Ingredients

CAKE

  • 320 g Flour
  • 120 g Olive Oil
  • 120 g Active Starter
  • 25 g + 50g Cocoa Powder
  • 240 g Hot Coffee
  • 3 Eggs
  • 300 g Sugar
  • 250 g Buttermilk or milk
  • 80 g Greek Yogurt
  • 2 tsp Baking Soda
  • 10 g Vanilla

WHIPPED MASCARPONE

  • 8 oz. Mascarpone Cream
  • 454 g Heavy Cream
  • 120 g Powdered Sugar
  • 50 g Cocoa Powder

Instructions

DAY ONE

  1. Mix your flour, olive oil, active starter, 25g of cocoa powder, and warm coffee thoroughly. Leave at room temperature for 12-24 hours to fully ferment.

DAY TWO

  1. Preheat the oven to 350°F. Then, add the eggs and sugar to the bowl of a stand mixer. Using the whisk attachment, beat the mixture until light and fluffy.
  2. Add the buttermilk, Greek yogurt, remaining cocoa powder (50g), vanilla, and baking soda. Whisk until combined.
  3. Lastly, add your fermented flour mixture. Whisk until combined, starting at a low speed to avoid splashing. The batter should become smooth.
  4. Divide the batter into your greased cake pans (Recommended: (2) 9” round cake pans). Bake for 25-30 minutes, until the centers are fully set.
  5. While your cakes cool, prepare the whipped mascarpone. Add your mascarpone and heavy cream to a stand mixer with the whisk attachment. While whisking, slowly add the powdered sugar and cocoa powder, whisking until stiff peaks form.
  6. Assemble your cake once it is fully cooled, and ENJOY!
