1 (15.25 ounce) package devil’s food cake mix
⅔ cup water
½ cup oil
2 large eggs
1 (14 ounce) can sweetened condensed milk
1 (12 ounce) jar hot fudge dessert topping
1 (12 ounce) jar caramel dessert topping
1 (16 ounce) package frozen whipped topping (such as Cool Whip®), thawed

Directions

Preheat oven to 350°F. Grease a 9×13-inch baking pan with spray or butter, and line with parchment paper.
In a large bowl, whisk together cake mix, water, oil, and eggs until smooth. Pour into prepared pan.
Bake for 28–30 minutes or until a toothpick comes out clean.
Let cake cool for 5 minutes, then poke holes all over the top with the handle of a wooden spoon, knife, or skewer.
Pour sweetened condensed milk evenly over the cake. Warm hot fudge and caramel slightly if too thick, then pour both over the cake. Let cool completely for about 1 hour.
Spread whipped topping evenly over cooled cake.
Sprinkle crushed Butterfinger candy bars on top.
Refrigerate for at least 4 hours before serving.

Variations

Use peanut butter cups instead of Butterfinger bars for a different flavor.
Swap devil’s food cake for yellow cake or chocolate fudge cake.
Add a drizzle of extra caramel or chocolate syrup before serving.
Use homemade whipped cream instead of frozen whipped topping.
Try topping with chopped peanuts for added crunch.

Storage/Reheating

Store leftovers in the refrigerator, covered, for up to 4 days.
This cake should not be frozen, as the texture of the whipped topping and candy bars won’t hold up well.
Serve cold, straight from the fridge, for the best flavor and consistency.
