Ingredients You’ll Need
Getting the perfect Lemon Meringue Rice Krispie Treats starts with a handful of straightforward ingredients that each play a starring role. From tangy lemon curd to the crispy crunch provided by Rice Krispies cereal, every component contributes to the flavor, texture, and irresistible appeal of this dish.
- Eggs (4 large, plus 2 large whites): Essential for both the silky lemon curd and the light, airy meringue topping.
- Unsalted butter (8 tablespoons for curd, 4 tablespoons for cereal layer): Adds richness and helps create that melt-in-your-mouth texture.
- Fresh lemon juice (6 tablespoons): Provides the bright citrus punch that makes these treats uniquely lemony.
- Lemon zest (freshly grated from 2 large lemons): Intensifies the lemon aroma and adds bursts of flavor.
- Sugar (1 cup for curd, ½ cup for meringue): Balances the tartness of lemon for perfect sweetness in both layers.
- Marshmallows (1 10-ounce package): Melts down to give the Rice Krispie layer its signature chewy, gooey texture.
- Instant lemon pudding mix (1 3.4-ounce package): Enhances both the lemon flavor and creaminess of the cereal layer.
- Rice Krispies cereal (6 cups): The crispy backbone of this treat that keeps every bite fun and crunchy.
- Cream of tartar (⅛ teaspoon): Stabilizes the meringue, helping it reach perfect fluffy peaks.
- Fine sea salt (a pinch): Enhances all the flavors and balances the sweetness.
- Pure vanilla extract (½ teaspoon): Brings warmth and depth to the meringue topping.
How to Make Lemon Meringue Rice Krispie Treats
Step 1: Prepare the Lemon Curd
Start by beating the four large eggs in a small bowl to get them ready for the curd. Next, in a medium heatproof bowl set over simmering water (like a double boiler), combine butter, fresh lemon juice, lemon zest, and sugar. Stir continuously until the butter melts and the sugar dissolves to a silky smooth blend. To gently bring the eggs up to temperature without scrambling, slowly whisk a bit of the warm lemon mixture into the beaten eggs before gradually incorporating the eggs back into the warm mixture. Cook this over the simmering water while stirring constantly until the curd thickens—this can take up to 20 minutes, so patience is key. Once thick and luscious, transfer the curd to a bowl, cover it with plastic wrap pressed against the surface to avoid skin forming, and chill until cold.
Step 2: Make the Rice Krispies Layer
While your curd chills, get ready to make the crunchy Rice Krispie layer. Melt 4 tablespoons of unsalted butter in a large pot over medium heat. Then add the marshmallows and stir until they’re completely melted and smooth. Quickly whisk in the instant lemon pudding mix to infuse more lemon flavor and some extra creaminess. Once combined, remove the pot from heat and fold in the Rice Krispies cereal, making sure every bit is coated in the sticky mixture. Press this mixture gently into your prepared 9 x 13-inch baking dish, creating an even layer. This forms the perfect base for your Lemon Meringue Rice Krispie Treats.
Step 3: Spread the Lemon Curd
Now that your Rice Krispies base is ready, spoon the chilled lemon curd evenly over the top. This tangy layer adds a luscious contrast to the crispy base, making these treats delightfully balanced and bursting with bright flavors.
Step 4: Prepare the Meringue Topping
In a clean, dry bowl, beat the two egg whites at room temperature with cream of tartar and a pinch of fine sea salt until foamy. Gradually add granulated sugar while continuing to beat until stiff, glossy peaks form. Finally, fold in the vanilla extract for a subtle, warming note. Spread this fluffy meringue generously over the lemon curd layer.
Step 5: Bake the Meringue
Pop the assembled dish into a preheated oven at 350°F (175°C) and bake until the meringue is beautifully golden on top, typically about 8 to 10 minutes. Keep an eye on it; that golden glow is what transforms these Lemon Meringue Rice Krispie Treats into tiny works of art. Once done, allow the dish to cool completely before slicing and serving.
How to Serve Lemon Meringue Rice Krispie Treats

Garnishes
To really bring these treats to the next level, sprinkle some extra freshly grated lemon zest over the top right after baking, adding zesty aroma that’ll wake up your senses. A few delicate mint leaves make for a charming, colorful contrast that’s almost too pretty to eat. If you’re feeling indulgent, a light dusting of powdered sugar adds a pretty snow-like finish.
Side Dishes
These Lemon Meringue Rice Krispie Treats shine on their own, but pairing them with a crisp glass of iced tea or a refreshing lemonade makes for a flawless combination at picnics or summer gatherings. For a more indulgent twist, serve alongside vanilla bean ice cream to contrast the citrus brightness with creamy sweetness.
