Ingredients Equipment Method Notes

Ingredients
  

flour
  • 2.25 cup flour
butter
  • 1 cup butter softened
sugar
  • 1 cup sugar
egg
  • 1 egg
key limes
  • 3 key limes zest and juice
vanilla extract
  • 1 tsp vanilla extract
baking powder
  • 1 tsp baking powder
powdered sugar
  • 1 cup powdered sugar for glaze

Equipment

  • 1 sheet pan

Method
 

Bake the cookies
  1. Preheat the oven to 350°F and line a sheet pan for easy transfer. Arrange the pan so cookies can bake evenly without overcrowding.
  2. Cream butter and sugar together until fluffy. Mix until the color lightens and the texture looks aerated.
  3. Beat in the egg, vanilla extract, lime zest, and 2 tbsp lime juice. Keep mixing until the batter is smooth and glossy.
  4. Fold in the flour and baking powder until just combined. Stop mixing as soon as no dry streaks remain to keep the cookies tender.
  5. Scoop dough onto the prepared sheet pan, spacing them apart. Bake for 10-12 minutes at 350°F until the edges are just golden.
Make and add the lime glaze
  1. Whisk powdered sugar with the remaining lime juice until smooth. The glaze should be pourable and thick enough to coat.
  2. Drizzle the glaze over cooled cookies. Let the glaze set before stacking or serving.

Notes

Pro tip: zest the key limes before juicing them—zesting is much easier when the fruit is firm. Store cookies in an airtight container at room temperature for up to 3 days or in the fridge for up to 5 days; freeze baked cookies for up to 2 months (glaze after thawing for best texture). For a dairy-free swap, use a 1:1 dairy-free butter alternative and proceed as directed.
