Introduction

Lime Krispie Treats are a zesty twist on the classic marshmallow cereal bar. Bursting with fresh key lime flavor and a smooth white chocolate drizzle, these treats are perfect for a refreshing snack or party dessert.

The image shows three square-shaped rice crispy treats with two main layers. The bottom layer is made of light golden crispy rice cereal mixed with a pale green element, giving it a slightly speckled look inside. The top layer is a thick, smooth white cream evenly spread over the crispy base. On top of the white cream, there are small green and light tan sprinkles scattered evenly, adding texture and color contrast. The treats are placed on a white marbled surface, and lime wedges are visible around the treats, giving a fresh and zesty feel to the scene. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

5 cups Rice Krispies cereal
10 cups mini marshmallows
5 tablespoons unsalted butter
1/2 cup key lime juice (fresh or bottled)
2 tablespoons key lime zest
1 cup graham cracker crumbs
1 cup white chocolate chips
1/2 teaspoon coconut oil (for smooth chocolate drizzle)
Optional add-ins:
- 1/2 cup coconut flakes
- 1/4 cup crushed nuts
- A few drops green food coloring

Instructions

Step 1: In a large saucepan, melt the butter over low heat. Add the mini marshmallows and stir continuously until the mixture is smooth and melted.
Step 2: Stir in the key lime juice and key lime zest until fully combined and fragrant.
Step 3: Pour the melted marshmallow mixture over the Rice Krispies cereal in a large bowl. Gently fold together until all the cereal is evenly coated.
Step 4: Line a baking dish with parchment paper. Spread the mixture evenly into the dish and press gently without over-packing to keep the treats light and chewy.
Step 5: Sprinkle the graham cracker crumbs evenly over the top of the mixture.
Step 6: Melt the white chocolate chips together with the coconut oil using a microwave or double boiler. Drizzle the melted chocolate over the top of the treats.
Step 7: Refrigerate for about 30 minutes to set the chocolate and allow the treats to firm up.
Step 8: Once set, slice into squares and serve.

Tips & Variations

Add 1/2 cup coconut flakes or 1/4 cup crushed nuts into the cereal mixture for extra texture and flavor.
A few drops of green food coloring can be added with the marshmallow mixture to enhance the lime theme visually.
Press the mixture lightly into the pan to keep the treats chewy rather than dense.
Use fresh key limes for the best bright flavor, but bottled juice works well if fresh is unavailable.

Storage

Store Lime Krispie Treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them refrigerated for up to a week. Before serving refrigerated treats, let them come to room temperature for the best texture. Avoid freezing as it may affect the marshmallow’s chewiness.

FAQs

Can I use regular lime juice instead of key lime juice?

Yes, regular lime juice can be used as a substitute, though key lime juice has a distinct tartness that gives the treats a unique flavor. Regular lime will still provide a fresh citrus note.

How do I melt the white chocolate chips without burning them?

Melt white chocolate chips gently by microwaving in short 20-second bursts, stirring between each until smooth. Alternatively, melt over a double boiler on low heat, stirring constantly to prevent scorching.
