  • 2 cups all-purpose flour.
  • ¾ cup cocoa powder.
  • 2 cups sugar.
  • ½ cup butter.

Instructions
 

Preparing the Night Before

  • Feed your sourdough starter: Ensure your sourdough starter is active and bubbly by feeding it with flour and water.
  • Mix the batter: Combine the sourdough starter, flour, cocoa powder, sugar, eggs, and other ingredients in a bowl. Let it sit at room temperature overnight.
  • Fermentation: This 12-hour resting period allows the sourdough culture to interact with the other ingredients, enhancing the flavor and texture of the cake.
  • Cover and store: Cover the bowl with plastic wrap or a towel to prevent drying out and store it in a warm place overnight for up to 12 hours.

Baking Process

  • Preheat the oven: Start by preheating your oven to 350 degrees.
  • Grease and flour the pan: Prepare your cake pan by greasing it with butter or oil and dusting it with flour to prevent sticking. I used my cast iron skillet.
  • Pour the batter: Transfer the fermented batter into the prepared cake pan, spreading it evenly.
  • Bake the cake: Place the cake pan in the oven and bake for 35 minutes, until a toothpick inserted in the center comes out clean.
  • Cooling the cake: Once baked, let the cake cool in the pan for a few minutes before transferring it to a wire rack to cool completely.
  • Slicing and serving: Slice the cake once it's cooled and serve it with your favorite toppings or frostings.

Making the Chocolate Frosting

  • Whip the butter and cocoa powder together until smooth.
  • Add in vanilla extract and powdered sugar.
  • Add in milk slowly while whipping until light and fluffy.
  • Spread evenly on the cake after the cake has cooled.
