In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Set aside.

In a large bowl, beat the butter and sugar until combined.

Add the egg and almond extract to the butter mixture and beat until well combined.

Add the flour mixture to the butter mixture and mix together. The dough will be crumbly.

Knead the dough together and then shape into 2 logs about 10-12 inches long.

Wrap logs in wax paper or plastic wrap and let chill for 2 hours in the refrigerator.

Once chilled, preheat the oven to 325 F and line a baking sheet with parchment paper. Blanch almonds, if needed.

Remove dough from fridge and cut the dough into pieces about ¾ inch wide.

Roll each piece into a ball and place onto prepared baking sheet. Press an almond into the center of each ball.

Brush each ball lightly with the egg wash.

Bake for 15-18 minutes, until edges are golden brown.
