Easy to Bake Mix! Just add fresh apples & butter, then bake and enjoy! For an easy apple crisp, substitute 30 oz. can apple pie filling for fresh apples. Crumb apple pie: fill an unbaked 9 inch pie shell with 30 oz. can apple pie filling. Top with crumb mixture. Bake at 375 Fahrenheit for 45-55 minutes. In place of apples, try 5 cups blueberries (about 2 pints), 4-5 medium to large peaches (peeled and sliced), or 4-5 medium to large pears (peeled and sliced) and 1/2 cup raisins.
