Preheat the oven to 350°F and line 2 baking sheets with parchment paper.

Whisk the flour, fine sea salt, and baking powder. In a separate bowl, whisk together the almond butter, maple syrup, and vanilla. Thoroughly combine the wet and dry ingredients. Using 2 spoons, firm the cookies into small balls (about 1 generous tablespoon) and space them 2 inches apart in the prepared sheet pans. Wet toe fingertips and press down on each cookie, smoothing the edges so each is a nice little disk. Sprinkle with just a bit I the maldon salt.
Bake until the air is fragrant and the cookies are just firm, 10-12 minutes. Let cook before serving.
