Key Lime Pie Rice Krispie Treats

Spray a 9×13-inch baking dish with non-stick baking spray. Set aside.

In a large bowl stir together the crispy rice cereal and 5-6 chopped graham crackers, set aside.

In a large sauce pan, melt butter over low heat. Once butter has melted, stir in 8 cups marshmallows. Continue cooking over low heat, stirring constantly, until marshmallows and butter are fully melted together.

Remove from heat and stir the lime zest and juice from 4 key limes (approximately 1 1/2 tablespoons juice and 2 teaspoons of zest) into melted marshmallow mixture. Stir cereal/graham cracker mixture and remaining 2 cups of marshmallows into melted marshmallows mixture, stirring until well combined. Note: It is ok if the additional 2 cups of marshmallows only partially melt.

Using a rubber spatula, sprayed with non-stick cooking spray, spread marshmallow covered cereal treats evenly into prepared 9×13-inch baking dish. Quickly press remaining chopped graham crackers onto the top of the prepared treats.

In a small microwave safe bowl, combine white chocolate and oil. Microwave for 30 seconds. Remove melted chocolate from microwave and stir. Return to microwave and microwave for an additional 30 seconds to continue melting, if needed. Stir the zest from 1-2 key limes (approximately 1 teaspoon of zest) into the white chocolate mixture. Drizzle melted white chocolate evenly over the top of the prepared cereal treats.

Allow treats to sit for at least 30 minutes to 1 hour before slicing into bars. Store cereal treats in an air tight container for 4-5 days.
