Ingredients 

For the brownie layer

  • 1 ⅓ cups all-purpose flour
  • 2 cups sugar
  • ¾ cup baking cocoa
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • ⅔ cup vegetable oil
  • 4 eggs, slightly beaten
  • 2 teaspoons vanilla

For the peanut butter fudge layer

  • 2 cups sugar
  • ½ cup milk
  • 1 ⅓ cups creamy peanut butter
  • 1 jar marshmallow creme, 7 oz.

For the chocolate ganache

  • ⅔ cup heavy whipping cream
  • 6 ounces semi-sweet baking chocolate, chopped

Instructions 

  • Preheat oven to 350°F. Lightly spray a 9×13-in. baking dish with cooking spray.

For the brownie layer:

  • In a mixing bowl, combine the flour, sugar, cocoa,baking powder and salt.
  • In another bowl, combine the oil, eggs and vanilla. Add the wet ingredients to the dry ingredients. Mix just until combined – Do NOT overmix. Spread into the prepared baking dish.
  • Bake for 20-25 minutes or until a toothpick inserted near the center tests clean. Cool on a wire rack.

For the peanut butter fudge layer:

  • In a medium saucepan, bring the milk and sugar to a boil. Boil for 4 minutes. Add the peanut butter and marshmallow creme and mix well. Quickly pour the mixture into the pan over the cooked brownie layer.
  • Refrigerate for one hour.

For the chocolate ganache layer:

  • Heat whipping cream in a small saucepan until hot but not boiling. Remove from the heat. Stir in chocolate until melted. Let stand for about 5 minutes. (The ganache is ready to use when the mixture mounds slightly when dropped from a spoon. It will become thicker as it cools.)
  • Pour the ganache over the fudge layer and tilt the pan so the ganache flows evenly over the top, covering it completely.
  • Allow to set completely before cutting into bars.

Notes

  • Due to the ganache, these store best in the fridge.

    So I am jealous and happy all at the same time. Jealous that I can't eat them and happy that I'm not eating them…those look extremely dangerous. Great job Jamie 🙂
