Preheat oven to 350. Line a baking sheet with parchment paper.
In a mixing bowl, stir together the all purpose gluten free flour, oat flour, baking soda and salt. Set aside.
In a separate large mixing bowl, use an electric mixer (or use a standing mixer) and beat together the butter (or coconut oil) at a medium speed until well combined, about 1 minute. If using coconut oil, you may need to combine using your hands if it's not coming together easily.
Beat into the wet mixture the almond butter and vanilla extract on medium speed and mix until combined - about 1 minute.
Add in the egg and mix on low until all ingredients are well incorporated.
Stir in the flour mixture into the wet mixture and mix until well combined. Fold in 1 cup of the chocolate chips into the wet mixture.
If you used brown sugar in this recipe, skip this part and move onto the next step. If you used coconut sugar, place the bowl in the refrigerator until the dough is firm, about an hour.
Roll the dough into 28 balls. Take the remaining ¼ cup of chocolate chips and press into the balls.
Place the balls 3 inches apart on the cookie sheet. Bake for 14-16 minutes until the surface of the center of the cookie no longer appears wet.
Let the cookie cool before moving them to a wire cooling rack. Store at room temperature.
