These tangy coconut key lime crinkle cookies blend island tastes for a punchy sweet-sour snack. I've whipped these up countless times when I needed something bright during gloomy winter days, though they work just as well in summer with a cool glass of something refreshing.

These treats turned into my go-to dessert after I took them to a seaside getaway with my pals. Now they bug me to bring them whenever we get together, no matter what time of year it is.

Ingredients

  • 2 1/2 cups all purpose flour: creates the backbone for these airy treats
  • 1 teaspoon baking powder: adds the perfect amount of rise for those classic cracks
  • 1/2 teaspoon salt: boosts all the tastes and cuts through sweetness
  • 8 tablespoons unsalted butter: brought to room temp so it mixes properly
  • 1 cup granulated sugar: adds sweetness and helps form that crispy outside
  • 1/2 cup sweetened shredded coconut: gives amazing bite and island flavor
  • 2 large eggs: add richness and hold everything together
  • 1/4 cup key lime juice: delivers that zingy kick we want, fresh works best
  • 1 lime zest: split between cookie mix and coating for extra punch
  • 2 teaspoons coconut extract: kicks up the beach vibes throughout
  • 1/2 cup powdered sugar: makes that pretty white crackled look we're after

Step-by-Step Instructions

Prepare Dry Ingredients:
Mix flour, baking powder, and salt in a bowl until blended. Don't skip this basic step as it makes sure your cookies rise evenly.
Create Butter Base:
Mix butter, granulated sugar, and coconut for about 3 minutes until fluffy and light. Your mix should look whipped and bigger, which makes for softer cookies.
Add Wet Ingredients:
Drop in eggs one by one, letting each mix in fully before adding another. Then pour in key lime juice, coconut extract, and half the lime zest, beating for around a minute. Don't worry if it looks a bit lumpy now.
Combine Everything:
Slowly add the flour mixture on low speed, just until it all comes together. Stop mixing once you can't see any flour or you'll end up with tough cookies.
Chill The Dough:
Pop in the fridge for 20 minutes so the dough firms up for easier handling. This wait also lets flavors blend and stops cookies from spreading too much.
Prepare For Baking:
Heat your oven to 350°F and put silicone mats or parchment on baking sheets. Mix powdered sugar with the rest of your lime zest in a shallow dish for coating.
Shape And Coat:
Scoop cold dough into 1 1/2 tablespoon balls and roll them up. Coat each ball fully in the sugar mix. Set them on your trays about 2 inches from each other.
Bake To Perfection:
Cook for 12 to 15 minutes until they're puffy, starting to flatten, and feel set around the edges. Those nice cracks will show up as they bake and cool down.
Cooling Process:
Let them sit on the pan for 5 minutes before moving to a cooling rack. This keeps them from breaking apart while they're still soft.

When I taste key lime and coconut together, I'm instantly back in the Florida Keys where I first tried this combo. These days my little girl helps roll the balls in sugar, and seeing her tiny fingerprints in the coating makes them taste even better.

Getting The Perfect Crinkle

The trick to stunning cracks is covering the cookies completely with powdered sugar before they go in the oven. For even more dramatic splits, roll the dough balls in sugar twice, pressing lightly the second time so it sticks well. Chilled dough makes better cracks than warm dough, so take out small batches from the fridge as you work.

Storage And Freshness

These cookies stay good in a sealed container at room temp for about 5 days. The lime flavor gets a bit stronger after day one. To keep them soft, throw in a small bread slice that will stop them from drying out. If you want to save them longer, freeze cooled cookies between sheets of parchment for up to 3 months.

Ingredient Substitutions

Can't find key limes? Regular limes work fine though they're a tad less fragrant. In a rush, the bottled key lime juice works pretty well too. Want to switch it up? Try using lemon or orange instead of lime. You can swap in unsweetened coconut if you want less sugar. Got friends who can't have gluten? A good measure-for-measure gluten free flour mix works great without changing anything else.

Serving Suggestions

These bright treats go great with afternoon tea or coffee. For a fun summer sweet, put some vanilla or coconut ice cream between two cookies and freeze them for tasty ice cream sandwiches. They also work really well on fruit plates or next to sorbet after a big meal.

FAQs About the Recipe

→ Can I swap regular lime for key lime?

Absolutely, you can use regular lime juice instead, but keep in mind the flavor won't be as tangy and will taste a bit milder.

→ Can I prepare these cookies beforehand?

You bet - the dough can stay in your fridge for up to 24 hours, or you can freeze the finished cookies for about 3 months.

→ What's the point of the powdered sugar coating?

The sugar coating isn't just for sweetness - it's what gives these cookies their pretty cracked look as they bake and expand.

→ Will unsweetened coconut work too?

You can use it, but your cookies won't be as sweet. Try adding a touch more sugar to the mix if you go this route.

→ Can I try different citrus flavors?

For sure! Playing around with orange or lemon zest can give these cookies a whole new citrus personality.

What You'll Need

→ Dry Ingredients

01 2 1/2 cups plain flour
02 1 tsp baking powder
03 1/2 tsp salt

→ Wet Ingredients

04 8 tbsp soft butter, unsalted
05 1 cup white sugar
06 1/2 cup coconut flakes, sweetened
07 2 large eggs
08 1/4 cup key lime juice
09 1 lime zest, split in half
10 2 tsp coconut extract

→ Coating

11 1/2 cup icing sugar

Step-by-Step Guide

Step 01

Blend the flour, baking powder, and salt together in a bowl and put it aside for now.

Step 02

Beat butter, sugar, and coconut with an electric mixer at medium speed until the mix gets fluffy and light.

Step 03

Drop in eggs one by one, stirring well each time. Pour in key lime juice, coconut extract, and half the lime zest. Give it a good mix at medium-high for 1 minute, making sure to scrape down the sides so everything gets mixed in.

Step 04

Turn the mixer down low and slowly add the dry stuff, mixing just until everything comes together.

Step 05

Stick the cookie dough in the fridge for about 20 minutes so it's not so sticky to work with.

Step 06

Heat your oven to 350°F (175°C) and put silicone liners or parchment on your baking sheets. Mix the icing sugar with the other half of lime zest in a small bowl.

Step 07

Use a small cookie scoop (about 1 1/2 tbsp size) to make balls from the cold dough. Roll each one in the icing sugar and lime zest mix until they're totally covered.

Step 08

Put the cookies on your lined baking sheets with 2 inches between them. Bake for 12-15 minutes until they puff up, get firm around the edges, and start to flatten out.

Step 09

Leave the cookies on the baking sheets for 5 minutes, then move them to a wire rack to finish cooling off.

Additional Notes

  1. Want a stronger lime kick? Just toss an extra teaspoon of key lime zest into your dough.
