Step-by-Step Instructions

Chocolate Cake

  1. Preheat oven to 350°F (175°C). Grease two 8-inch round pans, dust with cocoa powder, and line bottoms with parchment.

  2. Add all dry ingredients to a stand mixer bowl and stir to combine.

  3. In a separate bowl, whisk wet ingredients, slowly adding hot water to avoid cooking the eggs.

  4. Add wet ingredients to dry and mix on medium for 2–3 minutes. Batter will be thin.

  5. Divide batter evenly between pans.

  6. Bake for 45 minutes, or until a tester comes out mostly clean.

  7. Cool 10 minutes in pans, then turn out onto a rack to cool completely.
