Recipe Tips

High Altitude: If you are making this Rich Chocolate Cake at a high altitude, please adjust the recipe according to your normal pattern. Because this recipe is fairly new to my repertoire and I live near sea level, I haven’t tested it for high altitude adjustments yet. I’d love to hear how it goes for you in the comment section. 

Buttermilk Substitute: If you don’t have buttermilk on hand, make your own. In a 1 cup measuring cup, add 1 tablespoon of lemon juice plus enough milk to fill to 1 cup (8 oz) of liquid. Let it sit for a few minutes, then add as you would normal buttermilk.

Dutch Process Cocoa: I add just a touch of Dutch process cocoa to this Rich Chocolate Cake to add a touch of dark chocolate color and flavor. Don’t substitute the natural cocoa powder out in this recipe. It needs the acidity of natural cocoa to rise properly. Dutch process cocoa has been processed with alkali so it will not react with the baking soda properly and your cakes will be flat and sad. 

This cake is as easy as it is delicious. I promise you will love every last bite. Let us know what special event in your life this cake is making into a dream come true in the comments below!

Instructions

Make the Rich Chocolate Cake.

  1. Preheat oven to 350*F (see note). 
  2. Prepare two 9-inch round cake pans. Spray bottom and sides of pans with non-stick cooking spray, line bottom with a circle of wax paper, then spray with non-stick cooking spray again. 
  3. In a large mixing bowl, sift together all-purpose flour, natural cocoa powder, sugar, salt, baking powder, baking soda, and Dutch process cocoa. Add buttermilk (see note), eggs, vegetable oil, and vanilla. Mix for one minute to combine. Batter will be thin. 
  4. Divide batter equally between two pans (about 25-26 ounces per pan) and bake for 25-30 minutes, until you can touch the center of the cake and it bounces back. Let cool in the pan for 5 minutes. Turn out onto wire cooling racks, peel the wax paper off the bottom and cool completely (2-3 hours) before decorating.
