For the Brownies:

  • 1 cup melted butter (or 1 stick of butter and 1 stick of margarine)
  • 2 cups sugar
  • 1/2 cup unsweetened cocoa
  • 4 large eggs, lightly beaten
  • 1 teaspoon vanilla extract
  • 1/8 teaspoon salt
  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups coarsely chopped pecans, toasted
  • 1 (10.5-ounce) bag miniature marshmallows

For the Chocolate Frosting:

  • 1 (16 oz) package powdered sugar, sifted
  • 1/2 cup milk
  • 1/4 cup butter, softened
  • 1/3 cup unsweetened cocoa


1. Brownie Preparation:

  1. Whisk and Combine: In a large bowl, whisk together the melted butter and the next 5 ingredients until well combined.
  2. Stir in Flour and Pecans: Add the flour and chopped pecans to the mixture, stirring until a smooth batter forms.
  3. Bake: Pour the batter into a greased and floured 15- x 10-inch jellyroll pan. Bake at 350°F for 20 to 25 minutes or until a wooden pick inserted in the center comes out clean.
  4. Marshmallow Topping: Remove the pan from the oven and evenly top the warm cake with miniature marshmallows. Return to the oven and bake for an additional 5 minutes until the marshmallows are gooey and lightly browned.

2. Chocolate Frosting:

  1. Mix Ingredients: While the cake is baking, prepare the chocolate frosting by beating together the powdered sugar, milk, softened butter, and unsweetened cocoa until smooth.

3. Assembling and Serving:

  1. Drizzle Frosting: Once the cake is out of the oven, drizzle the chocolate frosting evenly over the warm cake and marshmallows.
  2. Cool Before Cutting: Allow the Mississippi Mud Cake Brownies to cool completely before cutting into squares. This step ensures neat and clean servings.
