Generously spray a 3 quart crock pot with cooking spray. Add frozen peaches to the pot. (I did not thaw the peaches). Sprinkle the vanilla extract over the peaches. In a bowl combine the brown sugar, oats, all-purpose flour, cinnamon and nutmeg. Mix well. Cut the butter in small pieces and mix with the flour and oats mixtures. Sprinkle over the peaches. Cook on low for about 3 1/2 hours. Stir after three hours and cook another half hour.

Turn off pot, remove lid and let sit for 15 minutes. (When you go to stir your peaches if seems too dry add a little water or if using canned peaches add a little of the peach juice. I did not add any liquid to mine. Serve with ice cream or whipped cream.
