1/2 teaspoon lemon extract (optional for stronger flavor)
For the Frosting:
1/2 cup (1 stick) salted butter, softened
2 cups powdered sugar
2 tablespoons lemon juice
1/2 teaspoon vanilla extract
1–2 tablespoons milk or heavy cream
Yellow food coloring, optional
Sparkly sugar for topping
Instructions
For the Bars:
Preheat oven to 350°F. Line a 9×9-inch baking pan with parchment paper, leaving an overhang for easy removal.
In a large mixing bowl, combine the break-apart sugar cookie dough, chopped Lemon Oreos, lemon juice, and lemon extract (if using). Use a spatula or your hands to mix everything until just combined—don’t overmix.
Press the dough evenly into the prepared pan.
Bake for 20–24 minutes, or until the edges are lightly golden and the center is set. Let the bars cool completely in the pan before frosting.
For the Icing:
In a large bowl, beat the softened butter until smooth and creamy.
Add the powdered sugar, lemon juice, vanilla extract, and milk or cream. Beat until fluffy and spreadable, adding more liquid as needed.
If using, add a drop or two of yellow food coloring for brighter yellow color.
Assembly:
Spread the frosting over the cooled bars in a thick, even layer.
Top with sparkly sugar.
Chill until the bars are cold and have that “frosted” feel and then slice into bars and serve cold.
