Ingredients

Cake

  • 1 box chocolate cake mix
  • 1 cup whole milk
  • 1/2 cup canola oil
  • 3 large eggs

Toppings

  • 1 can sweetened condensed milk
  • 1 jar caramel dessert topping
  • 1 container frozen whipped topping thawed
  • 2 Butterfinger candy bars crushed
  • Additional caramel sauce for garnish, optional

Instructions

  • Preheat the oven according to the temperature listed on the chocolate cake mix package.
  • Lightly grease a 9x13-inch baking dish with nonstick cooking spray.
  • Place the chocolate cake mix in a large mixing bowl.
  • Add the whole milk, canola oil, and eggs.
  • Mix until the batter is smooth and fully combined.
  • Pour the batter into the prepared baking dish.
  • Spread the batter evenly in the dish.
  • Bake according to the instructions on the cake mix package, or until a toothpick inserted into the center comes out clean.
  • While the cake is baking, combine the sweetened condensed milk and caramel dessert topping in a medium mixing bowl.
  • Stir until the mixture is smooth and evenly combined.
  • Remove the baked cake from the oven.
  • While the cake is still hot, use the handle of a wooden spoon to poke holes across the surface of the cake, spacing them about 1 inch apart and making them approximately 1 inch deep.
  • Pour the sweetened condensed milk and caramel mixture evenly over the hot cake.
  • Spread the mixture gently over the surface, allowing it to fill as many holes as possible.
  • Allow the cake to cool completely.
  • Once the cake has cooled, spread the thawed whipped topping evenly over the entire surface.
  • Sprinkle the crushed Butterfinger candy bars evenly over the whipped topping.
  • Drizzle with additional caramel sauce, if desired.
  • Refrigerate the cake until ready to serve.
  • Slice and serve chilled.
