Ingredients

This Key Lime Macarons Recipe relies on precise measurements for reliable results. Use a kitchen scale if possible.

100 g almond flour, finely ground and sifted for smooth shells
100 g powdered sugar, sifted to avoid lumps
70 g egg whites, room temperature, for stable meringue
75 g granulated sugar, to sweeten and stabilize the meringue
1/4 tsp cream of tartar, optional but helpful for structure
Green gel food coloring, a drop or two for a soft lime hue

For the filling:

60 g unsalted butter, softened for a creamy texture
120 g powdered sugar, sifted
2 tbsp key lime juice, fresh for bright flavor
1 tsp key lime zest, finely grated
1/2 tsp vanilla extract, to round out the citrus notes

Pro Tips

Precision matters most in this Key Lime Macarons Recipe. First, always weigh ingredients. Even small deviations can affect shell texture. Second, master the macaronage step. Fold the batter until it flows like slow lava. If it spreads too quickly, you’ve gone too far. Third, control humidity. Macarons thrive in dry conditions, so avoid baking on humid days if possible.

Another key tip involves resting the shells. Let piped batter sit until the tops feel dry to the touch. This step helps create proper feet during baking. Finally, use an oven thermometer. Many ovens run hot or cool, and consistent temperature keeps the shells smooth and evenly baked.

Instructions

Step 1
Prepare two baking sheets with parchment paper or silicone mats. Fit a piping bag with a round tip and set it aside.

Step 2
Sift almond flour and powdered sugar together into a bowl. Discard any large bits to ensure smooth shells.

Step 3
In a clean mixing bowl, whip egg whites on medium speed until foamy. Add cream of tartar, then slowly pour in granulated sugar. Increase speed and whip until stiff, glossy peaks form.

Step 4
Add gel food coloring to the meringue and mix briefly until evenly tinted.

Step 5
Gently fold the dry ingredients into the meringue in batches. Use a spatula and fold carefully, scraping the bowl. Stop when the batter flows smoothly and forms ribbons that settle back into the bowl within 10 seconds.

Step 6
Transfer batter to the piping bag. Pipe small, even circles onto prepared baking sheets. Tap the sheets firmly on the counter to release air bubbles. Pop visible bubbles with a toothpick.

Step 7
Let shells rest at room temperature for 30 to 45 minutes until the tops feel dry.

Step 8
Bake at 300°F (150°C) for 14 to 16 minutes, rotating halfway. Let shells cool completely before removing.

Step 9
Prepare the filling by beating butter until smooth. Add powdered sugar gradually, then mix in key lime juice, zest, and vanilla until creamy.

Step 10
Pair shells of similar size. Pipe filling onto one shell and gently sandwich with another. Chill assembled macarons for 24 hours before serving for best flavor.

Variations

This Key Lime Macarons Recipe adapts beautifully. For a tropical twist, add a teaspoon of coconut extract to the filling and roll the edges in fine coconut flakes. If you prefer a sharper citrus bite, increase the lime zest slightly for bold lime macarons. You can also turn these into key lime French macarons by adding a thin layer of tart lime curd in the center of the buttercream. For a dairy-free option, use plant-based butter in the filling. Each variation keeps the signature texture while offering a fresh flavor experience.

Storage and Serving

Store macarons in an airtight container in the refrigerator for up to five days. The flavor improves after the first day as the filling melds with the shells. For longer storage, freeze assembled macarons for up to one month, then thaw overnight in the fridge.

Serve these macarons slightly chilled or at cool room temperature. They pair well with tea, coffee, or sparkling lemonade. Arrange them on a dessert platter for showers or gift them in a decorative box for a thoughtful homemade treat.
