  • 3/4 cup flour
  • 1/4 cup unsweetened cocoa powder sifted
  • 1 tsp baking powder
  • 1/4 tsp salt
  • 1/2 cup butter melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 2 tsp vanilla
  • 2 cups mini marshmallows

For the frosting:

  • 1/4 cup butter melted
  • 1/4 cup cocoa powder sifted
  • 1/4 cup evaporated milk
  • 2 cups powdered sugar sifted
  • 1 tsp vanilla


  • Preheat the oven to 350 degrees. Butter or spray a 9-inch pie plate or spring form pan. Set aside. Whisk together the flour, cocoa powder, baking powder and salt in a bowl.
  • In a medium bowl, mix the butter and sugar with an electric hand mixer, beat in the eggs and vanilla for 1-2 minutes, until the mixture becomes fluffy and light in color.
  • Add to the dry ingredients and mix until smooth, being careful not to over-mix as this will cause the brownie to be more cake-like in texture. Pour into the prepared pan.
  • Bake on a middle shelf of the oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean.  
  • While the brownie is baking make the chocolate frosting. Combine all ingredients together in a medium bowl and mix on medium low speed with a hand mixer, until smooth.
  • Remove from the oven and immediately sprinkle the marshmallows on top and return to the oven for a few minutes to melt the marshmallows. 
  • Remove from the oven and carefully spread the chocolate frosting over top. Let cool completely. Cut into wedges to serve.
