Inspired by the candy bar, this Mounds cake combines chocolate and coconut into a luscious layer cake. The recipe is simplified with a chocolate cake mix so you can focus on creating the coconut filling and thin chocolate icing. The cake can be split to make four layers creating a more dramatic presentation, or baked in three 8-inch cake pans for a three-layer cake.

While the cake is baking and cooling, you can make the filling and icing. Evaporated milk, sugar, and marshmallows are cooked until melted, and then the frozen coconut is mixed in to make the filling. The icing comes together easily on the stovetop as well, starting by simmering the heavy cream and then stirring in the vanilla and chocolate chips, creating a smooth and pourable rich chocolate icing.

Once the cake is cooled and cut, the coconut filling is spread in between the layers and the icing is poured over top, making for a cake special enough for birthdays, Christmas, and parties.


  • For the Cake:
  • 1 box chocolate or chocolate fudge cake mix (plus oil, eggs, and water as directed)
  • For the Filling:
  • 1 1/2 cups evaporated milk
  • 1 cup sugar (granulated)
  • 16 large marshmallows
  • 14 ounces frozen coconut
  • For the Chocolate Ganache Icing:
  • 2 cups heavy cream
  • 1 1/2 teaspoons vanilla extract
  • 2 cups semisweet chocolate chips
  • Optional: sweetened coconut (toasted, if desired)
