Preheat your oven according to the instructions on the cake mix package. Grease a 9×13-inch baking pan and prepare the cake batter as directed on the box. Bake until a toothpick inserted in the center comes out clean.

Once the cake has cooled for about 5 minutes, take the handle of a wooden spoon and poke holes evenly across the surface. These holes will allow the condensed milk and caramel to seep into the cake, making it extra moist and flavorful.

Pour the sweetened condensed milk slowly and evenly over the cake, letting it sink into the holes. Follow with a generous drizzle of caramel topping, spreading it out evenly with a spoon or spatula. Allow the cake to cool completely before moving to the next step.

Spread the Cool Whip over the cake in a thick, even layer. This light topping balances the richness of the cake and fillings.

Chop Snickers bars or Reese’s cups into small bite-sized pieces and sprinkle generously over the top. For added flair, drizzle with a little extra caramel.

Refrigerate for at least an hour before serving. This helps the flavors meld together and makes slicing easier.
