Start by making the flax eggs and letting them sit to thicken.
Blend the oats until you have a mixture of oat flour and small pieces.
Combine the dry ingredients in a bowl and set aside.
Cream the vegan butter and sugars until fluffy, then add the flax eggs, molasses, and vanilla extract.
Mix in the dry ingredients until just combined, then chill the dough for at least 30 minutes.
Preheat the oven, scoop the dough onto a baking sheet, flatten slightly, and bake.
Once cooled, make the icing, dip the cookies, and let them dry.
