Fresh Key Lime Macarons
Key Lime Macarons are the perfect tropical inspired treat! I adore macarons, but whenever I see them in a bakery they are so crazy expensive.
Surprisingly, they are not that hard to make! As almond flour is used, that part of the recipe is a bit more expensive, but these little pieces of heaven are so worth it.

Don’t buy macarons when you can do it yourself. These Key Lime Macarons are perfect for a summer dessert, and would also make a lovely gift delivered in these pretty bags.
What You Need to Make Them
Key Ingredients
Almond flour – this is what gives macarons their chewy texture.
Key Lime juice and zest – give the cookies that luscious Key Lime flavor. You can use regular limes, but Key Limes are better if you can find them.
Eggs and unsalted butter – make the Key Lime curd filling inside creamy and rich!
How to Make The French Macarons
Place the almond flour and powdered sugar in a food processor and run for 2-3 minutes on medium speed, occasionally scraping the sides with a rubber spatula.
Sift the mixture into a large bowl. Set aside.
In a large metal bowl, add the large egg whites and cream of tartar.
Whip on medium-high using a mixer with whisk attachment or in the bowl of your stand mixer until the eggs become frothy and white. (I love this mixer as it has a compartment for all the attachments!)
Scrape the bowl, and add a tablespoon of granulated sugar, whipping for 40 seconds, repeating until all sugar is used.
Continue to whip at medium-high just until stiff peaks form.
Add the lime zest and a few drops of yellow and green gel food coloring.
Sift about one third of the dry ingredients into the bowl.
Gently fold the egg whites.
Repeat until the all the sugar flour is mixed.
DO NOT OVER MIX the egg mixture with the almond powder sugar mix it will destroy the consistency of the batter.
Spoon into a pastry bag prepped using a 1 inch round tip and pipe circles onto a cookie sheet that you cover with parchment paper.
Lightly tap the baking sheets again a flat surface to release any air bubbles and level out the batter.
Place the macarons to the side to rest for 20-60 minutes.
Bake in a 300 degree oven for 13 minutes.
How to Make the Key Lime Filling
Add eggs, sugar, salt, juice, and zest in a saucepan away from the heat.
Whisk the ingredients together until smooth.
Place on low heat, stirring often until the mixture thickens, about 4-5 minutes.
Add the butter, stirring until smooth.
Remove from heat and spoon into jars. Set aside.
Assembling the Cookies
Take half of the macaron shells and flip them upside down where the flat surface is facing up .
Using a small spoon or a pastry bag, place a small amount of curd on the cookie, filling it enough to where the curd covers ¾ of the cookie, leaving edges of the cookie visible.
It’s a good idea to fill all the cookies before adding the second macaron cookie on top, to make sure you have even amounts.
Lightly place another cookie on top with the flat edge on the curd.
Place the cookies in the refrigerator until serving.
Top Tips
It’s important to fold when adding the flour to the egg whites. Folding is scraping the sides to the bottom of the bowl and then back over the top until the sugar and flour is incorporated.
It’s also really imperative that you don’t overmix egg mixture with the almond powder sugar as it will destroy the consistency of the batter.
Variations
Once you’ve made your first macaron recipe, you will start thinking of other variations to try – and there are so many!
You could even add a dollop of meringue and a sprinkle of graham cracker crumbs to these this delicious recipe to make Key Lime Pie macarons!
A little coconut extract added to this recipe would be amazing as coconut and lime pair so well.
You could make these cookies with mint extract and a chocolate filling. Any kind of citrus, like lemon or orange, would be delicious with this same filling.
Raspberry or strawberry macarons with white chocolate or vanilla filling would be amazing in this bite-sized delicacy.
