Recipe Ingredients

  • Devil’s Food Cake Mix (the cheaper the better, we want a good old coarse cake).
  • Can of sweetened condensed milk
  • Caramel topping
  • Cool Whip
  • Butterfinger candy bar

How To Make Butterfinger Cake Step by Step

Bake cake according to instructions and then poke holes.

Prepare cake mix and bake cake according to the package directions.

When it comes out, poke holes all in it with a fork or the handle of a wooden spoon, just like we did on the pineapple poke cake. Don’t stop until it looks like a swarm of four toothed mosquitoes attacked!


Combine condensed milk and caramel topping.Pour the entire can of sweetened condensed milk into a bowl, add the caramel topping, and stir to combine.

Smear condensed milk mixture over the cake.

How to Make it a Poke Cake

While the cake is still hot, pour the caramel/condensed milk all over the top and spread it around evenly. Then let it soak in. Oh my good lord almighty, this is gonna be good.

Crumble Butterfinger candy bar.

Chop up your Butterfinger bar and crush it like above.

Add Butterfinger crumbs to cake.

Sprinkle 3/4 of the chopped Butterfinger crumbs over the cake. Now let it cool a bit. I stick mine in the fridge at this point.

Top Butterfinger cake with Cool Whip and Butterfinger crumbs.

Once it is cooled, top with the whole thing of whipped cream and remaining Butterfinger bits. Refrigerate.

Now, you can eat this now but it really and truly should get good and cold before you do.

Alright so go ahead and eat a bit now if you have to, but just promise me you’ll have another slice once it cools. You may even need to have two or three slices once it is good and cold so you can make sure you are tasting it fully as it would be quite rude to serve something to others which you have not adequately tasted – for their own good, of course.


  • Because of the whipped topping, you must store any Butterfinger poke cake leftovers covered in the fridge. They’ll last for up to 3 days.
  • If you want to store leftovers in the freezer, I recommend freezing the cake without the whipped topping and candy crumbs for best results. Store the cake in the freezer in an airtight container for up to 3 months.

Recipe Notes

  • Instead of the chocolate cake mix, you could use a yellow cake mix or fudge marble cake mix instead.
  • Alternatively, substitute the Butterfinger candy bar for your favorite, whether that’s Snickers, KitKat, or Twix. You could even use a combination of your favorites. Just chop them up and sprinkle them on top!
  • If you want to add an extra indulgence to your cake, drizzle it with peanut butter, extra caramel sauce, or some chocolate syrup.
  • The Canadian and UK version of a Butterfinger bar is a Wunderbar. 

Recipe FAQs

What is a poke cake?

A poke cake is a cake that is poked full of holes to allow icing, Jell-o, pudding, or in this case, sweetened condensed milk and caramel, to slide on through. By “poking” the top of the freshly baked cake the syrup or cream runs down into those holes, settles in there real good, and enhances the taste of the cake. Poke cakes gained popularity around the 70s when cake mixes were introduced.

What is the difference between Butterfinger cake and Better Than Anything cake?

The main difference between these two cakes is that Better Than Anything cake uses Heath bars rather than Butterfinger candy bars. But the rest of the recipe is basically the same.

Can I make this poke cake in advance?

Yes, if you want to assemble the entire Butterfinger cake recipe ahead of time, you can store it in the fridge for up to 3 days. However, the Butterfinger crumbs will lose their crunch after a day or so. Another option is to make the cake ahead of time and then add the toppings before serving.
