  • 1/3 cup brown sugar
  • 1/3 cup strong coffee
  • 1/2 cup dutch process cocoa
  • 1 tablespoon butter
  • 1 teaspoon vanilla


  • 1 1/2 cups (192g) all-purpose flour
  • 1/2 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/2 cup (1 stick or 113g) salted butter, warm but not melted
  • 1/2 cup 100g granulated sugar
  • 1/2 cup 100g packed brown sugar
  • 2 large eggs, room temperature
  • 1/2 cup cold coffee
  • 1 teaspoon vanilla



  1. Place all ingredients in the first part into a saucepan over low heat. Stir until they are fully incorporated, 5-7 minutes. Remove from heat and allow to cool a bit. It should be a little thick and similar to custard.


  1. In a medium bowl, sift flour, baking soda, and baking powder together.
  2. Add 1/2 cup warm butter, sugars, eggs, cooled coffee, and vanilla to the flour mixture and mix with a hand-held mixer until fully combined. (or stir by hand)
  3. Add the chocolate mixture from the FIRST PART to the ingredients from the SECOND PART. Stir by hand until all ingredients are well combined.
  4. Pour onto a prepared (sprayed or lined with parchment) baking sheet (I used a 10x15in baking sheet). Smooth out the batter and gently tap on the counter.
  5. Bake in a 350°F oven for 16-22 minutes, or until the center no longer appears wet and an inserted toothpick is removed with a few crumbs.
  6. Allow to cool before frosting.
