Ingredients

Lemon Cookies

  • 3/4 cup salted butter softened, at room temperature
  • 3/4 cup granulated sugar
  • 1 large whole egg
  • 1 large egg yolk
  • 1 teaspoon pure vanilla extract
  • 1 1/2 tablespoons Karo® Syrup
  • 1 tablespoon fresh lemon zest about 1 lemon
  • 1 tablespoon fresh lemon juice about 1/2 lemon
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 2 1/2 cups all-purpose flour

Lemon Buttercream Frosting

  • 1/2 cup salted butter softened, at room temperature
  • 4 cups powdered sugar
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon fresh lemon zest
  • 1 tablespoon Karo® Syrup
  • 1/4 teaspoon vanilla extract

Instructions

To make lemon cookies

  • Preheat the oven to 350 degrees F and line baking sheets with parchment paper.
  • In a large mixing bowl with an electric mixer or in the bowl of a stand mixer with a paddle attachment, cream the butter and sugar together until combined.
  • Add the egg, egg yolk, vanilla extract, corn syrup, lemon juice and lemon zest.
  • Whisk together the flour, baking powder and baking soda in a medium bowl until combined.
  • Add the flour mixture to the wet mixture and mix until cookie dough has formed. Be sure to scrape the sides of the bowl and be sure not to over-mix.
  • Use a regular ice cream scoop equivalent to 1/4 cup to scoop the dough and place on the prepared baking sheet. Lightly press the dough balls down a bit with the bottom of a glass or your fingers. Bake for 12-14 minutes or until the middles aren't super soft (but they will be soft) and the tops won't turn a golden brown
  • Wait a few minutes and then transfer the baked cookies onto a cooling rack and cool completely.

To make buttercream frosting

  • While the cookies cool, make the lemon buttercream frosting by creaming the butter together until smooth in a medium bowl. Add the corn syrup, lemon juice, lemon zest, and vanilla extract.
  • Add in 1 cup of powdered sugar at a time and 1 tablespoon of milk. Beat together, then add the remaining powdered sugar and milk. Beat for a few minutes until frosting is creamy, smooth and fluffy. Add in more powdered sugar to thicken the frosting or milk to thin it out. 
  • Use a butter knife or offset spatula to frost the cooled cookies and top with more lemon zest and sprinkles (optional) enjoy!
