Lemon Shortbread Cookies Recipe - Lemon Shortbread Cookies make a delicious slice and bake cookie recipe perfect for sharing! Made with fresh lemons, this cookie recipe has just the perfect amount of sweet and tart that lemon lovers adore!
Cream together the butter, cornstarch, and confectioner's sugar with an electric mixer until well-combined, about 3 minutes. Add flour to the butter mixture until just combined. Add the lemon zest and the lemon juice. Beat until thoroughly mixed and a soft dough is formed.
Divide the dough in half and turn each half out onto a piece of parchment or waxed paper. Form each half into a 1-inch roll, twisting the ends of the paper to seal. Refrigerate until firm, about 1 hour.
When ready to bake, preheat the oven to 350ºF. Slice the dough into 1/4-inch slices and place onto a rimmed baking sheet lined with parchment paper. Bake until set, about 10 minutes. Cookies will not brown. Remove from the oven and allow to cool.
For the Lemon Glaze
Add the confectioner's sugar to a medium mixing bowl. Stir in the lemon zest and lemon juice, stirring until the glaze is smooth.
Once the lemon shortbread cookies have cooled completely, spoon about 1/2 teaspoon of glaze onto each cookie and spread around the center of the cookie. Allow the glaze to set and serve.
