Butterfinger Desserts

Butterfinger desserts are some of my favorites. I’ve made Butterfinger Lush, Butterfinger Cheesecake, No-Bake Butterfinger Oatmeal Cookies, and Butterfinger Poke Cake. So many delicious butterfinger recipes.

This easy slow cooker dessert has chopped butterfinger candies in the cake batter and more chopped butterfingers on top for a little crunch.

Ingredients Needed

  • 1 Box Yellow Cake Mix– I use Duncan Hines or Betty Crocker.
  • 3 Large Eggs
  • Creamy Peanut Butter– you can use crunchy if you prefer.
  • Butter– I use salted, but you can use unsalted.
  • Butterfinger Candies– any size butterfinger candy works. You will need about 2/3 of a cup chopped for the cake batter and more for on top.
  • Milk– to thin the glaze. Half-and-half can be used instead.
  • Powdered Sugar– to add sweetness to the glaze.
  • Fudge Sauce– I like to drizzle fudge sauce on top for extra chocolate flavor, but you can leave it off.

Cooking Time

The cooking time is an estimate because different slow cookers cook at very different rates and newer models get hotter than older models. It could be done in less time or it may take longer.
