Ingredients
Ingredients
- 2.25 cup all-purpose flour spooned and leveled
- 0.5 tsp baking soda
- 0.5 tsp cream of tartar
- 0.25 tsp salt
- 1 cup unsalted butter softened to room temperature
- 1.5 cup granulated sugar divided (1 cup for dough, 0.5 cup for rolling)
- 1 large egg room temperature
- 1 tbsp key lime zest finely grated (about 4-5 limes)
- 2 tbsp key lime juice freshly squeezed
- 1 tsp pure vanilla extract
- 2 tbsp powdered sugar for optional glaze
Notes
Storage: Keep cookies in an airtight container at room temperature for up to 5 days. Make-Ahead: The dough can be scooped, rolled in sugar, and frozen on a baking sheet. Once solid, transfer to a freezer bag and freeze for up to 3 months. Bake from frozen, adding 1-2 minutes to the bake time. Variations: For a festive touch, whisk 2 tbsp powdered sugar with 1 tsp key lime juice to make a thin glaze and drizzle over cooled cookies. Substitutions: Regular lime zest and juice can be used if key limes are unavailable.
