This Butterfinger Cake recipe is an easy poke cake with a rich chocolate cake soaked with caramel and sweetened condensed milk, then piled high with fluffy peanut butter whipped cream and crunchy chopped Butterfingers.
Is there a better poke cake than Butterfinger Cake?
We're talking chocolate cake, gooey caramel, and a peanut butter whipped cream that just work perfectly together–this butterfinger cake is delicious! The best part? It's one of the easiest desserts you will ever make, and can even be made well in advance. It's easy to transport for a potluck or party, and everyone loves it. It's similar to our Better than Sex Cake, but with a butterfinger candy bar twist.

How to make Butterfinger Cake:
Bake Cake: I love using my homemade chocolate cake recipe and baking it in a 9×13″ pan, but you can use Yellow or Vanilla cake, if you prefer! I am passionate about using the ingredients you already have in your pantry, but you could also use a cake mix if you want. Bake according to recipe then let it cool for a few minutes.
Add Sauces: Poke holes in the warm cake then pour caramel sauce and sweetened condensed milk all over the top of the cake. Set aside to cool completely.
Peanut Butter Whipped Cream: Add peanut butter and powdered sugar to a mixing bowl and mix with a hand mixer until smooth. While mixing, slowly pour in whipped cream then whip until stiff peaks form and it holds it's shape. Spread over cake after it has cooled completely.
Refrigerate: Sprinkle crushed butterfingers over the top of the entire cake then refrigerate for at least one hour, or up to one day, before serving.

I originally shared this recipe June 2023. Updated March 2026.
This cake was way easier to make than I expected and turned out so good!!
I made this with the kids for my husband and my anniversary this week! It was pretty fun to have them help, they loved poking the holes in the cake and topping it with all the butterfinger bits. We all enjoyed the cake, it was very refreshing from being chilled in the fridge. It did fill us up quickly with one piece tho.
I made modifications to this recipe using sweetner, keto chocolate cake, SF caramel, SF peanut butter candies and made some keto condensed milk. Was one of the best desserts I have made in a while. After making it the only modifications I can advise is add a tsp to your cake mix. I think it would add a delicious flavor that would combine well with the other flavors. Thank you for posting this recipe I will be using it again!
This was a fun cake to make. The frosting is amazing! Simple to make and not too sweet. I made a gluten free chocolate cake and it worked well. This would be great to bring to a potluck!
“I like it! Delicious!” with two thumbs up from our 11 year old. We made the Hershey’s chocolate cake recipe first & it turned out great! Very simple to throw together in a mixing bowl & hand whisk. We had all ingredients on hand.
Then we made the butterfinger half of this cake. I had a bit of trouble getting the peanut butter & powdered sugar to smooth out. So the whipped cream topping has little bits mixed in. I’m sure it would have been way more flavorful if I had added more pb. So user error on that one. It actually added more texture, so nobody minded. This cake is so delicious & thick & moist. An awesome party cake!
This cake was amazing. I love a moist cake and this cake did not disappoint. I used the cake and caramel recipe provided and both were very simple to make. The hardest part for me was mixing the powder sugar and peanut butter until smooth. It ended up looking like coarse sand. I decided to add a tablespoon of the heavy cream and that smoothed it out.
This cake was super easy to make and very moist ! My kids loved it and definitely will be making again because of the simplicity. Crowd pleaser for sure.
My only suggestion is wait until serving to add the butterfingers on top bc they got very hard in the fridge 🤣
Very good, but a bit too sweet for me! My family loved it. I used the Hershey’s perfectly chocolate cake recipe, and Hershey’s caramel topping. The peanut butter whipped cream is amazing.
My mother found this recipe in a newspaper when I was a little girl. It has been a family favorite. It looks like a lot of work, but so easy to make. I always have the ingredients on hand to make this 😃
Amazing!!!
