  • 15.25 ounce Chocolate Fudge Cake Mix
  • 1/3 cup vegetable oil
  • 2 large eggs
  • 1/4 cup salted butter
  • 2 cups white chocolate chips
  • 14 ounces sweetened condensed milk


  • Preheat oven to 350⁰F.
  • Prepare a 9X13 cake pan by coating with a non-stick baking spray.
  • Mix together the cake mix, oil, and eggs in a bowl.
  • Press 2/3 of the cake mixture into the bottom of the prepared cake pan. Set the other 1/3 aside until the end.
  • Place the butter, white chocolate chips, and sweetened condensed milk into a small saucepan and heat over medium-low heat, cook, stirring frequently until the white chocolate chips are melted and the mixture is smooth and creamy.
  • Spread the white chocolate chip mixture over the cake batter crust.
  • Crumble the remaining cake batter mixture over the white chocolate chip mixture.
  • Place into the preheated 350⁰F oven and bake for 20 to 25 minutes or until the top cake layer is no longer shiny.
  • Remove from the oven and allow to cool completely before cutting.
