How to Make Key Lime Cookies
Preheat Your Oven: Start by preheating your oven to 350°F (175°C). This ensures your cookies bake evenly and rise properly while delivering that freshly baked aroma straight into your home.
Mix Dry Ingredients: In a medium bowl, whisk together flour, baking powder, and salt until well combined. This step helps distribute the leavening agent evenly throughout the flour.
Cream Butter and Sugar: In a large bowl, beat together unsalted butter and granulated sugar using an electric mixer until creamy and smooth—about 3-4 minutes should do it! The mixture should look pale and fluffy.
Add Egg and Lime Juice/Zest: Beat in one egg along with fresh Key lime juice and zest until well incorporated. You’ll want to do this until everything looks well combined—a little lime zest will make you feel like summer!
Combine Wet and Dry Mixtures: Gradually add your dry ingredients into the wet mixture while mixing on low speed until just combined. Be careful not to overmix because nobody likes tough cookies!
Scoop Dough onto Baking Sheet: Using a cookie scoop or spoon, drop rounded tablespoons of dough onto an ungreased baking sheet, spacing them about 2 inches apart. Give them room to spread while baking—no one wants cookies stuck together!
Once you’ve followed these steps, pop those bad boys into your preheated oven and let them bake for about 10-12 minutes until they’re lightly golden around the edges. Allow them to cool slightly before dusting with powdered sugar for that extra touch of elegance.
Now you’re ready to savor each tangy bite of these delightful Key Lime Cookies! Enjoy them at beach picnics or during cozy evenings at home—they’re perfect for any occasion!
