Ingredients

  • 1 Box peanut butter brownie mix any brand
  • 2-4 tbsp peanut butter pouch was included with my cake box
  • 1 egg
  • 2 tbsp water

  • Mix cake with water, egg and oil. Use an electric mixer or whisk and blend until smooth.
  • Place a parchment paper in your square tin and pour the mixture evenly.
  • Drizzle peanut butter over the mixture, you can add as little or as much you like. I sometimes prefer to add 2 spoons extra to make brownies creamier.

  • Leave it to cool it down on a cooling rack then cut into little squares. Enjoy!
