Preheat oven to 350F while you prepare the batter.

Prepare your flax egg by combining 1 tbsp flax meal with 3 tbsp water and allow to sit until thick.

In a large bowl, combine oat flour, baking powder, cinnamon and salt. Whisk until smooth.

Next add flax egg, maple syrup, pecan butter, chopped pecan pieces, vanilla extract, and mix until a dough forms. 

Roll dough into balls, about 1.5 tablespoons in size, and space out evenly on a lined baking sheet.

Top with additional whole raw pecans for garnish.

Using the bottom of a drinking glass (or other flat surface), press down on the cookie dough balls to flatten out a little bit. Create cookie like shapes, because the dough won't spread too much in the oven.

Bake cookies for about 10-12 minutes, or until firm and slightly golden brown around the edges. If you prefer a crispier shortbread, feel free to bake for an additional 1-2 minutes.

Let cookies cool and firm up and enjoy!
