Ingredients
Scale
Main Ingredients
- 5 cups crispy rice cereal
- 8 whole graham crackers, chopped and divided
- 5 tablespoons unsalted butter
- 10 cups miniature marshmallows, divided
- 6 key limes, juiced and zested (divided as per recipe steps)
- 4 ounces white chocolate or vanilla almond bark
- ½ teaspoon coconut oil or vegetable oil
Instructions
- Prepare the Dish: Spray a 9×13-inch baking dish with non-stick baking spray and set it aside for later.
- Mix Cereal and Graham Crackers: In a large bowl, stir together the 5 cups of crispy rice cereal and about 5-6 chopped graham crackers; set this mixture aside.
- Melt Butter and Marshmallows: In a large saucepan over low heat, melt the 5 tablespoons of unsalted butter. Once melted, add 8 cups of miniature marshmallows and stir continuously until the marshmallows and butter form a smooth, fully melted mixture.
- Add Lime and Combine: Remove the saucepan from heat and stir in the zest and juice from 4 key limes (about 1½ tablespoons juice and 2 teaspoons zest). Then fold in the cereal and graham cracker mixture along with the remaining 2 cups of marshmallows, stirring until everything is well combined. It’s fine if these last marshmallows are only partially melted.
- Press Into Pan and Top: Using a rubber spatula lightly sprayed with non-stick spray, evenly spread the marshmallow-coated cereal mixture into the prepared baking dish. Quickly press the remaining chopped graham crackers onto the top of the treats for added crunch.
- Melt White Chocolate and Add Zest: In a small microwave-safe bowl, combine 4 ounces of white chocolate and ½ teaspoon of coconut or vegetable oil. Microwave for 30 seconds, stir, then microwave for another 30 seconds if needed until completely melted. Stir in zest from 1-2 key limes (approximately 1 teaspoon) into the melted white chocolate.
- Drizzle Chocolate and Set: Drizzle the white chocolate mixture evenly over the top of the cereal treats in the pan. Let the treats sit at room temperature for at least 30 minutes to 1 hour to firm up before slicing.
- Store: Store the Key Lime Pie Rice Krispie Treats in an airtight container for up to 4-5 days for best freshness.
Notes
- Use fresh key limes for the best authentic tangy flavor, but bottled key lime juice can be substituted in a pinch.
- If white chocolate is too thick, add a little more coconut or vegetable oil to thin it for easier drizzling.
- Pressing the graham crackers on top while the mixture is still warm helps them stick better.
- These treats are best enjoyed within a few days for optimal texture and flavor.
- Use non-stick spray on your spatula to prevent sticking when spreading the mixture.
