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 recommended for 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 easy removal of the treats once set.
  2. Melt Butter and Marshmallows: In a large saucepan over low heat, melt the unsalted butter. Once melted, add the mini marshmallows and stir continuously until completely melted and the mixture is smooth.
  3. Add Lemon Flavor: Stir in the lemon zest and lemon extract (if using) into the melted marshmallow mixture to incorporate the citrus flavor evenly.
  4. Combine with Cereal: Remove the pan from heat and quickly fold in the Rice Krispies cereal, stirring until all cereal pieces are well coated with the marshmallow mixture.
  5. Press Mixture into Pan: Using a buttered spatula or wax paper, gently press the mixture evenly into the prepared baking pan. Avoid pressing too hard to keep the treats soft and chewy.
  6. Melt White Chocolate: In a microwave-safe bowl, melt the white chocolate chips in 20-second intervals, stirring between each until smooth and fully melted.
  7. Drizzle and Garnish: Drizzle the melted white chocolate evenly over the top of the pressed cereal bars. Sprinkle additional lemon zest or fine curls of lemon peel on top for garnish.
  8. Set and Serve: Allow the treats to cool and set at room temperature for at least 30 minutes. Once firm, cut into squares and enjoy.

Notes

  • For a stronger lemon flavor, add an extra 1/4 teaspoon of lemon extract or increase lemon zest slightly.
  • If you prefer a dairy-free version, substitute butter with coconut oil and use dairy-free white chocolate chips.
  • Store leftovers in an airtight container at room temperature for up to 3 days for best texture.
  • Pressing the mixture too hard can make the treats dense; gentle pressure keeps them chewy.
  • These treats do not require refrigeration but can be chilled slightly for a firmer bite.
