In a large bowl, cream the butter and the coconut sugar. Then add the peanut butter, gradually creaming after each addition until light. Add the egg, almond milk, and vanilla, and mix thoroughly.
In a large mixing bowl combine the flours, baking powder, soda, and salt.
Add the dry ingredients to the wet ingredients. Mix with a spatula until are the flour is incorporated.
Using a cookie scoop drop 12 dough balls equally apart onto a prepared cookie sheet. Dip fork in flour and press the cookies in a criss-cross pattern.
Sprinkle with additional coconut sugar or turbinado sugar, optionally.
Bake in the preheated oven for 8-10 minutes, or until the cookies are just set and the edges are beginning to turn golden.
Repeat the process with the second batch of cookies.
Let the cookies cool for 5 minutes on the pan before removing and placing on a wire rack to finish cooling.
