Preheat the oven to 350 degrees F (176 C) and line a large baking sheet with parchment paper.
In a medium mixing bowl, combine gluten-free oats, gluten-free flour blend, sea salt, baking powder, and brown sugar. Whisk to combine.
Add natural peanut butter (with only peanuts and salt), vanilla, and egg to the mixture. Stir until a tacky dough forms.
If the dough is too wet or dry, adjust the consistency by adding a little more gluten-free flour or peanut butter.
Stir in chocolate chips. Then, use a scoop to portion out the dough into 1 ½ tablespoon amounts and place on the prepared baking sheet.
Top each cookie with an additional sprinkle of chocolate chips and press down gently to form a disc shape.
Bake the cookies for 10-12 minutes, or until they are lightly golden brown around the edges and have expanded to about twice their original size.
Remove from the oven and let cool on the pan for 10 minutes. If desired, sprinkle with a small amount of salt at this time.
Once cooled, enjoy the cookies with your preferred dairy-free milk.
Store them in an airtight container at room temperature for up to 4-5 days, in the refrigerator for up to 1 week, or in the freezer for up to 1 month
