How to make Lemon Meringue Rice Krispie Treats

Making Lemon Meringue Rice Krispie Treats is a classic way to combine two beloved treats into one delectable dessert. This recipe is easy to follow and perfect for any occasion. It features crispy cereal, sweet marshmallows, and zesty lemon, making for a delightful treat that will have everyone asking for seconds.

Ingredients:

6 tablespoons fresh lemon juice (use store-bought if short on time)
4 large eggs (for richness)
8 tablespoons unsalted butter (can substitute with vegan butter)
6 tablespoons fresh lemon juice (bottled is acceptable)
2 large freshly grated lemons (for zest)
1 cup sugar (can use coconut sugar)
4 tablespoons unsalted butter (substitute with coconut oil for dairy-free)
10 ounces marshmallows (mini marshmallows can work too)
3.4 ounces instant lemon pudding (can swap for vanilla pudding)
6 cups Rice Krispies cereal (gluten-free varieties available)
2 large egg whites (room temperature)
½ cup granulated sugar (use sugar substitute if needed)
⅛ teaspoon cream of tartar (omitting may affect texture)
A pinch fine sea salt (can use kosher salt)
½ teaspoon pure vanilla extract (optional)

Directions:

Prepare Ingredients: Gather all your ingredients and measure them out. This will make the process smoother and quicker.
Make the Lemon Mixture: In a medium saucepan over low heat, melt the butter and add 6 tablespoons of fresh lemon juice, sugar, and lemon zest. Stir until fully combined.
Add Marshmallows: Add the marshmallows to the saucepan and continue stirring until they are completely melted and smooth.
Stir in Rice Krispies: Remove the mixture from heat and fold in the Rice Krispies cereal until thoroughly coated.
Transfer to a Baking Dish: Quickly transfer the mixture into a greased 9×13-inch baking dish. Use a spatula to press it down evenly. Make sure to press it firmly but gently to maintain its texture. Set aside to cool slightly.
Make the Meringue: In a clean mixing bowl, beat the egg whites with a hand mixer on medium speed. Slowly add the granulated sugar and cream of tartar while beating until stiff peaks form (about 3-5 minutes).
Spread Meringue: Once the lemon Rice Krispie layer is slightly set, spread the meringue over the top. Create peaks for an attractive look.
Bake: Preheat your oven to 350°F (175°C) and bake for about 10-12 minutes or until the meringue is golden brown. Keep an eye on it to avoid over-baking.
Cool and Slice: Let the treat cool completely before slicing into squares or rectangles.

How to Store Lemon Meringue Rice Krispie Treats

To keep your treats fresh, store them in an airtight container at room temperature. They should last for about 3 to 5 days. For longer storage, you can freeze them cut into pieces and wrapped separately in plastic wrap, then placed in a freezer-safe container. Thaw them by letting them sit at room temperature before enjoying.

Tips and Mistakes to Avoid

Don’t Overmix: When combining the marshmallows and Rice Krispies, be gentle. Overmixing can lead to a tough texture.
Use Fresh Ingredients: Fresh lemons will give the best flavor. Bottled lemon juice is convenient but may lack the punch of fresh.
Keep Meringue in Check: Make sure your mixing bowl is free of grease to ensure the egg whites whip properly.
Watch the Meringue: The meringue can burn quickly, so keep an eye on it while baking.

Variations (if any)

Add Coconut: For a tropical twist, add shredded coconut to the Rice Krispies mixture.
Use Different Puddings: Swap lemon pudding for a different flavor such as vanilla or white chocolate for a unique taste.
Garnish with Candies: Top with crushed candies or sprinkles to add a fun look.
