The Coconut Macarons

These coconut lime macarons start with the best coconut flavored macaron shells! The coconut flavor is very light, just the perfect amount to complement the lime fillings! For the coconut flavor, I use 1 tsp coconut extract, adding it to the egg whites. If you want more coconut flavor, just increase the amount of extract from 1 teaspoon to 2 teaspoons.

Make sure to let the coconut macarons cool completely before filling them with the lime buttercream and lime curd.

How to Make Macarons

French macarons can seem quite intimidating to make but once you have the process down, you’ll love making them! Here are few tips to help you with baking and enjoying these lime macarons perfectly every time!

  • Whisk the egg whites just until they reach stiff peak stage, this usually takes about 4 minutes. Under mixing will result in a flat batter; over mixing can cause the cookies to spread while baking.
  • I like to use the fold and flatten method. Fold the batter thoroughly, flattening the egg whites against the side of your mixing bowl. BUT, be careful – you don’t want to over mix the batter! That will also cause your cookies to be just flat, shapeless disks.
  • If you don’t mind gluten in the recipe and you’re really struggling to get a perfect macaron, try adding 1 tbsp of all-purpose flour to the almond flour. It helps keep the macarons full inside and helps keep their shape.
  • Allow the coconut macarons to REST! Let the cookies stand for an hour at room temperature, allowing a thin shell to form on the outside. This shell gives the coconut cookies their shape so it’s crucial! If your macarons are cracking on top, you might need to let the cookies rest longer. If you live in a humid climate, extend the timing even more as humidity and moisture will prevent a shell from forming.
  • If you are baking colored or white macarons on parchment paper and want to avoid a burnt or yellow bottom, line the bottom of pan with a silicon mat. I prefer to bake on parchment paper because I get better results but every oven bakes different so try both methods!
  • I recommend keeping these refrigerated for 1 to 3 days to allow the macarons to ‘mature’. When they ‘mature’, the shells become softer and even more delicious! Take them out at least 30 minutes to an hour before enjoying to allow the cookies to thaw and come up to room temperature.

Lime Buttercream Filling

I opted for not one but two lime fillings for these lime macarons! This first filling is a zesty and fluffy lime buttercream, based on my Lemon Buttercream recipe. This buttercream is so delicious and flavored with lime extract, citric acid and lime zest. Citric acid is added to sour candies to make them sour, but it’s also great in the everyday kitchen for dessert recipes!

For these cookies, I used a reduced recipe (listed in the recipe box). Check out my in-depth tutorial for making this buttercream!

Lime Curd Filling  

The second lime filling for these coconut lime macarons is a zesty and creamy lime curd! I used my Easy Lemon Curd recipe and simply replaced the lemon juice with freshly squeezed lime juice! I cut the recipe in half since the original one makes quite a bit of curd! Try adding lime zest and green food coloring (but not too much!) for flavor and color! The lime curd needs to cool completely before being used in this recipe! You can even make the curd the day before, or a few days before, and keep it stored in the refrigerator.

I have a separate video recipe for my lemon curd! Check out the video recipe for in-depth, step-by-step instructions!