Creative Ways to Present
Stack them as petit fours on a dessert tray for a party, or cut them into fun shapes using cookie cutters for kids’ lunches or themed events. You can also layer them in clear jars to show off the crispy, curd, and meringue layers — it’s a feast for the eyes and the palate. Wrapping individual squares in parchment paper tied with twine creates a charming homemade gift that friends and family will adore.
Make Ahead and Storage
Storing Leftovers
These treats keep beautifully when stored in an airtight container at room temperature for up to 3 days. The meringue topping might lose a bit of its crispness over time but will still taste fantastic. Avoid refrigerating if you want to maintain that signature crispy texture, as moisture can make the cereal layer less crunchy.
Freezing
If you want to save them for later, feel free to freeze the Lemon Meringue Rice Krispie Treats. Wrap individual pieces tightly in plastic wrap and place them in a freezer-safe container. They’ll keep well for up to a month. When ready to enjoy, thaw them at room temperature; however, note that meringue texture might soften slightly after freezing.
Reheating
Since these treats are best enjoyed fresh, reheating isn’t typically necessary. However, if the meringue looks a bit flat after storage, you can pop the treats in a warm oven at 300°F for a few minutes to revive a touch of that golden top. Just watch closely to prevent overbrowning.
FAQs
Can I use store-bought lemon curd instead of making it from scratch?
Absolutely! While homemade lemon curd offers a fresh, vibrant flavor that really elevates these treats, high-quality store-bought curd can be a convenient substitute that still tastes delicious.
Is it safe to eat the meringue made with raw egg whites?
Using pasteurized egg whites is the safest way to enjoy this meringue. Alternatively, you can use a Swiss or Italian meringue method where the egg whites are gently heated with sugar to eliminate any risk.
Can I substitute another cereal for Rice Krispies?
You can experiment with other cereals, but keep in mind they may alter both texture and taste. Rice Krispies provide that classic light crunch which balances the creamy lemon curd beautifully.
How do I know when the lemon curd is thick enough?
The curd is ready when it coats the back of a spoon and leaves a clear line when you run your finger through it. It should have a velvety texture and hold shape without being too runny.
Can I prepare the components separately in advance?
Yes! You can make the lemon curd and meringue ahead of time. Simply store the curd in the refrigerator and prepare the meringue just before assembling and baking to achieve the best texture.

- ⅛ teaspoon cream of tartar
- A pinch of fine sea salt
- ½ teaspoon pure vanilla extract
Instructions
- Prepare Baking Dish: Spray a 9 x 13-inch baking dish with cooking spray to prevent sticking and set aside.
- Make Lemon Curd: In a small bowl, beat the 4 large eggs until blended. In a medium heatproof bowl set over simmering water (double boiler), combine 8 tablespoons unsalted butter, 6 tablespoons fresh lemon juice, zest of 2 lemons, and 1 cup sugar. Stir continuously over simmering water until butter is melted and sugar dissolves, creating a smooth mixture. Slowly and continuously whisk by ladling some of the hot sugar mixture into the beaten eggs to temper them. Gradually pour the egg mixture back into the hot sugar mixture, whisking constantly. Continue to cook and stir gently for up to 20 minutes, or until the curd thickens to a custard-like consistency. Remove from heat, cover surface with plastic wrap to prevent skin, and refrigerate until cold.
- Make Rice Krispies Layer: In a large pot, melt 4 tablespoons unsalted butter over low heat. Add 10 ounces marshmallows and stir until completely melted and smooth. Remove from heat and quickly stir in the instant lemon pudding mix until combined. Fold in 6 cups Rice Krispies cereal evenly. Spread this mixture into the prepared baking dish in an even layer and let cool slightly.
- Prepare Meringue: Preheat oven to 350°F (175°C). In a clean mixing bowl, beat 2 large egg whites with ⅛ teaspoon cream of tartar and a pinch of fine sea salt until soft peaks form. Gradually add ½ cup granulated sugar, continuing to beat until stiff glossy peaks form. Beat in ½ teaspoon pure vanilla extract last.
- Assemble and Bake: Spread the chilled lemon curd evenly over the Rice Krispies layer in the baking dish. Then carefully spread or pipe the meringue over the lemon curd layer. Bake in the preheated oven for about 10-12 minutes until the meringue is set and golden brown on top.
- Cool and Serve: Remove from oven and allow to cool completely on a wire rack before slicing into squares. Refrigerate for best texture before serving if desired.
Notes
- Make sure to temper the eggs slowly when adding the hot lemon mixture to prevent curdling.
- Use fresh lemon juice and zest for the best flavor in the lemon curd.
- Room temperature egg whites whip better for meringue volume and stability.
- Store leftovers covered in the refrigerator for up to 3 days.
- For a dairy-free version, substitute butter with a vegan margarine and use dairy-free marshmallows.
