Equipment

Ingredients

  • 1 cup flour
  • 1 cup sugar
  • 6 tablespoons cocoa
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 2 eggs
  • 2 teaspoons vanilla extract
  • 1 cup processed Butterfinger candy bars about 7 mini bars
  • 16 ounces vanilla icing 1 container
  • 7 mini Butterfingers bars crumbled
  • 8 ounces chocolate icing

Instructions

  • Mix flour, cocoa, baking soda, and salt in a large mixing bowl. Add the sugar and mix until well combined.
  • Add the buttermilk, oil, vanilla, and eggs. Beat, using a mixer, just until well combined and smooth.
  • Fold the chopped Butterfinger candy bar into the batter.
  • Pour the cake batter into a well greased 9x13 baking dish.
  • Bake at 350 degrees for 20 to 30 minutes, or until a toothpick comes out clean.
  • Allow cake to cool completely in the cake pan. Frost the top of the cake with vanilla icing.
  • Top with the chopped or crushed butterfingers.
  • 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. Serve and enjoy!

Notes

  • If you're short on time, or just like a super easy recipe, you can make this with a box cake mix instead.
  • 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.
  • You can also use an 8x8 or 9x9 pan but you'll have to adjust the baking time. If you use a pan larger than a 9x13, 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
  • This recipe makes 8 large slices or 10 regular size slices of cake.
