  • Author: Cullys Kitchen


  • ½ cup plus 2 tablespoons boiling water
  • 2 ounces unsweetened chocolate (chopped or shaved fine)
  • 1/3 cup Dutch cocoa powder
  • 2 ½ cups sugar
  • ½ cup plus 2 tablespoons vegetable oil
  • 2 large eggs plus 2 large egg yolks
  • 4 tablespoons butter (melted – I used unsalted)
  • 2 teaspoons vanilla extract
  • 1¾ cups all-purpose flour
  • ¾ teaspoon salt
  • 1 cup peanut butter chocolate chips (or ½ cup peanut butter chips and ½ cup milk chocolate chips)
  • ½ cup marshmallow cream


  1. Preheat oven to 350F.
  2. Line a 13 x 9 baking pan with aluminum foil and lightly spray with cooking spray.
  3. In a large bowl mix together the boiling water, unsweetened chocolate, and cocoa until chocolate is melted. Mix in the sugar, oil, eggs, egg yolks, butter, and vanilla until well combined.
  4. Gently mix in the flour and salt until just moist and then fold in the chocolate and peanut butter chips; pour the mixture into baking pan.
  5. Dollop spoonful’s of marshmallow crème over the top and using the tip paring knife swirl it into the batter.
  6. Bake for 30 – to 35 minutes or until a toothpick inserted comes out with just a few crumbs left on it.
  7. Note: if you don’t care for marshmallow crème just leave it out.
