Ingredients

Scale

Main Ingredients

  • 6 cups Rice Krispies cereal
  • 3 tablespoons unsalted butter
  • 3 cups mini marshmallows (half yellow lemon-flavored, half classic white)
  • Zest of 1 lemon (plus more for garnish if desired)
  • 1/2 teaspoon lemon extract (optional but adds a citrus boost)

Topping

  • 1/2 cup white chocolate chips or melting wafers
  • Lemon peel or zest, for garnish

Instructions

  1. Prepare the Pan: Grease a 9×9-inch baking pan or line it with parchment paper to ensure the Rice Krispy treats can be easily removed once set.
  2. Melt Butter and Marshmallows: In a large saucepan over low heat, melt the unsalted butter slowly. Add the mini marshmallows and stir continuously until they are completely melted and form a smooth mixture.
  3. Add Lemon Flavor: Stir in the zest of one lemon and, if using, the 1/2 teaspoon of lemon extract to infuse the marshmallow mixture with bright, citrusy flavor.
  4. Combine with Cereal: Remove the saucepan from heat immediately and fold in the Rice Krispies cereal until every piece is thoroughly coated with the lemony marshmallow mixture.
  5. Press into Pan: Using a buttered spatula or wax paper, press the mixture evenly into the prepared pan. Avoid pressing too hard to maintain a soft and chewy texture in the treats.
  6. Melt White Chocolate: Microwave the white chocolate chips in 20-second intervals, stirring occasionally until completely melted and smooth.
  7. Drizzle and Garnish: Drizzle the melted white chocolate over the Rice Krispy mixture, then sprinkle additional lemon zest or fine lemon peel curls on top for garnish and extra visual appeal.
  8. Cool and Set: Allow the treats to cool at room temperature for at least 30 minutes so they can firm up. Once set, cut into squares and serve.

Notes

  • Using half lemon-flavored marshmallows adds a natural citrus brightness, but you can use all classic marshmallows and increase lemon zest and extract if preferred.
  • For easy removal, lining the pan with parchment paper is highly recommended.
  • Do not over-press the mixture into the pan to keep the treats soft and chewy rather than hard and dense.
  • The lemon extract is optional but recommended to intensify the lemon flavor without adding liquid.
  • Store leftovers in an airtight container at room temperature for up to 3 days to maintain freshness and texture.
