Marshmallow Brownies

Recipe by
Great Lakes Energy Cooperative  
  • 1/2 cup butter, melted
  • 2 tablespoons cocoa powder
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 1 cup sugar
  • 3/4 cup flour
  • 1/4 teaspoon salt
  • 1 cup nuts, optional
  • 1/2 bag mini marshmallows (add more if you wish)


  • 1/4-1/3 cup condensed or evaporated milk (can also use whole milk)
  • 2 tablespoons butter
  • 2 cups powdered sugar
  • 1/4 cup cocoa powder
  • 1/8 teaspoon salt
  • 1 teaspoon vanilla or mint extract (mint is our fave)

Preheat oven to 350 F. In a medium bowl, add 1/2 cup melted butter and blend in 2 tablespoons cocoa powder. In a small bowl, beat the eggs, vanilla and sugar together. Add to the butter/cocoa mixture. Add the flour, salt and nuts and mix together (do not add marshmallows). Bake in greased (or lined with parchment paper) 8×8 pan for 30 minutes. Remove from oven and pour marshmallows on top and push down to melt them. To make the frosting, heat evaporated/condensed milk and butter until melted. Remove from heat and add the powdered sugar, cocoa powder, salt and vanilla/mint extract. Mix well. Pour over baked brownies and marshmallows. Allow to cool in the fridge for 30 minutes. Serve and watch ‘em disappear!

    Wondering if the frosting ingredient amounts are correct. I followed the recipe and the frosting turned out too thick to pour. Either need more milk or less powdered sugar.
