- 1/4 teaspoon salt

Step-by-Step Instructions
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
- Add Egg and Lime: Beat in the egg, key lime juice, and key lime zest until well combined.
- Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.

What to Serve Key Lime Cookies With

For a festive touch, serve them alongside fresh fruit salad or a scoop of vanilla ice cream to balance the tanginess. You can also enjoy them with a light, fluffy whipped cream to complement the flavors perfectly!
Top Tips for Perfecting Key Lime Cookies
- Use Fresh Key Limes: For the best flavor, opt for fresh key limes instead of bottled juice. If you can’t find key limes, regular limes will work too!
- Check Your Baking Soda: Make sure your baking soda is fresh to ensure a good rise.
- Adjust for Humidity: If you live in a humid area, you may need to slightly increase the flour to avoid a sticky dough.
- Chill the Dough: For slightly thicker cookies, consider chilling the dough for about 30 minutes before baking.
Storing and Reheating Tips
Store leftover Key Lime Cookies in an airtight container at room temperature for up to one week. For longer storage, you can freeze them for up to three months. When you’re ready to enjoy them again, just thaw at room temperature or pop them in the microwave for a few seconds to warm them right up!
