  • 6 3 Musketeer Candy Bars regular size
  • 1 3/4 sticks butter softened
  • 2 cups flour
  • 1 1/2 cups sugar
  • 3/4 cup milk
  • 3 eggs
  • 1 teaspoon baking soda
  • 1 1/2 teaspoons vanilla


  • 4 3 Muskeeter Bars regular size
  • 1/2 cup + 2 tablespoons butter
  • 1 teaspoon vanilla
  • 1 cup powdered sugar
  • 1 to 2 tablespoons milk optional



  • I used a greased 9 x 13 pan, a bundt pan will also work, it will just take longer to bake.
  • Melt together butter and 3 Musketeers bars in a saucepan over medium heat. Stir often to avoid burning.
  • Measure remaining ingredients and have ready in a mixing bowl. Add melted candy bars. Mix well.
  • Bake at 300 degrees for 45 to 55 minutes. Prepare icing; spread over cake


  • Melt together butter and 3 Musketeers candy bars in a saucepan over medium heat. Stir often to avoid burning
  • Add vanilla and powdered sugar; stir until smooth. If desired, add milk to get to spreading consistency. Spread over cake.  While the icing was warm I gently tilted cake in each direction to get full coverage of icing.


This creamy chocolate cake is one of our favorites because it calls for real 3 Musketeers candy bars!  Here are some tips for a delicious cake:
  • Have all ingredients measured and ready before beginning each portion of the recipe.
  • Don’t rush the melting of the candy bars.  Low heat to medium-low heat and steady stirring wins the melting race.  It would be a shame to burn the candy bars!
  • Pour warm icing on a warm cake.
  • Cover with plastic wrap to maintain maximum moistness.
  • Cool before serving.
