How to Make Key Lime Pie Rice Krispie Treats

Step One: Prep and grease the pan

I lightly grease an 8×8-inch pan with butter or nonstick spray. Set it aside for easy release.

This is a no-bake Key Lime Pie Rice Krispie Treats moment, so the process stays quick.

Step Two: Melt the butter

In a large pot over low heat, melt 3 tablespoons of unsalted butter until it shimmers softly.

Next, don’t rush this; even heat helps avoid scorching.

Step Three: Melt the marshmallows

Add 4 cups mini marshmallows to the melted butter and stir until melted and smooth.

A gentle swirl keeps them glossy and prevents clumps.

Step Four: Add lime zest, lime juice, white chocolate chips, and salt

Remove the pot from heat, then stir in 1 tablespoon lime zest, 2 tablespoons lime juice, ½ cup white chocolate chips, and ¼ teaspoon salt.

The citrus should be bright but not bitter.

Step Five: Fold in Rice Krispies

Fold in 6 cups of Rice Krispies cereal until evenly coated, using a gentle folding motion to preserve some crunch.

Step Six: Press into the pan

Press the mixture firmly into the prepared 8×8-inch pan using a buttered spatula or clean hands.

Smooth the top for even squares.

Step Seven: Optional topping and chill

If you like, sprinkle crushed graham crackers over the top and press them in lightly.

Chill until set, about 20–30 minutes.

Once firm, lift out and cut into 12 squares.

Tips for Success with Key Lime Pie Rice Krispie Treats

Quick tips

• I use fresh lime juice for brightness; bottled juice dulls the zing.
• I lightly grease the pan and spatula to prevent sticking when pressing.
• I cool slightly before slicing for cleaner edges; a quick chill helps.
• If I want a paler finish, I skip the graham topping completely.
• I store Key Lime Pie Rice Krispie Treats in an airtight container for up to 3 days, or freeze for longer storage.
