While I could eat Key lime flavored goodies all year, it’s when warm weather hits that I really want to dial up that citrusy flavor. These Coconut Key Lime Cookies are the perfect way to channel the tropics.
Most of you are probably familiar with Key lime pie, the treat popularized after the introduction of sweetened condensed milk in the early 1930’s. The creamy tart pie is popular all over the U.S., but not nearly as much as it is in Key West.
So, I decided to take the flavors of the popular pie and make cookies instead. After all, these brightly flavored cookies are far more portable to take to parties and cookouts. Plus, twenty-four cookies is superior to the amount of slices in a pie, right?
Are Key Limes Regular Limes?
Table of Contents
The simple answer is no. Key lime is a tad sweeter and less acidic. However, the majority of the time, regular limes can be used.
For this recipe, I do list lime juice instead of specifying the use of Key lime juice since it may be a challenge for people in some places to find Key limes or Key lime juice.
However, if you have Key limes or their juice available, you can really punch up the tangy flavor if you use Key lime juice. I have the most luck finding key lime juice in the grocery store aisle where lemon and lime juices are sold or in shops that sell cocktail ingredients.
I like munching on these cookies all on their own, but you can also grab your favorite ice cream and use them to make ice cream sandwiches or use any leftover limes to make Key Lime Pound Cake.
Why You’ll Love Coconut Key Lime Cookies
- Bright flavors– these cookies channel beach-time and are the perfect treat at any warm weather gathering.
- Easy– these cookies come together in about twenty minutes or less, and the bake time is even faster!
- Accessible ingredients– many avid bakers likely have most of the ingredients in their pantry already.
- All purpose flour– if you like to bake you probably already have this pantry staple. However, if you need to grab it from the store, any brand will do. If you have a big bag, you can store it in a cool, dry cabinet. Alternatively, it can be frozen for up to 2 years.
- Baking powder– this leavening agent helps these cookies to have a light texture.
- Salt– just a bit of regular table salt will help bring out the lime and coconut flavors in these cookies.
- Butter– since there’s salt in the recipe, make sure to use unsalted butter. Leave butter on the counter for about an hour to soften so that it mixes easily.
- Granulated sugar– this type of sugar dissolves quickly when mixing and baking. Granulated sugar will last for up to 2 years in the pantry. Make sure not to store it in the refrigerator, though, where it’s likely to get lumpy.
- Shredded coconut– you can usually find bagged shredded coconut in the baking aisle of most grocery stores.
- Eggs– you can use any eggs you might already have in your refrigerator as long as they are large size.
- Lime juice– you can certainly juice your own limes but bottled lime juice can be used as well. Please note that bottled citrus flavors tend to pack less punch than freshly squeezed. However, key lime juice will have more authentic key lime flavor when it is near impossible to find fresh key limes.
- Coconut extract (optional)- if you don’t have coconut extract on hand in your pantry, you can omit it. However, using it will help lend that extra coconutty flavor.
- Powdered sugar– this soft sugar will help to make these cookies pretty and also adds some extra sweetness.
How To Make Coconut Key Lime Cookies
- Prepare oven and pan. Preheat oven and line a cookie sheet with parchment paper. While I don’t typically use parchment paper for cookies, these cookies have a tendency to stick if you don’t use it.
- Whisk dry ingredients. In a large bowl, whisk together the flour, baking powder, and salt. Be sure to fully incorporate all 3 ingredients.
- Beat butter and sugar. In a separate bowl or stand-mixer, beat the butter and sugar until the mixture is light and fluffy. Next, stir the coconut into the butter and sugar mixture.
- Add eggs. Add each egg, one at a time to the butter, sugar, and coconut. Beat the mixture well after each egg is added. Next, add the lime juice and the coconut extract (if using) and mix well.
- Add dry ingredients. Add the flour mixture gradually, mixing it in until it is just combined.
- Scoop cookies. Scoop the cookie dough into 24 1½ inch balls. You can use a 1 ½ tablespoon cookie scoop if you have one. A melon baller will work well, too. If you do not have either of those, two spoons can be used to scoop and form the balls.
- Roll in powdered sugar. Roll each dough ball into the powdered sugar. Then, arrange the balls on the parchment paper lined cookie sheet with about 2 inches between each.
- Bake. Bake the cookies. When they are ready to be removed from the oven, their edges will be just slightly browned.
White chocolate chips- Key lime cookies with white chocolate chips have just an extra hint of sweetness. Toss in a handful or two to the cookie batter.
Icing- try drizzling powdered sugar icing over the cookies after baking for a pretty presentation.
Key lime juice- if your local grocery store has it in stock, try using Key lime juice instead of your typical lime juice for an even more floral and tart flavor.
Berries- raspberries and blueberries pair particularly well with Key lime and coconut flavors. To add berry flavor, try tossing in some dried berries before baking.
