Preheat the oven to 350°F (175°C).
In a mixing bowl, combine the almond flour, powdered sugar, and salt.
In a separate bowl, whisk the egg whites until frothy. Add the almond extract and continue whisking until soft peaks form.
Gently fold the egg whites into the dry mixture until just combined.
Using a pastry bag or spoon, drop small mounds of the mixture onto a baking sheet lined with parchment paper, spacing them about 1 inch apart.
Press a whole almond into the center of each mound.
Bake in the preheated oven for 12-15 minutes, or until the edges are lightly golden.
Remove from the oven and let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
