Key Lime Cookies
Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper.
- In a mixing bowl, cream together the softened butter and granulated sugar using a hand or stand mixer until the mixture is light, fluffy, and pale in color—about 2-3 minutes. You should hear a gentle whirling and see the color brighten.
- Add the lime zest and vanilla extract to the butter mixture and mix until evenly incorporated, releasing fragrant citrus aromas.
- Gradually add the flour to the wet ingredients, mixing on low speed until just combined and the dough begins to come together.
- Pour some coarse sugar onto a small plate. Scoop roughly one tablespoon of dough and roll it into a ball, then press it slightly to form a thick disc.
- Roll each dough piece in the coarse sugar until fully coated, creating a sparkly, textured surface.
- Place the coated dough balls onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading.
- Bake in the preheated oven for 8-10 minutes, or until the edges are just golden and the centers look set but still soft.
- Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely and set their texture.
- Once cooled, enjoy these fragrant, tangy cookies with their crisp exterior and tender interior, perfect for a bright citrus treat.
Every bite of these Key Lime Cookies feels like a tiny celebration of summer’s glow. They’re a reminder that the simplest ingredients—lime, butter, sugar—can come together to create something special. Sharing them is a quiet joy, a way to keep a little sunshine close.
