Preheat the oven to 350 degrees. Line 2 baking sheets with parchment paper.
Cream the butter, sugars and almond butter with an electric mixer until light in color, about 4 minutes. Add the egg and vanilla. Beat until well blended.
In a small bowl, whisk together the flour, almond meal, sea salt, baking soda and chia seeds. Add to the mixing bowl and stir until just combined.
Using a 1 ¾ -inch ice cream scooper, drop batter onto prepared pans. Press down lightly on the cookie with the tines of a fork, making criss-cross marks. Bake 14-15 minutes or until golden brown around the edges.
Cool on the baking sheet for 1 minute and then transfer to a cooling rack.
