Grease an 8 “pan. Combine 1/2 cup brown sugar, oats, flour, spices, and butter. Mix until crumbly. Mix apples with remaining ½ cup of brown sugar. Place half of the crumb mixture in pan. Evenly spread the apples over and top with the remaining crumb mixture. Bake in a preheated 350 oven for 40 minutes or until golden brown. Serve warm with vanilla ice cream or a spoonful of yogurt.
