Here’s to a classic chocolate layer cake — rich, fudgy, and decadently chocolatey. This cake delivers a deep Devil’s food-like chocolate flavor, layered and finished with a smooth chocolate buttercream frosting. Topped with generous swirls of buttercream, it’s ideal for birthdays, weekend treats, or any celebration that calls for an unforgettable dessert.
This recipe is a variation of a simple one-bowl chocolate cupcake batter, so the cake comes together quickly and with minimal fuss. Whisk the ingredients in a single large bowl — no stand mixer required — then finish with a luscious chocolate buttercream for classic layered cake perfection.
Easy Chocolate Layer Cake
One-bowl convenience: The batter comes together in minutes in a single bowl. This makes the recipe fast, tidy, and accessible for bakers of all levels.
Room-temperature ingredients: Use eggs, milk, and Greek yogurt at room temperature to help the batter mix evenly and produce an extra-moist crumb.
Boiling water and espresso: Adding boiling water blooms the cocoa and helps melt the chopped chocolate into the batter for intense chocolate flavor. A small amount of instant espresso enhances the chocolate without adding a coffee taste; omit it if you prefer.
Baking Pans
This recipe is designed for two 8-inch round cake pans for nicely sized layers and an ideal cake-to-frosting ratio.
For a three-layer cake, divide the batter evenly between three 8-inch round pans and shorten the bake time slightly.
You can also use 9-inch pans: expect slightly shorter bake times — watch the cake closely and test for doneness with a toothpick.
Pro tip: For consistent layers, weigh each pan as you divide the batter to ensure even layers and uniform baking.
Chocolate Sheet Cake
If you prefer a sheet cake, pour the batter into a 13 x 9-inch pan for an easy dark chocolate sheet cake. Bake briefly and finish with the same chocolate buttercream for a quick, crowd-pleasing dessert.

Ingredients
Cake
- 1 1/2 cups all-purpose flour
- 3/4 cup unsweetened cocoa
- 1 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 cup granulated sugar
- 1/2 cup light brown sugar
- 2 large eggs plus 1 egg yolk, at room temperature
- 1/2 cup milk, at room temperature
- 1/2 cup plain fat-free Greek yogurt, at room temperature
- 1/2 cup vegetable or canola oil
- 2 tsp vanilla extract
- 2 tsp instant espresso (optional)
- 1/2 cup boiling water
- 4 oz semisweet chocolate, finely chopped
Chocolate Buttercream Frosting
- 1 cup unsalted butter, softened
- 1/2 tsp salt
- 3/4 cup unsweetened cocoa, sifted
- 2 tsp vanilla extract
- 2 1/2 cups powdered sugar
- 5 Tbsp heavy cream (adjust for desired consistency)
Instructions
- Preheat the oven to 350°F. Prepare two 8-inch round cake pans by spraying or greasing and lining if desired.
- In a large bowl, whisk together the flour, cocoa, baking powder, baking soda, and salt. Make a well in the center.
- Add the granulated and brown sugars, eggs and yolk, milk, yogurt, oil, and vanilla to the dry ingredients. Whisk just until combined.
- Dissolve the instant espresso in the boiling water, then whisk the mixture into the batter until smooth. Fold in the chopped semisweet chocolate.
- Divide the batter evenly between the prepared pans and smooth the tops. Tap the pans on the counter to release air bubbles.
- Bake about 28–30 minutes for 8-inch pans, or until the cakes spring back to the touch and a toothpick inserted near the center comes out with a few moist crumbs. Cool the cakes completely in the pans on a wire rack.
- For the frosting, beat the softened butter and salt until combined. Gradually add the sifted cocoa with the mixer on low, then mix in the vanilla. Add the powdered sugar one cup at a time, alternating with 1 tablespoon portions of heavy cream. Scrape the bowl as needed. Add the remaining cream and beat on medium for about 1 minute until light and fluffy.
- To assemble, place one cake layer on a stand or serving plate. Spread about 1 cup of frosting over the layer. Top with the second layer and spread another cup of frosting, allowing the frosting to swirl over the edges if you like. Apply frosting to the sides and smooth gently with a bench scraper or spatula. Decorate with swirls or piping as desired.
- Store leftover cake covered in the refrigerator. Bring to room temperature before serving for the best texture and flavor.
Equipment
- 8-inch round cake pans (or 9-inch pans for a wider, shorter cake)
- Mixing bowls and whisk
- Offset spatula and bench scraper for frosting
- Wire rack for cooling
Notes
Cake layers: This batter works for two or three layers. If making three layers, divide the batter evenly between three pans and reduce the bake time slightly. Always test for doneness.
9-inch pans: Use slightly shorter bake times for 9-inch pans — check at the earlier end of the time range to avoid overbaking.
Sheet cake option: For a sheet cake, bake in a 13 x 9-inch pan until a toothpick comes out with a few crumbs, then frost as directed.
Instant espresso: A small amount enhances chocolate flavor; omit if you prefer no espresso.
