Ingredients
  

Wet Ingredients

  • 1 cup unsalted sweet cream butter, softened adds richness and moisture
  • 1.5 cups powdered sugar contributes sweetness and smooth texture
  • 1 large egg binds ingredients together
  • 1 teaspoon fresh lime juice adds acidity and flavor
  • 4 teaspoons lime zest provides fragrant, citrus flavor

Dry Ingredients

  • 2.5 cups all-purpose flour gives structure
  • 1 teaspoon baking soda helps cookies rise
  • 1 teaspoon cream of tartar stabilizes and adds chewiness
  • 1.5 cups granulated sugar sweetens and enhances texture

Instructions
 

Preparation

  • Cream the softened butter and powdered sugar together in a mixing bowl until light and fluffy.
  • Add the egg, fresh lime juice, and lime zest to the mixture, and mix until just combined.
  • In a separate bowl, whisk together the all-purpose flour, baking soda, and cream of tartar.
  • Gradually add the dry ingredient mixture to the wet mixture, stirring gently with a spatula until just combined.
  • Incorporate the granulated sugar and additional lime zest into the dough, mixing until evenly distributed.

Baking

  • Preheat your oven.
  • Scoop out portions of dough and roll them into balls, placing them evenly spaced on a baking sheet.
  • Gently flatten each ball to create a disc about half an inch thick.
  • Bake cookies in the preheated oven for about 10 to 12 minutes or until edges are light golden.
  • Let cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.

Notes

Store cookies at room temperature in an airtight container for up to a week. For longer storage, refrigerate or freeze them.
