The Best Gooey Butterfinger Poke Cake

This recipe couldn’t be easier to make, thanks to my shortcut of doctoring up a boxed cake mix! Just combine the chocolate cake mix, oil, and eggs. Then, you are more than halfway to having a tasty slice of Butterfinger poke cake ready to eat.

Now, the best part of this recipe is the topping. Sweetened condensed milk, peanut butter, and caramel sauce fill up all the holes in the poke cake to add to the rich chocolate flavor. Then, Cool Whip and Butterfinger candy bar pieces finish off the dessert to make every bite truly mouthwatering.

Ingredients to make Butterfinger poke cake.

For the Cake:

  • 1 box (15.25 ounces) chocolate cake mix
  • 1 cup milk – Use whole milk for a full flavor.
  • ⅓ cup oil – Use a neutral oil like canola oil or avocado oil.
  • 3 eggs

For the Topping

  • 1 can (14 ounces) sweetened condensed milk

Directions For How To Make Butterfinger Poke Cake

  1. Prepare: Preheat your oven to 350 degrees Fahrenheit. Then, spray a 9×13 cake pan with cooking spray, and set it aside.
  2. Prepare the cake batter: Whisk all the ingredients for the cake (cake mix and ingredients on the box) in a large bowl until smooth. Pour the mixture into the prepared cake pan, spreading it out evenly.
  3. Bake: Transfer the cake to the oven. Bake for 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
  4. Cool: Set the cake aside to cool completely in the pan.
  5. Prepare the topping: In the meantime, whisk the peanut butter, caramel sauce, and sweetened condensed milk in a separate bowl.
  6. Fill the cake: Use the handle of a wooden spoon to poke holes across the top of the cake. Leave about two inches of space between each hole. Then, pour the peanut butter sauce over the cake, filling the holes. Place it in the fridge to chill for one to two hours.
  7. Top: Spread Cool Whip evenly over the top of the cake. Then, add the chopped Butterfingers, slice, and enjoy cold!

Serving Suggestions

This cake is pretty tasty on its own, but adding a scoop of ice cream to the mix is never a bad idea. You can also skip the Cool Whip, and top the cake with fresh homemade whipped cream instead.

Quick Tip

Make sure not to poke the holes in the cake too close together! Otherwise, the cake will become soggy and is likely to fall apart.
