Preheat the oven to 325°F (160°C). Line baking sheets with parchment paper or silicone liners.
Stir together the almond flour, granulated sugar, and salt.
In a separate bowl, beat the egg whites until they form soft peaks. Add the almond extract and gently fold into the egg whites.
Fold the egg white mixture into the almond flour mixture until just combined. The dough will be sticky.
Using a 1-tablespoon cookie scoop, portion the dough and roll into balls between your palms. Then roll each in confectioners’ sugar, coating well.
Place the cookies on the prepared pans, leaving about 2 inches between each cookie.
Bake one pan at a time for about 22 to 25 minutes, or until the cookies are lightly golden and the tops are cracked.
Let the cookies cool on the baking sheet for about 5 minutes before transferring them directly to a wire rack to cool completely.
Notes
To store: Place the cooled cookies in an airtight container with parchment paper between the layers to keep them from sticking together. They’ll keep at room temperature for up to 5 days.
