Chocolate Cake & Cupcakes

Chocolate Cake and Cupcakes

This very decadent chocolate cake and cupcake recipe uses two different cocoa powders for extra chocolate flavor. Pair it with lots of different buttercream, filling, and drip flavors. It is one of my favorites to eat!
Make sure to read all important notes below.

Ingredients

½ cup unsalted butter (1 stick)
1¾ cup + 1 Tbsp granulated sugar
2 eggs
1 Tbsp + ½ tsp vanilla extract
3 Tbsp vanilla Greek yogurt

1¾ cups all-purpose flour
¾ cup unsweetened cocoa powder, sifted
⅜ cup black cocoa powder, sifted
2 tsp baking powder, sifted
¼ tsp baking soda, sifted
¼ tsp salt

¾ cup strong hot coffee
¼ cup buttermilk

½ cup canola oil

Optional: ½ to 1 cup chocolate chips

Directions

Preheat oven to 350°.

In a stand mixer with the whisk attachment or using a hand mixer with the whisk attachment and a large bowl, cream the butter and sugar together. Add the egg. In a separate bowl, beat the two egg whites with a hand mixer or by hand until white and frothy. Add egg whites to mixture. Add the vanilla extract and Greek yogurt and mix this all together.

In a separate bowl, whisk together the all-purpose flour, cake flour, salt, sifted baking powder, and sifted baking soda.

Add dry ingredients and buttermilk into the butter/sugar/egg mixture, alternating adding the dry ingredients with the buttermilk.

Add the canola oil and continue to mix only until well combined. Do not overmix beyond this. Hand stir in chocolate chips, if desired.

If you are making cake layers, spray your cake pans with canola spray and/or add a parchment circle to prevent sticking. Fill each cake pan approximately ½ to ⅔ full of batter.

If you are making cupcakes, add baking liners to cupcake pans and fill each approximately ½ to ⅔ full of batter. A cookie dough scoop or ice cream scoop is very helpful for filling cupcake pans.

Bake at 350° until a toothpick comes out cleanly from the center of the cake layers or cupcakes. Baking times will vary based on oven strength, altitude, cake layer size, and many other factors, so I do not give a specific baking time. I recommend just checking with a toothpick periodically.

Roughly, cupcakes bake in 12 to 18 minutes, and cake layers can take anywhere from 20 minutes to 45 minutes.

Allow cake layers to cool sitting in their pans on a wire rack for 10-15 minutes, then run a knife around the edge of the pan to help release the layer. If planning to decorate on another day, while still warm, wrap the layer tightly in plastic wrap and place into airtight bag or container, then store in the freezer. If planning on decorating same day, allow to cool completely before decorating. My preference is to stack/assemble and frost frozen cake layers, as they are more solid to work with, and this preserves moisture.

Allow cupcakes to cool in their pans for 5 minutes, then transfer to wire racks just until warm (keep liners on). If planning to decorate on another day, place cupcakes into an airtight bag and then place into another airtight container or bag, then store in the freezer. If planning on decorating same day, allow to cool completely before decorating.

Important Notes

Once covered and decorated in buttercream frosting, cakes and cupcakes may be out on the counter at room temperature for a few hours, or stored in the refrigerator for up to 4 days. Keep cupcakes and cut cake (with layers exposed) in an airtight container. Uncut cakes with buttercream intact does not need to be in an airtight container.

This recipe (and any of my others) can be marbled together with vanilla cake or another flavor or color to create marble cake. Alternate adding scoops of this batter and vanilla/other batter into the same cake pan or cupcake liner and gently swirl together with a butter knife just until swirled, not mixed. Bake as directed above, until a toothpick comes out cleanly in the center.

Recipe outcomes are affected by oven performance, altitude, climate, brands/types of ingredients, and many other factors, so some variation in results may occur.

If intending to sell baked goods, be sure to verify approved recipes and ingredients with your state’s cottage foods governing entity.
