Preheat the oven to 325°F. Line a baking sheet with parchment paper.

In a medium bowl, combine the almond flour and baking powder. Stir in the almond butter, maple syrup, almond milk, and almond extract.

Roll the cookie dough into 18 balls. Arrange on the prepared baking sheet and gently press each dough ball to flatten slightly to 1/2-inch thick.

Lightly press 1 almond, if using, into the center of each cookie.

Bake for 12 minutes, until the cookies are golden brown. Cool on the baking sheet for 2 minutes, then transfer to a wire rack to cool completely.
