Ingredients

  • 1 lemon, zested and juiced, see notes
  • 1 Tablespoon granulated sugar
  • ½ cup powdered sugar
  • 6 Tablespoons salted butter
  • 16 ounce bag mini marshmallows, divided
  • ½ teaspoon lemon extract
  • ½ teaspoon vanilla extract
  • 6 cups Rice Krispies cereal

Instructions

    Cup of Yum
  1. Start by making the lemon topping. Zest one lemon in a small bowl. Add 1 Tablespoon of granulated sugar and mix with a spoon until crumbly and combined. Set aside.
  2. Juice the same lemon in a small bowl. Add in powdered sugar and whisk until smooth. Set aside.
  3. Line a 9-inch square baking dish with parchment paper. Set aside.
  4. In a large saucepan, melt butter over medium heat. Once melted, add in all but 1 cup of the mini marshmallows, reducing heat to low. Stir with a spatula until marshmallows are completely melted. Remove from heat.
  5. Add in lemon and vanilla extracts, stir until blended. Add cereal and remaining one cup of mini marshmallows, stirring gently until combined.
  6. Pour mixture in prepared baking dish, pressing gently with your fingertips until spread out. Immediately drizzle with the lemon glaze, then add the lemon sugar mixture.
  7. Allow krispie treats to set for about one hour. Cut and enjoy.

Notes

  • For the whole lemon, zest the lemon using our guide on how to zest a lemon. You'll get about 1 teaspoon of zest. For the lemon juice, you'll get about 1 Tablespoon juice.
  • Be sure to use fresh marshmallows and fresh cereal. Using stale ingredients will result in stale treats.
  • Adding the lemon glaze while the krispie treats are warm allows the fresh citrus flavor to sink into the krispie treats. If you prefer a more "finished" look, you can wait to add the toppings. Slice into bars then top each one with glaze and sugar after they have cooled and set.
  • Store lemon krispie treats in airtight container at room temperature for several days.
  • You can also freeze krispie treats by sliding into a ziploc bag. Freeze for up to 3 months.
