  • Brownie
  • 1/2 cup vegetable oil (120g)
  • 1 cup sugar (200g)
  • 1 teaspoon vanilla
  • 2 eggs
  • 1/2 cup unsifted all-purpose flour (64g)
  • 1/3 cup cocoa powder 35g
  • 1/4 teaspoon baking powder
  • 1/4 teaspoon salt
  • Filling:
  • 1/2 cup chopped milk chocolate (114g)
  • 1 tablespoon peanut butter (15g)
  • 1/2 cup chopped white chocolate (114g)
  • 1 tablespoon peanut butter (15g)


  • Preheat the oven to 350F / 175C. Grease a muffin tin.
  • In a bowl mix together sugar, vanilla, oil, and eggs. Add the cocoa, flour, baking powder, and salt. Stir well.
  • Fill each greased muffin tin 3/4 full (I got 8). Bake for 25 minutes, or until the center is firm to the touch.
  • Cool in pan for 5 minutes and then make a dent in the middle of each brownie with the back of a spoon or the tip of a wooden spoon. Let it cool completely in the pan before removing it.
  • While the brownie cups are cooling, cut the chocolate into small chunks (or use chocolate chips).
  • Add milk chocolate and peanut butter to a small bowl and white chocolate and peanut butter into another small bowl. Melt each bowl of chocolate in the microwave for 1 and a half minutes, stopping every 30 seconds to stir. Mix well.
  • Divide the chocolate milk into the brownie cups (I left a teaspoon of this chocolate to decorate the cups at the end).
  • Let it stand for 5 minutes. Add the white chocolate over the milk chocolate. If desired, put the rest of the milk chocolate in a bag, cut the tip, and decorate the brownies.
  • Store in an airtight container for up to 3 days at room temperature. Enjoy with a glass of cold milk!


Keep in an airtight container, at room temperature for up to 5 days.
