Butterscotch Toffee Rice Chex Treats

Line a 9x13-inch baking pan with foil and spray the bottom and sides of the pan with baking spray. In a large pot on the stovetop over medium-high heat, add the butter. Melt the butter. Once the butter is melted, add the mini marshmallows, reserving one cup of marshmallows. Stir constantly until marshmallows are completely melted and the butter and marshmallows are completely incorporated.

Remove the pan from the heat. Add the butterscotch chips and white chocolate chips immediately and stir until melted completely into the marshmallow-butter mixture. Stir in the vanilla extract and salt. Stir in the Rice Chex cereal one cup at a time. Fold in the remaining cup of mini marshmallows and toffee. Stir until incorporated.

Pour mixture out into prepared pan and sprinkle the semi-sweet chocolate chips on top. Let cereal treats cool and set completely before cutting into desired sized squares.
