Here you have it, my new favorite chocolate cake! I’ve made three chocolate cakes this week (and believe it or not I’m still not sick of chocolate cake) but I’ve been on a mission to create my idea of the best chocolate cake.
I already have my favorite chocolate frosting that will likely never be replaced so that part was easy, but my old favorite chocolate cake is now just that, an old favorite. I wanted a cake with a little more chocolate (or cocoa anyway), so I decided it was time to create my own chocolate cake recipe.
Here’s the rundown in what I’m looking for in a chocolate cake:
- Chocolate flavor. This cake, loaded with it. The boiling water intensifies the chocolate flavor of the cocoa. I’m starting to think it’s a must for all chocolate cakes.
- Moisture. We all hate dry cakes. I like mine really moist. This one, check.
- Crumb texture. Is it soft? Is it fluffy or dense? Does it have stability? Soft is definitely a must and I like my chocolate cake somewhere between fluffy and dense. I’m not a big fan of the chocolate cakes that are so fluffy they just crumble apart and don’t have much structure but I also don’t want it so dense that it’s like eating a cheesecake.
- Perfect frosting. An incredible frosting is just as important as a good cake. It is going to crown the cake after all. This frosting is likely the best chocolate frosting you’ll ever make. Just sayin :).
I really hope you love this chocolate cake as much as I do. Find a reason to celebrate and enjoy!

- 1/2 cup (110g) packed light-brown sugar
- 3/4 cup (70g) unsweetened cocoa powder (scoop and level to measure)
- 1 tsp baking soda
- 3/4 tsp salt
- 1 cup (235ml) boiling water*
- 3/4 cup (175ml) vegetable oil or canola oil
- 1/4 cup (56g) unsalted butter**, melted
- 2 large eggs
- 3 large egg yolks
- 1 Tbsp vanilla extract
- 2 cups (256g) all-purpose flour (spoon and level to measure)
- 1/2 cup (116g) sour cream
- 1/3 cup (80ml) milk
Chocolate Buttercream Frosting
- 1 1/2 cups butter, at room temperature (I like to use 1 cup unsalted and 1/2 cup salted)
- 4 cups (480g) powdered sugar
- 3/4 cup (70g) unsweetened cocoa powder
- 3 - 4 Tbsp heavy cream
- 1 tsp vanilla extract
- For the cake:
Preheat oven to 350 degrees. Butter two 9-inch round cake pans then line bottom of each with a round of parchment paper. Butter parchment paper. Wrap cake pans with baking strips for the most level cakes***.
In a large, heat proof mixing bowl, whisk together granulated sugar brown sugar, cocoa powder, baking soda and salt. Carefully pour boiling water in to cocoa mixture and immediately whisk to blend well. Allow to cool 5 minutes.
Using an electric hand mixer set on low speed blend in vegetable oil and melted butter until combined. Add eggs, egg yolks and vanilla extract and blend just to combined. Then add flour and blend until combined, and finish by blending in milk and sour cream just until combined.
Divide mixture evenly among 2 prepared pans. Bake in preheated oven until toothpick inserted into center of cake comes out clean or with a few moist crumbs, about 29 - 34 minutes. Allow to cool in pan 5 minutes, run butter knife around edge of cake and invert onto a wire rack and allow to cool completely.
Trim tops from cake to form an even layer. Add frosting to top of one round then top with second cake and frost top and sides of cake. Store in an airtight container.
- For the chocolate buttercream frosting:
In a the bowl of an electric stand mixer, fitted with a paddle attachment, whip butter on moderately high speed until very pale and fluffy (nearly white in color), about 6 - 8 minutes, occasionally scraping down sides of the bowl.
Add in cocoa powder, powdered sugar, 3 Tbsp heavy cream and vanilla and mix on low speed until combine. Scrape down the sides of the bowl as needed and add up to 1 tbsp additional cream to thin if needed.
Increase mixer to medium-high speed and whip mixture until pale and very fluffy about 4 - 5 minutes, occasionally scraping down sides of the bowl. Keep frosting cool or it will start to melt if it rises above about 70 degrees.
- *Water should be carefully measured after boiling. If measured before you won't have the same amount as some water would evaporate.
- **Cake portion originally did not include any butter, I've updated it to include this for an even moister more fudgy cake. Also updated sour cream originally listed as 1/3 cup, increased to 1/2 cup.
- ***Another update to this recipe is to use cake strips. You can buy them online (I have these) or you can make your own. I recommend using them or cake does dome a bit on top so if you use them you'll have taller more even cake layers that don't need to be trimmed to level.
