Line two large baking sheets with parchment paper or Silpat mats.
Heat a small pot of simmering water over medium-low heat. Add the egg whites and granulated sugar to a heatproof bowl and set it over the simmering water.
3 large egg whites, ½ cup granulated sugar
Whisk constantly until the sugar has fully dissolved, about 2 minutes. Don’t stop whisking–you don’t want to scramble the eggs!
Once the sugar has dissolved, transfer the egg white mixture to the bowl of a stand mixer fitted with the whisk attachment. Be careful not to get any condensation from the bottom of the bowl into the egg whites.
Beat the egg whites on medium speed for 4-5 minutes, or until they reach stiff peaks. Add 1-2 drops of pink gel food coloring and mix on low speed just until it is combined; no more than 30 seconds. It’s okay if the food coloring doesn’t fully incorporate yet.
Gel food coloring
Using a fine-mesh sieve, sift the powdered sugar, almond flour, and vanilla bean powder into the egg white mixture. Discard any large lumps; don’t force them through the sieve.
⅘ cup powdered sugar, 1 cup almond flour, ¼ teaspoon vanilla bean powder
Gently fold the dry ingredients into the egg whites, making sure not to deflate the egg whites.
Once all of the dry ingredients have been incorporated, gently smush the meringue on the side of the bowl and then fold it back together.
Continue to smush and fold the meringue a few times before testing to see if it has reached the Figure 8 stage. If you can draw a figure 8 with the meringue without the stream breaking, it’s ready to pipe.
Transfer the meringue to a piping bag fitted with a small round tip (I like a Wilton #10). Pipe 1-inch macaron shells onto the tray, making sure to pipe them at least 2 inches apart. Once you’ve finished piping the first tray, hold it a few inches off the counter and drop it straight down. Drop the tray another 5-6 times, or until it looks like any large air bubbles have popped. Repeat with the second tray.
Set the macarons aside to rest at room temperature until they develop a skin– usually 25-30 minutes. The macarons are ready to bake when you can lightly tap the top without the meringue sticking to your finger.
While the macarons rest, preheat your oven to 325°F. Make sure to use an oven thermometer–the oven should be exactly 325°F when you bake the macarons. Adjust the temperature up or down as needed to achieve a true 325°F.
Bake the macarons for 12-13 minutes, one tray at a time on the middle rack. If your oven cooks unevenly, turn the trays halfway through baking. Repeat with the second tray.
Allow the macarons to cool on the tray before removing them.
