These lemon Rice Krispy treats are light, refreshing, and dangerously snackable. One bite in, and you’ll understand why they disappear so fast.
To enhance the lemon flavor, I added freshly grated lemon zest and just a small splash of lemon extract. The result is a delicate citrus note that doesn’t overpower the marshmallow sweetness—just enough to keep you coming back for another bite.
Once the cereal and marshmallows are combined, the mixture is pressed into a pan and left to cool. No oven, no fuss. But the magic doesn’t stop there.
The bars are finished with a delicate white chocolate drizzle and a sprinkle of fresh lemon zest or lemon peel curls. The white chocolate adds a touch of richness that perfectly balances the bright citrus flavor, while the lemon garnish gives these treats a beautiful, bakery-style finish.
Ingredients
- 6 cups Rice Krispies cereal
- 3 tablespoons unsalted butter
- 3 cups mini marshmallows (half lemon-flavored, half classic white)
- Zest of 1 lemon (plus more for garnish, if desired)
- ½ teaspoon lemon extract (optional, but adds extra citrus flavor)
- ½ cup white chocolate chips or melting wafers
- Lemon peel or zest, for garnish
Instructions
1. Prep the Pan
Grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
2. Melt the Marshmallows
In a large saucepan, melt the butter over low heat. Add the mini marshmallows and stir until completely melted and smooth. Stir in the lemon zest and lemon extract, if using.
3. Mix with Cereal
Remove from heat and immediately stir in the Rice Krispies cereal until evenly coated.
4. Press into Pan
Press the mixture gently and evenly into the prepared pan using a buttered spatula or wax paper. Be careful not to press too firmly—this keeps the treats soft and chewy.
5. Drizzle & Decorate
Melt the white chocolate chips in the microwave in 20-second intervals, stirring until smooth. Drizzle over the bars and finish with lemon zest or fine curls of lemon peel.
6. Set & Slice
Let the treats set at room temperature until firm. Slice into bars and enjoy!
