  • Total Time
    Prep: 20 min. Bake: 35 min. + cooling
  • Makes
    20 servings


  • 1 cup butter, softened
  • 2 cups sugar
  • 4 large eggs, room temperature
  • 1-1/2 cups self-rising flour
  • 1/2 cup baking cocoa
  • 1 cup chopped pecans
  • 1 jar (7 ounces) marshmallow creme
  • 1/2 cup butter, softened
  • 3-3/4 cups confectioners' sugar
  • 3 tablespoons baking cocoa
  • 1 tablespoon vanilla extract
  • 4 to 5 tablespoons 2% milk
  • 1 cup chopped pecans


  • In a large bowl, cream butter and sugar until light and fluffy, 5-7 minutes. Add eggs, 1 at a time, beating well after each addition. Combine flour and cocoa; gradually add to creamed mixture until blended. Fold in the pecans.
  • Transfer to a greased 13x9-in. baking pan. Bake at 350° until a toothpick inserted in the center comes out clean, 35-40 minutes. Cool for 3 minutes (cake will fall in the center). Spoon the marshmallow creme over cake; carefully spread to cover top. Cool completely.
  • For frosting, in a small bowl, cream butter and confectioners' sugar until light and fluffy, 5-7 minutes. Beat in the cocoa, vanilla and enough milk to achieve frosting consistency. Fold in pecans. Spread over marshmallow creme layer. Store in the refrigerator.

As a substitute for 1-1/2 cups self-rising flour, place 2-1/4 teaspoons baking powder and 3/4 teaspoon salt in a measuring cup. Add all-purpose flour to measure 1 cup. Combine with an additional 1/2 cup all-purpose flour.

    Oh my goodness! This was amazing! I even messed up on the frosting the first time, and it was still so good! We didn’t have Marshmello fluff, so I ended up making my own marshmallow frosting, and we didn’t have powdered sugar so I used regular sugar. That didn’t work as well as I hoped, and I don’t recommend that. Even then, it was delicious! I can’t wait to make it again with the right ingredients!

    My mom used to bake this cake when we were all young and still living at home. Now, that we are grown, I have made this same cake which we called "the Mud cake" and people seem to really like it.

    This is a yummy dessert. This is one of the first recipes my teenager learned to make and, unfortunately for my waist line, she wants to make it frequently!
