Super quick, delicious, and you can assemble it ahead of time (just keep it in the fridge til you're ready)!
4 medium tart apples, peeled and thinly-sliced (or 1 can apple filling)
1/3 cup flour, divided
1/4 cup sugar
2 tsp. lemon juice
3/4 tsp. ground cinnamon, divided
2/3 cup old-fashioned oats
1/2 cup packed brown sugar
3 Tbsp. cold butter
*In a large bowl, combine the apples, 1 Tbsp. flour, sugar, lemon juice, and 1/4 tsp. cinnamon. Pour into a greased 9-in. deep-dish pie plate.
*In a small bowl, combine the oats, brown sugar, and remaining flour and cinnamon. Cut in butter until crumbly; sprinkle over apple mixture. Cover with wax paper. Microwave on high for 5-7 minutes or until apples are tender. Serve with ice cream and drizzle with caramel sauce.
