  • 0.5 Teaspoon Sea Salt
  • 125g Creamy Peanut Butter
  • 2 Tablespoons Powdered Sugar
  • 150g Reese’s Peanut Butter Cups

Instructions:

  1. Preheat your oven to 180°C and line your baking pan with parchment paper.
  2. Whisk the 170g hot melted butter with 200g granulated sugar and 100g brown sugar vigorously for 2 minutes until the mixture looks pale and slightly gritty.
  3. Add the 2 eggs and vanilla, whisking for another minute until the batter is glossy and smooth.
  4. Sift in 75g cocoa powder, 95g flour, and 0.5 teaspoon salt.
  5. Gently fold the dry ingredients in with a spatula until no white streaks of flour remain.
  6. In a separate small bowl, stir the 125g peanut butter and 2 tablespoons powdered sugar until combined and slightly stiff.
  7. Pour the chocolate batter into the pan, then drop spoonfuls of the peanut butter mixture on top.
  8. Use a butter knife to swirl the two together until you see a beautiful marbled pattern.
  9. Press the 150g chopped Reese’s cups and Reese's pieces into the top.
  10. Bake for 30 minutes until the edges are set but the center still jiggles slightly.
