Oreo Stuffed Peanut Butter Cookies

1 Preheat your oven to 375 degrees F and line a baking sheet with parchment paper.
2 Combine the ground flaxseed and water in a large bowl and let it sit for 5 minutes to thicken.
3 Add the remainder of the ingredients into the bowl except for the Oreos and stir until combined.
4 Using your hands, divide the dough in half and form two equally sized dough balls. Flatten each dough ball to about 3 inches thick wide - just enough to place the Oreos in the center and push/fold the dough around it and make a cookie shape. Once done, place each cookie on your baking sheet.
5 Drop the temperature of the oven down to 350 degrees F and bake for 16-18 minutes or until the edges start to turn golden brown. Let the cookies cool completely on the baking sheet before enjoying.
