Preheat the oven to 350 ℉.
In a medium to large bowl, add the ground flaxseed and oat nog. Let sit for 5 minutes to thicken.
Add the brown sugar, oil of choice and vanilla. Stir to combine.
If the quick oats are not yet ground up, grind them up into a flour. Add to the bowl with the wet ingredients.
Add the remaining ingredients to the bowl and stir to combine.
Scoop the dough out onto a cookie sheet lined with parchment paper or greased.
Bake at 350 ℉ for 13-15 minutes.
Allow to cool 5-10 minutes so that the cookies firm up a little bit. Enjoy!
