Why You'll Love This Recipe

  • A great recipe for those peanut butter lovers that a little chocolate craving too!
  • One of my favorite desserts to go with a tall glass of cold milk!
  • Fudgy chocolate brownies with a smooth peanut butter layer and chocolate ganache is better than peanut butter cups any day!

Ingredient Notes and Substitutions

  • Peanut Butter - You'll want to use creamy peanut butter for this recipe. Crunchy peanut better doesn't work well. Natural peanut butter is fine.
  • Brownie Mix - Use your favorite mix that makes a 9x13 pan of chewy brownies. You'll be following the instructions and ingredients required on the box to prepare them. Trust me, no one will know that these aren't really "homemade" fudgy brownies.
  • Olive Oil, Water & Eggs - These are the ingredients required for the Betty Crocker box mix I chose to use.
  • Chocolate Chips - Whether you use milk chocolate chips or semi-sweet chocolate chips is up to you. Semisweet chips do cause the chocolate ganache to set up firmer which I think is a plus.

  • Put the dessert back in the fridge and chill for at least 4 hours.
