Key Lime Pie Rice Krispie Treats Ingredients • Dive into this delightful recipe and discover what makes these treats so special! For the Base Rice Krispies Cereal – Provides the crunchy base; substitute with puffed rice or gluten-free cereal for variety. Marshmallows – Create that beloved chewy consistency; fresh marshmallows ensure softer treats. Butter – Binds the ingredients together while adding rich flavor; coconut oil can be used for a dairy-free option.

Step‑by‑Step Instructions for Key Lime Pie Rice Krispie Treats Step 1: Prepare Baking Dish Begin by lining a 9×13-inch pan with parchment paper, allowing some overhang for easy removal later. This will ensure that your Key Lime Pie Rice Krispie Treats can be lifted out smoothly once set. Take a moment to tuck the parchment into the corners of the pan, creating a neat and secure base for your treats. Step 2: Melt Butter and Marshmallows In a large saucepan, melt 4 tablespoons of butter over low heat. Once the butter is fully melted, add in 10 ounces of marshmallows. Stir continuously until the mixture becomes smooth and creamy, which should take about 5-7 minutes. Be sure to keep a close eye to prevent burning, as a nice glossy mixture is key for binding your treats. Step 3: Mix Dry Ingredients Remove the pan from heat and quickly stir in 6 cups of Rice Krispies cereal, 1 cup of graham cracker crumbs, ½ cup of key lime juice, and 1 tablespoon of key lime zest. Mix until every piece is well-coated and the vibrant colors of lime and crispy cereal blend together. You’ll know it’s ready when the mixture holds its shape and has an aromatic, tangy scent. Step 4: Press Mixture Carefully transfer the mixture into your prepared pan, spreading it out evenly. Use a greased spatula or your hands (lightly moistened) to press the mixture firmly down into the corners and sides. Ensure the surface is smooth and even for uniform treats, as this will assist with cutting into perfect squares later on. Step 5: Drizzle Chocolate (Optional) If you’re adding a touch of sweetness, melt about ½ cup of white chocolate in the microwave or over a double boiler until smooth. Once melted, drizzle it over the pressed Rice Krispie mixture, using a spoon or piping bag for a decorative touch. This adds a delightful creamy contrast to the tanginess of your Key Lime Pie Rice Krispie Treats. Step 6: Cool and Set Allow the entire dish to cool at room temperature for about 30 minutes. This will let the treats firm up nicely, making them easier to cut into squares. As the mixture sets, you’ll begin to see the glossy top sheen from the melted chocolate, which enhances the treat’s visual appeal while promising deliciousness in every bite. Make Ahead Options These Key Lime Pie Rice Krispie Treats are perfect for meal prep enthusiasts! You can easily prepare the mixture up to 24 hours in advance. To do this, follow all steps except for cooling and cutting. Simply press the mixture into the lined pan, cover it tightly with plastic wrap, and refrigerate. This prevents the treats from becoming overly sticky while maintaining their delightful texture. When you’re ready to enjoy them, simply remove from the fridge, allow them to come to room temperature for about 15 minutes, and then cut into squares. They’ll be just as delicious, offering a refreshing treat with all the ease you need for busy weeknights! How to Store and Freeze Key Lime Pie Rice Krispie Treats Room Temperature: Store in an airtight container at room temperature for up to 1 week.

Expert Tips for Key Lime Pie Rice Krispie Treats Fresh Ingredients: Use fresh marshmallows for ultimate softness; stale marshmallows can lead to tough treats. Avoid Overpacking: Gently press the mixture into the pan; packing too tightly can make them dense and less enjoyable to eat. Zest Matters: For a bolder citrus flavor in your Key Lime Pie Rice Krispie Treats, don’t skimp on the lime zest; it elevates the taste beautifully. Cool Completely: Ensure your treats are fully cooled before cutting them into squares; warm treats can crumble easily. Cocoa Alternatives: If you prefer a richer taste, try substituting white chocolate with dark chocolate, but remember to melt it carefully to avoid burning.

Chocolate Dip: Serve a side of melted dark chocolate for dipping. It adds a rich, decadent layer to the tangy key lime treats, perfect for those who love a chocolate edge.

How should I store Key Lime Pie Rice Krispie Treats? Store these treats in an airtight container at room temperature for up to 1 week to maintain their chewiness.
