Kitchen Equipment You’ll Need

• 9×13-inch baking dish
• Large saucepan
• Mixing bowls
• Silicone spatula
• Stand or hand mixer
• Kitchen torch or oven broiler
• Piping bag (optional, for decorating)

How to Make Lemon Meringue Rice Krispie Treats

Step 1: Prepare Your Pan

Spray a 9×13-inch baking dish with nonstick spray or line it with parchment paper for easy removal.

Step 2: Melt Marshmallows

In a large saucepan, melt the butter over low heat. Add the mini marshmallows and stir continuously until smooth. Sprinkle in the lemon Jell-O powder and lemon extract, stirring until fully incorporated.

Step 3: Add Cereal

Remove the pot from heat and gently fold in the Rice Krispies cereal. Mix until the cereal is evenly coated in the lemon-marshmallow mixture.

Step 4: Press and Set

Transfer the mixture into the prepared baking dish. Press it down evenly using a spatula or lightly greased hands. Let it cool while you make the meringue.

Step 5: Make the Meringue

In a clean, dry bowl, whip the egg whites and cream of tartar until soft peaks form. Gradually add the sugar while beating until glossy, stiff peaks form. Add vanilla extract at the end.

Step 6: Top and Toast

Spread the meringue over the cooled Rice Krispie layer. Use a spatula to create decorative peaks. Toast the meringue with a kitchen torch, or place under the oven broiler for 1–2 minutes, watching closely.

Step 7: Cool and Cut

Allow the treats to cool completely before cutting into squares.

Tips for Perfect Lemonade Rice Krispie Treats

• Use fresh marshmallows for the best texture. Stale marshmallows won’t melt evenly.
• Don’t press too hard when spreading the cereal mixture into the pan. You want soft, airy bars.
• Let everything cool completely before adding meringue. Warm base = melted meringue.
• Use a clean, grease-free bowl for meringue or it won’t whip properly.

Common Mistakes to Avoid

• Skipping the lemon extract: Jell-O adds flavor, but extract gives depth.
• Over-whipping the meringue: It should be stiff and glossy, not dry or crumbly.
• Broiling too long: Just a few seconds can over-toast or burn the meringue.
• Using a hot base for the topping: This melts the meringue and ruins texture.

Fun Variations to Try

Once you’ve mastered the base, try switching up the flavor. Here are some easy ways to adapt this recipe:

• Orange Rice Krispie Treats: Swap lemon Jell-O and extract for orange versions.
• Strawberry Lemonade Version: Use half lemon and half strawberry Jell-O for a fruity twist.
• Mini Lemon Pie Bites: Press into muffin tins and pipe the meringue individually.
• S’mores Style: Add a graham cracker crust to the bottom before pressing in the krispie mix.

Presentation Ideas for Parties and Holidays

Presentation makes a difference, especially for events like Mother’s Day or birthdays.

• Cut the treats into heart or flower shapes using cookie cutters.
• Use a piping bag to swirl meringue like frosting for individual portions.
• Sprinkle with lemon zest or edible glitter for a touch of elegance.
• Serve on a dessert platter with Pumpkin Cinnamon Rolls or Strawberry Cheesecake Cinnamon Rolls for a colorful brunch display.

How to Store Lemon Meringue Rice Krispie Treats

Store the bars in an airtight container at room temperature for up to 2 days. If you must refrigerate, do so for no longer than 3 days, as the meringue may lose its texture.

Avoid freezing the finished product with meringue. However, you can freeze the base and add fresh meringue later.

FAQs About Lemon Rice Krispie Treats

Can I make these without meringue?
Yes! The lemon bars are fantastic on their own or with a dusting of powdered sugar.

What if I don’t have lemon extract?
You can use lemon zest or a splash of lemon juice, though the flavor may be more subtle.

How long will they keep?
They’re best within 1–2 days. If you need longer shelf life, leave off the meringue and store just the base.

Can I use marshmallow fluff instead?
You can, but it won’t hold shape or toast like traditional meringue. Stick with egg whites for the real deal.
