Why I love this recipe:

  • Easy – This Butterfinger poke cake may look intimidating, but it couldn’t be more simple to make! Baked in a 9×13 pan, this is a dessert anyone can make.
  • Delicious – This cake is decadent with the chocolate cake, caramel sauce, and sweetened condensed milk, but the peanut butter whipped cream lightens and balances it perfectly.
  • Unique – Wow your friends with an easy butterfinger cake they have never tried before! I get compliments on this cake every time I make it!

Ingredients Needed:

All the ingredients needed to make the best Butterfinger Cake: chocolate cake, crushed butterfingers, sweetened condensed milk, caramel sauce, peanut butter, heavy cream, and powdered sugar.

How to make Butterfinger Cake:

Make Cake: I make my homemade chocolate cake recipe and bake the cake in a 9×13” pan (you could use a cake mix chocolate cake if you want). Allow cake to cool for a few minutes, then poke holes in it with a fork or wooden skewer.

Add Sauces: Pour caramel sauce and sweetened condensed milk all over the top of the cake. Set aside to cool completely.

Make Peanut Butter Whipped Cream: Add the peanut butter and powdered sugar to a mixing bowl and mix until smooth. While mixing, slowly pour in whipped cream. Whip until stiff peaks form, and it holds its shape. Spread all over cooled cake.

Frost Cake: Sprinkle crushed butterfingers on top. Refrigerate for at least 1 hour, or up to one day, before serving.

Make Ahead and Freezing Instructions:

To Make Ahead: Make the chocolate cake up to 1 week ahead of time. Allow it to cool completely, cover it well, and store it in the freezer. Allow it to thaw overnight in the refrigerator (or leave it at room temperature for a couple hours) and then continue with step 2, poking holes in the cake. The homemade caramel sauce can be made several days in advance to save time. It can be poured on the cake warm or cold.

To Freeze: Allow the cake to cool completely.  Cover well and freeze for 2 months. Thaw overnight in the refrigerator. Add toppings before serving.

    Forgot to put five stars on the previous comment! This cake was gone in two days. I think everyone in our family ate it for or with every meal until it was down to one piece left and we had to have a dance off for who got the last piece. Thanks for all the family fun and deliciousness.

    This was delicious! Even my husband (who doesn’t generally like cake) enjoyed a piece. I did have trouble mixing the peanut butter and powdered sugar smoothly. I was concerned as looked like it was dotted throughout the whipped cream rather than incorporated. After the cake chilled, though, it wasn’t even noticable. I enjoy the flavor combination and the crunch of candy on top.

  3. 5 stars
    This was a really good cake. I have made the chocolate cake part a few times. It is the best base chocolate cake you can find.

  4. 4 stars
    Delicious and really easy to make! I’ve been eating it for breakfast everyday since I can’t wait to eat it after dinner!

  5. 5 stars
    Super indulgent and fun cake! The butterfingers give it the perfect peanut butter crunch. Since I made my cake from scratch, I dialed down the sugar just a bit to account for all the sweetness in the toppings and it was just right.

    Butterfingers. I want to marry them. Lol

    Loved this recipe. Who knew it would be just as delicious as the candy. This one is a keeper. ❤️
