White Chocolate Key Lime Cookies

Summer is almost here, and for me, that means something VERY important – it’s time to bring out all the key lime desserts! Everything about the flavor of key lime makes me want to chill by the beach with a piña colada.

As much as I love Frozen Key Lime Pie and Key Lime Pie Frozen Yogurt, these white chocolate chip cookies have really won my heart lately… They might be my new key lime favorite. Well, for this summer, at least!

Between the sweetness of the white chocolate chips, the tangy lime zest and the perfectly baked cookie dough, these cookies are all around perfection. They come together in just under 30 minutes, making them an easy to make dessert to whip up before your next pool party!

Variations to Try

  • Like I mentioned before, the lime zest can be swapped! Sometimes, I make these cookies with orange zest and they remind me of creamsicles. You could do the same thing with lemon, too!
  • Toss in some added macadamia nuts for a satisfying crunch.
  • If you can get your hands on some, try tossing a teaspoon of lime extract to the cookie dough. It’s a delicious way to really elevate the overall lime flavor!

How to Make White Chocolate Key Lime Cookies

Prepare. Start off by preheating your oven to 350°F. While that’s heating up, line two baking sheets with parchment paper or silicone baking mats, and set aside.

Mix. In a stand mixer, beat the butter and sugars until light and fluffy. Then, add the egg and vanilla extract to the mix.

Dough has been mixed in a large white mixing bowl.
A large spoon has been placed in the bowl of cookie dough.

Combine. Mix together the wet and dry ingredients, mixing together to thoroughly combine. Once you have a cookie dough formed, stir in the lime zest and white chocolate chips until evenly distributed.

Twelve balls of cookie dough are spread out over a baking sheet.

Roll. Roll two heaping tablespoons of dough into a ball. Tear the ball in half and place the torn side down on the cookie sheet. Take the second half and place it on top of the first half, leaving about two inches for spreading.

Bake. Bake the cookies for about 10 minutes, or until the edges are very slightly browned. The cookies will not look cooked entirely in the center, which is fine! They will finish cooking while cooling on the cookie sheet.

Cookies are cooling on a wire cooling rack.

Cool. Remove the cookies from the oven and allow them to rest on the baking sheet for at least 5 minutes before transferring to a wire rack to completely cool. This is important, as you don’t want the cookies falling apart as you move them!

Also, a pro tip – Try not to burn your mouth on that cookie I know you are going to immediately eat as soon as it comes out of the oven!

Storing Tips

In an airtight container at room temperature, these cookies will stay fresh for up to 3 days. Mine never seem to last that long, though… They’re usually gone within the first 6 hours or so!

If you’d like your White Chocolate Key Lime Cookies to last even longer, place them in an airtight container and keep them in the fridge. There, they’ll stay fresh for up to 5 days. Plus, they’re pretty tasty when cooled and served with vanilla ice cream. Key lime cookie ice cream sandwich?! Yes, please!

      I’m glad you enjoyed the cookies Emily! Sadly I bought it years ago at home goods, so not sure where it’s from!

    Thank you so much for your recipe! I really like the white chocolate combined with the acidity from the lime zest. They were really good cookies. I never thought to put cornstarch to make the cookies soft. Thank you for sharing the tip.
