- Bake for 10-12 minutes or until the edges are lightly golden.
- Allow the cookies to cool completely on the baking sheet.
- For the glaze, mix the powdered sugar with key lime juice and zest until smooth and silky.
- Drizzle the glaze over the cooled cookies and let it set before serving, making them look simply irresistible!
Fun Ways to Customize It
If you’re feeling adventurous, consider these delicious variations:

Chef Emma’s Helpful Tips
- Make-Ahead: These cookies can be prepared ahead of time and frozen before baking. Just thaw and bake when you’re ready!
- Ingredient Swaps: If you can’t find key limes, regular limes can work in a pinch. They’ll produce a slightly different but still delicious flavor.
- Storage Suggestions: Store in an airtight container at room temperature for up to a week. They also freeze beautifully!
- Glazing Trick: To achieve a thicker glaze, add more powdered sugar, or for a thinner glaze, add more juice.
