Preheat the oven to 350 degrees
Beat the sugar, molasses and oil on medium speed with a hand mixer or in a stand mixer until well-combined
Add the flax seed mixture, applesauce and vanilla extract and mix for another 2 minutes.
Add the flour mixture and mix until the batter is smooth.
Stir in the oats and the nuts and mix well.
Grease a cookie sheet. Drop heaping tablespoons of the cookie batter on the sheet (this recipe makes 36-40 cookies). Bake about 10 minutes, rotating the sheet halfway through the baking.
Remove from the oven - the tops of the cookies should be very lightly browned. Let the sheet stand on a rack for 2 minutes, then remove the cookies from the sheet and transfer to a rack to cool completely.
