It’s time for Creative Cookie Exchange reveal day again! I know, if you love cookies like I do, you probably couldn’t wait to see what we had cooked up this month. This month’s theme was “Pack for a Picnic” cookies and the timing couldn’t be more perfect with Labor Day right around the corner.

The challenge was to pick a cookie that would transport well and be a delicious finishing touch to a big picnic meal. I am always so full after a picnic that I want something light and tasty to offset all the barbecue and chips. These Key Lime Coolers fit the bill perfectly!

They are light, slightly tart but with a nice touch of sweetness from the powdered sugar. The kids always love eating them because they get powdered sugar all over the faces. I think they try to see who can get the most on them. 🙂

They also remind me of lemonade and limeade that goes so well with a picnic. And they are super easy to make with just a few limes, regular cookie ingredients and a small cookie scoop. Plus, with just a few additional add-ins, you can make them all your own.

I had two add-ins I wanted to try so I divided my cookie dough into thirds and made a little of each. The first was the basic version, full of zippy tartness from the lime, the second had a touch of basil and the third had some sweet white chocolate chips. They each had their own unique taste and were all super delicious! But, if you ask me what my favorite was, I would have to choose the original. They bring back so many wonderful memories of the Florida Keys whenever I bite into one. That is a hard flavor to beat!

And if you love lots of citrusy key lime flavor give our “Simply the Best” Key Lime Pie, Key Lime Swirl Brownies and Key Lime Cake a try too!

Hope you enjoy these little coolers, however you decide to fix them. Got any more ideas for add-ins? Leave me a comment and let me know.

  • 2/3 cup butter, room temperature
  • 2/3 cup granulated sugar
  • 2 cups powdered sugar, divided
  • 2 eggs, beaten
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon lemon extract
  • 2-5/8 cups all-purpose flour
  • 3/8 cup cornstarch
  • 1 Tablespoon baking powder
  • 1/4 teaspoon salt
  • 2-1/2 Tablespoons key lime juice (I used Nellie & Joe's Key West Lime Juice)
  • 5 teaspoons lime zest, finely grated, divided
  • Optional add-ins: 4 teaspoons basil, finely chopped (for entire recipe) or 3/4 cup white chocolate chips (for entire recipe)


  1. Preheat oven to 325 degrees. Line 3 large baking sheets with parchment paper.
  2. In a large bowl, with electric mixer, beat butter with granulated sugar and 1 cup powdered sugar until light and fluffy. Continue to beat while adding eggs and extracts.
  3. In a medium bowl, combine flour, cornstarch, baking powder and salt. Add to butter-sugar mixture, alternately with key lime juice and 3 teaspoons of zest, at low speed until well mixed. At this point you can make the cookies as is, which are your traditional coolers, or you can add either the basil or white chocolate chips.
  4. Using a tablespoon or a small cookie scoop, place cookie balls 1" apart on prepared baking sheets. You can leave as rounded balls or flatten just slightly with bottom of a measuring cup. Bake in oven for 16-18 minutes or until bottoms are lightly browned.
  5. While cookies are baking, mix 1 cup powdered sugar with the remaining 2 teaspoons lime zest in a large gallon-sized plastic bag.
  6. Remove cookies from oven and let cool for 5 minutes on baking sheets then place several in ziploc bag containing powdered sugar mixture and gently toss. Shake excess off then place on wire racks and allow to cool completely.
  7. Store in airtight container.

    All the fun with eating these cookies is getting the powdered sugar all over. At least it is for me.
  2. Jennifer Tammy says:
    I love key lime and I love cookies covered with powdered sugar, so these definitely look like a win for me! (The only problem is, it's much harder to sneak powdered sugar-covered cookies without people seeing the evidence... hmm.)
