Chocolate Butterfinger Cake

If you love Butterfinger candy bars as much as we do, you’re going to flip over this cake. It has the same peanut butter and milk chocolate flavors, but in a decadent sheet cake form! It starts with a made-from-scratch chocolate cake that’s loaded with crumbled Butterfingers, then frosted with a store-bought sweet vanilla frosting.

The Butterfinger goodness doesn’t stop there though. We top it off with a drizzle of chocolate frosting and sprinkle it with even more crispy candy bits. Each bite has the perfect blend of rich chocolate cake, creamy frosting, and that classic Butterfinger crunch.

Why We Love This Recipe

  • Easy dessert: Though you make the cake from scratch, it’s super easy with just a few simple steps.
  • Decadent chocolate & peanut butter combination: This cake is loaded with peanut butter and chocolate Butterfinger flavors. Is there any better dessert combination than peanut butter and chocolate?
  • Potluck favorite: Because it’s baked and stored in a baking dish, this is a great recipe to take to potlucks, office parties, or other gatherings.
  • Customizable: You can easily swap the flavor of the cake, the frosting or even the toppings to make a different dessert each time.

Ingredients Needed

A list of ingredients for a Butterfinger cake
  • Flour
  • Sugar
  • Cocoa
  • Salt
  • Baking soda
  • Buttermilk
  • Vegetable oil
  • Eggs
  • Vanilla
  • Butterfingers (you can use the candy bars or the packaged bits)
  • Vanilla icing
  • Chocolate icing

How To Make Butterfinger Cake

Step 1. Mix together your flour, cocoa, baking soda, and salt. Add the sugar and mix until well combined.

Step 2. Add the buttermilk, oil, vanilla, and eggs. Beat, using a mixer, just until well combined and smooth.

Step 3. Fold the chopped Butterfinger candy bar into the batter.

Tip: You can make the Butterfinger pieces any size you want, though I usually crush them for the batter and chop them for the topping. This just gives the cake extra texture.

Step 4. Pour the cake batter into a well greased 9×13 baking dish.

Tip: You can also use an 8×8 or 9×9 pan but you’ll have to adjust the baking time. If you use a pan larger than a 9×13, you should double the batter recipe. To make sure the cake is done, insert a toothpick in the center of the cake to see if comes out clean

Step 5. Bake at 350 degrees for 20 to 30 minutes, or until a toothpick comes out clean.

Step 6. Allow cake to cool completely in the cake pan. Frost the top of the cake with vanilla icing.

Step 7. Top with the chopped or crushed butterfingers.

Step 8. Place your chocolate icing in the microwave for one minute. Stir well, and pour into a piping bag. Cut a small tip off and drizzle over the cooled cake.

How to Store Leftovers

To keep this delicious Butterfinger cake fresh, store it in an airtight container or cover it with plastic wrap. Pop the cake in the fridge when not serving it. It will stay fresh and moist for about 3-4 days.

Before serving, let the cake sit out for about 15 minutes to let the frosting soften slightly.

Variations

  • Cake: You can use a box mix if you prefer. You can also try other flavors like chocolate cake mix, devil’s food cake mix or yellow cake mix.
  • Drizzle: We used chocolate frosting for the drizzle but it’s also delicious with the caramel topping that you use for ice cream. Give it even more peanut butter flavor by heating peanut butter in the microwave and drizzling it over the top.
  • Frosting: We like to keep things simple with store-bought frosting but you can also give it a tangy twist with homemade cream cheese frosting.
  • Candy topping: This cake is topped with Butterfinger bars, but you can use any kind of chocolate candy. We also love making this recipe with Heath Bars and Reese’s Peanut Butter Cups.

Butterfinger Cake FAQs

What do Butterfingers taste like?

Butterfingers have a buttery, crispy, candy filling covered in smooth milk chocolate. If you love the taste of peanut butter and chocolate together, you’re going to love these!

Can I freeze Butterfinger cake?

Sure, If you want to freeze this cake, start by placing it uncovered in the freezer for about an hour, or until the frosting firms up. Then cover the dish tightly with plastic wrap, then with a layer of foil. It should stay fresh for up to a month of two. Let it thaw overnight in the fridge before serving.

Can I turn this recipe into a Butterfinger poke cake?

You can! Just gently poke holes in the top of the cake with the end of a wooden spoon. Pour sweetened condensed milk or caramel sauce over the top. I would recommend frosting this version with whipped cream instead of the frosting.

      If Walmart doesn’t have the cake pans I’ll bet that Bed,Bath/and Beyond would. Seriously they have an interesting collection of cookware.
