Ingredients
Here’s everything you need to make a batch of soft and chewy Lemon Rice Krispy Treats:
- 4 tablespoons unsalted butter
- 1 package (about 300 g) mini marshmallows
- 6 cups crispy rice cereal
- 1 teaspoon lemon extract
- 1 tablespoon fresh lemon zest
- ½ teaspoon vanilla extract (optional but recommended)
- ½ cup white chocolate chips (optional for drizzle)
- Pinch of salt
Step-by-Step Instructions
Step 1 – Prepare the Pan
Line a square baking dish with parchment paper or lightly grease it with butter. This prevents sticking and helps you remove the bars easily once they set.
Step 2 – Melt the Butter and Marshmallows
In a large saucepan over low heat, melt the butter gently. Add the mini marshmallows and stir continuously until completely melted and smooth. Keep the heat low to maintain a soft texture.
Step 3 – Add Lemon Flavor
Remove the pan from heat and stir in the lemon extract, fresh lemon zest, vanilla extract, and a pinch of salt. Mix well so the citrus aroma spreads evenly through the marshmallow mixture.
Step 4 – Combine with Rice Cereal
Add the crispy rice cereal gradually and fold it into the melted marshmallow mixture using a spatula. Make sure every piece is evenly coated but avoid pressing too hard to keep the treats light and chewy.
Step 5 – Shape the Treats
Transfer the mixture into the prepared pan. Lightly press it down using a buttered spatula or parchment paper. Do not compress too firmly, as this can make the bars dense.
Step 6 – Add Optional Topping
If you like extra sweetness, melt the white chocolate chips and drizzle them over the top. You can also sprinkle a little extra lemon zest for decoration.
Step 7 – Cool and Slice
Allow the mixture to cool at room temperature for about 30–45 minutes. Once firm, lift the slab out of the pan and cut into squares or rectangles

Tips for Perfect Lemon Rice Krispy Treats
- Use fresh lemon zest for the best flavor and natural aroma.
- Melt marshmallows slowly to keep the texture soft.
- Lightly grease your hands or spatula to prevent sticking while shaping.
- For cleaner cuts, chill the bars in the refrigerator for 10 minutes before slicing.
Flavor Variations
If you want to customize this recipe, try these ideas:
- Add shredded coconut for a tropical touch.

- Use lemon-flavored marshmallows for a brighter color.
- Sprinkle crushed cookies on top for extra crunch.
How to Store Lemon Rice Krispy Treats
Store the bars in an airtight container at room temperature for up to three days. Avoid refrigeration for long periods, as it can make them firm. If stacking the treats, place parchment paper between layers to prevent sticking.
