Ingredients

• Zest of 2 lemons (around 2-4 tbsp), divided
• Juice of 1 lemon (you'll want around 1½ tbsp - 2 of juice)
• 1 cup (110 g) powdered sugar
• 13 gluten-free Golden Oreos -- other cookies that would work well are Glutino Vanilla Creme or Lemon Sandwich Cookies, or any gluten-free butter cookie or shortbread cookie
• 1 stick (½ cup) salted butter
• 10.5 oz bag gluten-free mini marshmallows
• ¾ tsp kosher salt
• ½ tsp vanilla extract
• 6 cups (about 200 g) gluten-free fruity cereal (like Three Wishes Fruity Grain Free Cereal, or your favorite. Honey-flavored cereal would also work with this recipe!)

Instructions

Prep Before You Start

1. Line a 9x13-inch baking dish with parchment paper. Lightly grease with cooking spray or rub with the butter wrapper.
2. Roughly break up 13 cookies into chunky pieces — it should be about 1 cup. You want noticeable chunks, not crumbs.
3. Zest both lemons and set zest aside (you’ll use half in the glaze and half in the cereal treats).
4. Juice one lemon and measure out 1½ to 2 tablespoons of juice. Set aside. (Save the second lemon for another use.)

Make the Lemon Glaze

1. In a medium bowl, combine all the powdered sugar, and half the lemon zest.
2. Slowly whisk in the lemon juice 1 teaspoon at a time, stirring well between additions, until you have a thick glaze. The goal is a glaze that’s the texture of school glue: thick enough to sit on top of the bars without soaking in.
3. If your lemon was small and flavor is lacking, add a few drops of lemon extract to boost the zing (optional).
4. Set glaze aside.

Make the Cereal Treats

1. In a large pot, melt 1 stick of salted butter over medium heat.
2. Add the entire bag of marshmallows and stir continuously until completely melted and smooth.
3. Remove from heat. Immediately stir in the kosher salt, vanilla extract, and the remaining lemon zest.
4. Quickly fold in the gluten-free fruity cereal and almost all of the cookie chunks.
5. Stir until everything is evenly coated in the marshmallow mixture.
6. Scrape the mixture into your prepared baking dish. Use greased hands, a greased square of parchment paper, or a greased spatula to press it evenly into the pan.
7. If you saved some cookie chunks, scatter these over the top and then press them into the mixture.

Finish & Set

1. Drizzle or spread the lemon glaze evenly over the top of the treats while they’re still slightly warm, but no longer hot.
2. Let cool completely at room temperature or in the fridge (about 1 hour).
3. Slice into 20 bars

Notes

Storage Tip:

Keep treats in an airtight container at room temperature for up to 3 days. For extra lemony punch, drizzle a bit more glaze just before serving.
