Why this recipe works

If you’ve never slowly cooked a cake in the crockpot, then you’ll soon find out that it’s reason number one for why this recipe works. You’ll use box cake mix so there’s nothing being made from scratch. Instead of slicing the cake like you normally would from being baked in the oven, the moist cake is spooned out.

This butter fingers cake recipe also takes minimal prep. Besides cutting up the mini Butterfingers, the process is literally a mix, dump, and go. You’ll have a delicious cake ready to serve within 2 hours.

Last but not least, this dessert cuisine uses ingredients that are considered pantry staples. Whatever you don’t have on hand can be conveniently picked up at your local grocery store.

Is this similar to a poke cake?

This particular recipe doesn’t require you to poke holes in it, but you certainly can. To make this a “poke cake,” simply poke holes in the cake once it has finished cooking. Then, continue with the remaining instructions for the cake. In the end, you’ll have a Butterfinger poke cake!

Variations

  • Chocolate Cake – For a slightly different taste (and look) to your dessert, try using chocolate cake mix instead of yellow cake mix. You’ll then have a moist chocolate cake base. You can also get a little extra wild by trying devils food cake mix.
  • Change the Topping – Caramel sauce, caramel topping, cream cheese whipped topping, cream cheese frosting, and milk chocolate syrup are a few different toppings you can play around with.
  • Different Candy Bars – Although this Butterfinger cake recipe calls for Butterfinger candy bars, you can experiment with different ones (Snickers, Reese’s, Heath bars, etc.).

    How do you think a gluten free cake mix will work?!

    1. Sarah Olson says:

      You will want to use the liquid amounts on the back of the gluten free mix for it to work correctly, but other than that, should be fine.

  2. Debbie says:

    What size crock pot?

    1. Sarah Olson says:

      6-quart oval.

  3. Anonymous says:

    Can this be made in the oven?

    1. Sarah Olson says:

      Yes! Follow the directions on the box cake mix.

    Looks delicious! Could a crockpot liner be used so that the cake could be lifted out and placed on a cake plate or carrier?

    1. Sarah Olson says:

      Yes that will work great. Though youโ€™ll need to cool it a bit first.

  5. Shannon says:

    Looks awesome! Do you think doubling the recipe to serve more would still work?

    1. Sarah Olson says:

      I don’t think it will set in the middle before the edges burn.
