Preheat your oven to 350°F (175°C).
In a medium bowl, whisk together the almond flour, powdered sugar, and salt.
Add the almond extract and softened butter to the bowl. Mix until well combined and a dough forms.
Line a baking sheet with parchment paper. Roll the dough into 1-inch balls and place them on the baking sheet.
Gently press down on each ball with the palm of your hand to flatten slightly.
Top each cookie with a few sliced almonds.
Bake for 12-15 minutes, or until the edges are golden brown.
Remove from the oven and let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Enjoy your delicious almond cookies!
