Frosted Chocolate Marshmallow Cake

Total Time

Prep: 25 min. Bake: 30 min.


12-16 servings

My sister-in-law gave me this recipe many years ago—one of us will often make it for family gatherings. The cake is moist and rich.


  • 1/2 cup shortening
  • 3 ounces unsweetened chocolate
  • 1 cup water
  • 2 cups sugar
  • 2 large eggs
  • 1/2 cup whole milk
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1-1/4 teaspoons baking soda
  • 1/4 teaspoon salt
  • 20 large marshmallows
  • 4 ounces unsweetened chocolate, chopped
  • 1/4 cup butter, cubed
  • 1/3 cup whole milk
  • 1 teaspoon vanilla extract
  • 3-3/4 cups confectioners' sugar


  1. In a small microwave-safe bowl, melt shortening and chocolate at 50% power; stir until smooth. Add water; cool slightly. Transfer to a large bowl. Add the sugar, eggs, milk and vanilla; beat well. Combine the flour, baking soda and salt; add to batter and mix until smooth.
  2. Pour into a greased 13-in. x 9-in. baking pan. Bake at 350° for 28-32 minutes or until a toothpick inserted in the center comes out clean.
  3. Arrange marshmallows over the top; bake 5 minutes longer or until marshmallows are softened. Spread marshmallows evenly over top of cake. Cool on a wire rack.
  4. For icing, in a large microwave-safe bowl, melt chocolate and butter; stir until smooth. Cool slightly. Beat in the milk, vanilla and confectioners' sugar until smooth. Frost cake.
