Step‑by‑Step Instructions for Lemon Meringue Rice Krispie Treats
Step 1: Prepare the Baking Dish
Lightly spray a 9 x 13-inch baking dish with non-stick cooking spray. This ensures your Lemon Meringue Rice Krispie Treats won’t stick when you try to cut them. Make sure to cover all corners for an easy release once everything is set.
Step 2: Make the Lemon Curd
In a double boiler, combine unsalted butter, fresh lemon juice, lemon zest, and sugar. Stir gently over simmering water until fully melted. Gradually whisk in the room-temperature beaten eggs, continuing to stir until the mixture thickens, roughly 10 minutes. Once thickened, remove from heat, cool briefly, and refrigerate until set.
Step 3: Prepare the Rice Krispie Layer
In a large saucepan over low heat, melt butter with marshmallows, stirring until smooth and fully combined. Stir in the instant lemon pudding until well incorporated, then fold in the Rice Krispies cereal. Press this mixture evenly into the prepared baking dish, ensuring it’s packed tightly, and allow it to cool completely at room temperature.
Step 4: Make the Meringue
In a heatproof bowl over simmering water, whisk together large egg whites, granulated sugar, cream of tartar, and sea salt. Continue whisking until the mixture becomes hot to the touch, about 3 minutes. Transfer to a stand mixer and beat on high speed until stiff peaks form, approximately 5 minutes, then fold in vanilla extract.
Step 5: Assemble the Treats
Once the Rice Krispie layer has cooled completely, evenly spread the chilled lemon curd over it. Carefully dollop the prepared meringue on top and spread it out using a spatula, ensuring a beautiful and fluffy layer for your Lemon Meringue Rice Krispie Treats.
Step 6: Brown the Meringue
To achieve that enticing golden top, use a kitchen torch to lightly brown the meringue, moving it evenly across the surface. If you don’t have a torch, place the treats under a broiler for about 1 minute, keeping a close eye to avoid burning. Once done, your treats are ready to impress!

Expert Tips for Lemon Meringue Rice Krispie Treats
-
Grease-Free Utensils: Ensure all tools for whipping meringue are clean and grease-free. Any residual fat can prevent the egg whites from whipping properly.
-
Watch the Heat: When using a double boiler for the lemon curd, keep the heat low to avoid curdling the eggs. Slow and steady is key for that perfect curd consistency.
-
Cool Completely: Allow the Rice Krispie layer to cool completely before adding the lemon curd. This prevents melting or oozing, keeping the layers distinct.
-
Avoid Over-Beating: Once stiff peaks form in the meringue, stop beating! Over-beating can create a grainy texture, so monitor carefully.
-
Flavor Play: Feel free to swap the lemon pudding for a different flavor, but ensure it complements the freshness of the lemon curd for delicious Lemon Meringue Rice Krispie Treats.

Lemon Meringue Rice Krispie Treats Recipe FAQs
What type of lemons should I use for the lemon curd?
Absolutely! Fresh lemons are best for making the lemon curd, as they provide vibrant flavor and richness. When choosing lemons, look for ones that are firm, heavy for their size, and have smooth, shiny skin. Avoid any lemons with dark spots or wrinkles, as they may be past their prime.
How should I store the treats?
Very good question! You can store your Lemon Meringue Rice Krispie Treats in an airtight container in the refrigerator for up to 5 days. Just make sure they are fully cooled before sealing to maintain freshness. If you need to keep them longer, wrap them tightly in plastic wrap and place them in a freezer-safe container for up to 3 months.
Can I freeze the Lemon Meringue Rice Krispie Treats?
You can indeed freeze these delightful treats! To freeze, wrap them tightly in plastic wrap, then place them in a freezer-safe container or bag. When you’re ready to enjoy, transfer the treats to the refrigerator to thaw overnight. If you prefer them slightly warm, simply microwave individual pieces for 10-15 seconds before serving.
What if my meringue doesn’t form stiff peaks?
No worries, this can happen to the best of us! If your meringue isn’t forming stiff peaks, it may be due to the presence of grease on your mixing bowl or utensils, or perhaps the egg whites weren’t at room temperature. Start by ensuring everything is squeaky clean and try again with room temperature egg whites. Beat until the mixture is glossy and the peaks stand tall. If you still face issues, gently fold in an additional egg white to improve the texture.
Can I make these treats gluten-free?
Absolutely, the Lemon Meringue Rice Krispie Treats can easily be made gluten-free! Just ensure that you use gluten-free Rice Krispies, which are widely available. Double-check other ingredient packaging, such as the marshmallows, to make sure they don’t contain any gluten.
