Spray 2-3 cookie sheets with baking spray. In a small bowl combine flour, baking soda, cinnamon and salt. In a large bowl or standing mixer whip butter and sugar, add in egg and vanilla. Add in apple sauce and ⅓ cup of water. Now you can add the dry flour mixture, mix until just combined. Add in the oats and raisins and mix until just combined. Place in fridge for 15 minutes minimum or overnight.
Pre-heat oven to 350, using an ice cream scoop dollop out tennis ball sized (YEP!) dollops of cookie dough, give enough room for a little spreading. Bake for 15-18 minutes until golden brown.
