
