Preheat the oven to 350 degrees F and line a baking sheet with a silicone baking mat
Prepare your flax seeds by mixing 2 tablespoons flax seed and 6 tablespoons water in small bowl. Set in fridge to firm up slightly.
In a large mixing bowl, add 2 ½ cups of oatmeal, 2 cups of flour, 1 cup canola oil, ¾ cup brown sugar, ½ cup granulated sugar, 4 teaspoons vanilla extract, 1 teaspoon baking soda, and 1 teaspoon salt. Mix until the dough is moist and all the ingredients are combined. The dough will appear somewhat crumbly.
Fold in 1 ½ cup of chocolate chunks.
Gently fold in the flax eggs, being careful to not overmix.
Using your hands, roll together two tablespoons of dough, pressing the dough firmly together. If the mixture is still a bit dry, add 1 additional tablespoon of oil and mix again.
Repeat with remaining dough.
Top with a small sprinkle of flaky sea salt.
Bake for 10 -12 minutes or until golden and slightly firm. They will appear very soft. Try not to overbake!
Remove from oven and allow to cool for five minutes before transferring to a baking rack. Enjoy!
