Instant Pot Butterfinger Cake

Butterfinger cake is a scrumptious dessert, perfect for birthdays or any occasion. It’s a huge crowd-pleaser you’ll be asked for again and again. The irresistible combination of sweet, gooey cake and crispity, cruchity candy topping will be an addictive treat you will love.

Soaking the cooked cake in the milk-caramel sauce gives it a texture almost like a Mexican tres leches cake–moist and sweet. Be sure to let the caramel soak in fully for maximum effect.

Put Butterfingers in a quart-size bag and freeze for 15 minutes, then crush with a mallet. If you don’t chill before you crush, the chocolate will turn into a blob instead of breaking. Refrigerate the crumbles until ready to use.

Pro tip: Depending on the size of pan you use for this recipe, may have batter left over. Pour the extra batter into a small, shallow, well-greased bowl and microwave on low for 1.5 – 2.5 minutes until center is set. Now you have a snack while you are waiting for the rest of the cake. Cook’s treat!
