Preheat oven to 350°F. In a medium bowl, mix all the dry ingredients: oat flour, rolled oats, baking soda, baking powder, and sea salt.
Add the wet ingredients to the mixing bowl: grapeseed oil, brown sugar, maple syrup, flax eggs, and pure vanilla. Mix until thoroughly combined.
Mix until you get a sticky and thoroughly combined ball of soft dough. Add in cranberries and chocolate chips.
Cover the bowl of oatmeal cookie dough. Let sit for 10-15 minutes on the countertop or table—this allows the dry mixture to absorb the wet mixture and become more cohesive.
Line a baking sheet with parchment paper or greased pan.
Scoop 1-2 tablespoons of oatmeal cookie dough onto the baking sheet. Use a fork to flatten cookies into a circle—the cookies will not spread during baking.
Bake for 10-12 minutes. Allow the vegan oatmeal cranberry cookies to cool completely before eating. Enjoy!
