This decadent chocolate cake is full of chocolatey, moist perfection with a soft, tender crumb. This cake gets its rich, dark flavor and appearance by using a combination of black cocoa and regular cocoa.
Prepare two 8" cake pans by lining the bottom with parchment paper or greasing the pans. Alternatively, this recipe will make 18 cupcakes or one 10" round cake pan.
Combine flour, cocoa powder, sugar, cornstarch, baking powder and baking soda in the bowl of a stand mixer. If mixing by hand or with a hand mixer, combine ingredients in a large mixing bowl.
Add oil and eggs. Mix until combined.
Slowly pour brewed coffee into bowl while continuing to mix, scraping the bowl occasionally. The batter should be smooth.
Divide batter between the two prepared cake pans.
Bake for 10 minutes at 275℉
Increase oven temperature to 350℉ and bake an additional 25 minutes, or until cake is fully risen and a toothpick inserted in the center of the cake comes out clean.
Place cakes on a rack and allow to cool completely before unmolding. Unmold by running an offset spatula or knife around the inside of the cake pan and flip the pan over onto a platter.
