INGREDIENTS
- Butter — salted butter at room temperature.
- White sugar — for sweetness and structure.
- Egg — 1 large.
- Key limes — both zest and juice for authentic flavor.
- Flour — all-purpose flour, spooned and leveled.
- Baking soda
- Baking powder
- Salt
- White chocolate chips — folded into the dough and a few extra for topping.
STEP BY STEP INSTRUCTIONS
Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
Place the key lime zest and the granulated sugar in a small bowl. Rub the zest into the sugar with your fingers until fragrant to help infuse the sugar with lime aroma.
In a large bowl, cream the room-temperature butter with the lime-infused sugar until light and fluffy, about 4–5 minutes.
Add the egg and key lime juice and mix until fully incorporated.
In a separate bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt.
Add the dry ingredients to the wet mixture and stir until combined, taking care not to overmix.
Fold in the white chocolate chips until evenly distributed throughout the dough.
Scoop portions of dough using about 3 tablespoons per cookie and roll each into a ball. Place them on the prepared baking sheet about 2 inches apart.
Bake for 11–12 minutes, or until the bottoms are just beginning to brown. The centers may appear slightly underbaked — they will finish setting on the hot pan.
While the cookies are still warm, press a few extra white chocolate chips on top and sprinkle with freshly grated key lime zest. Let the cookies cool completely on the baking sheet before transferring.
FREQUENTLY ASKED QUESTIONS
STORING THE COOKIES
Store cooled cookies in an airtight container at room temperature for up to four days.
Can I substitute regular limes?
Regular limes can be used in a pinch, though the flavor will be slightly different. Key limes provide a distinctive aroma and acidity that make these cookies special.
WHAT DOES “SPOONED AND LEVELLED” FLOUR MEAN?
Spoon flour into your measuring cup and level it off with a knife. This prevents packing too much flour into the cup, which can make baked goods dense.
HOW TO GET PERFECTLY ROUND COOKIES
Right after removing cookies from the oven, place a round cookie cutter (slightly larger than the cookie) around each one and gently swirl to smooth edges. A glass or jar lid works as an alternative.
CAN I MAKE THE COOKIES SMALLER?
Yes. Use 1½ tablespoon scoops and bake for about 9 minutes, or until the edges are golden.
HOW TO GET CHEWY COOKIES
Slightly underbake them. Remove when the centers still look soft, let cool on the tray, and they’ll finish cooking from the residual heat and become chewy as they set.
CAN I FREEZE THEM?
Yes. Freeze dough balls or fully baked cookies for up to 2 months. Add a few extra minutes to bake time when baking directly from frozen dough.
