In the words of Bart Simpson, "Don't lay a finger on my Butterfinger". Or for the purposes of this blog post, Butterfinger cake! We all know that I am a lover of anything peanut butter and chocolate as aforementioned, but their is just something about the texture and flavor of a Butterfinger bar. It's so crunchy, peanut buttery and chocolatey! One bite, just melts in your mouth. Nonetheless, it was time I added it to one of my desserts!
This candy bar brings me back to the late 80's and early 90's when the Simpsons were big. However, we weren't allowed to watch them on a regular because of the vulgarity! Wow, if my parents thought the Simpsons was a vulgar show, fast forward to today! Nevertheless, the Butterfinger commercial was huge for several years and really helped Bart become a household name!
A peanut butter three layer cake infused with crushed Butterfinger, layered with Butterfinger buttercream frosting, and then topped with additional crushed Butterfinger. A pure Butterfinger explosion all in one cake, you can't go wrong! Can you tell my obsession at all?

How to make a Butterfinger cake
For the cake layers
First, preheat the oven to 350 degrees. Grease and layer three 8 inch cake pans with parchment circles and set aside. Take one Butterfinger candy bar and crush it down to crumbles in a plastic bag and set aside.
Second, with an electric mixer, cream together the softened butter, both sugars, and creamy peanut butter together until light and fluffy. This can take 3-4 minutes. Next, add the sour cream and vanilla extract until batter is well combined. Add in eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed.
Third, in another bowl, whisk and combine all the dry ingredients together. In a measuring cup, combine the milk and water.
Fourth, add about ⅓ of the dry ingredients to the batter and mix until well combined. Alternate adding dry ingredients and milk mixture to the batter, starting and ending with dry ingredients. Fold in the crushed Butterfinger bar to the batter.
Fifth, divide the batter evenly among cake pans. Baking for 27-29 minutes or until toothpick inserted into the center comes out with a few crumbs. Remove from oven and after a couple of minutes transfer to cooling rack to complete cooling process.
Making the frosting
First, combine all the ingredients into a bowl of a stand mixer fitted with a paddle attachment. Mix on low until well blended and you have reached desired consistency of frosting. Set aside.
Assembly of cake
First, using a serrated knife, remove the domes from the tops of each cake until they are level and flat. Place the first cake layer on a cake board. Spread about 1 cup of frosting on top of cake layer and spread evenly.
Second, add the second layer on top and add another cup of frosting on that layer and spread evenly. Top the cake with the remaining layer of cake. Frost the entire cake to create a crumb coat. Put in fridge for 15 minutes.
Third, remove cake from fridge and add the rest of the frosting all over the the cake.
Lastly, add additional crushed Butterfinger on top of the cake. Serve and enjoy!
