Preheat oven to 325 degrees F.
In a medium bowl, cream together the white sugar, brown sugar, vegan butter and vanilla. Add in the chia egg mixture once it has set for 15 minutes and has a gel-like texture. For best results, use a stand mixer.
In a separate bowl, mix together the flour, baking soda, salt and oats.
Add the dry ingredients into the wet ingredients, stirring to combine until a dough forms.
Stir in the vegan chocolate chips. If the dough is not forming enough to shape into a cookie, add 1-2 tbsp more of oats as needed.
Grease or line a baking sheet with parchment paper.
Shape the dough into 10 cookies.
Place the cookies evenly apart on the baking sheet.
Bake cookies for 12 minutes. Remove from the oven and allow them to chill in the refrigerator for an hour. This step makes them even chewier!
Once they have cooled down, enjoy!
