BUTTERFINGER RICE KRISPIES TREATS
INGREDIENTS
- 6 cups Rice Krispies cereal
- 3 tablespoons butter
- 1 (10 oz) package miniature marshmallows (or 7 oz marshmallow creme)
- 1–2 cups Butterfinger baking bits or crushed Butterfinger candy bars
DIRECTIONS
- Lightly coat a 9 x 13-inch baking dish with cooking spray or line it with parchment paper.
- In a large microwave-safe bowl, combine the butter and marshmallows. Microwave on HIGH for 2 minutes. Stir, then continue microwaving for 1 additional minute, or until the marshmallows are completely melted. Stir until smooth.
- Fold in the Rice Krispies cereal and Butterfinger baking bits, stirring until everything is evenly coated.
- Transfer the mixture to the prepared baking dish. Using a buttered spatula or a piece of wax paper or parchment paper, gently press the mixture into an even layer. Avoid pressing too firmly, which can make the treats dense.
- Let cool completely before cutting into squares.
- Butterfinger baking bits work great, but crushed Butterfinger candy bars are just as delicious.
- Add more or less Butterfinger depending on how much peanut butter crunch you want.
- Store in an airtight container at room temperature for up to 3 days.
- These treats are best enjoyed the day they are made.
