In this video from MrSimpleChef we learn how to make a simple apple crisp. First preheat the oven to 350 degrees. Grease up a casserole dish. Peel, core, and slice apples to half fill the bowl. He's using 4 or 5 medium-sized apples. Add all the apples into the bowl. Add 2 to 3 tablespoons of sugar. Add 2 teaspoons of cinnamon. Take a fork and stir it all in so the apples are coated with this mixture. With the apple base put aside, blend together 1/2 cup margarine, 1/2 cup brown sugar, mixed until smooth and creamy, add 1/2 cup flour and 1 cup of quick oats. Blend this and that's your topping. Put the topping over the apples. Spread it out and pack it in a bit. Sprinkle cinnamon over the top and put in oven for about an hour.
