Preheat oven to 375°F. Butter a small casserole dish (2-3 quart).
In a medium bowl, combine the flour, oats, sugar, cinnamon, and salt and stir. Add the butter and cut it into the dry ingredients with a fork or pastry cutter until the mixture is crumbly.
Add sliced apples into the casserole dish along with the granulated sugar and spread into an even layer.
Sprinkle apple filling with the crisp topping.
Bake for 30-35 minutes until the topping is golden brown and apples are tender when pierced with a fork. Serve warm with whipped cream or ice cream.
- The best apples to use: Granny Smith, Jonagold, Jonathan, Gala, Honeycrisp and Pink Lady are all great apple varieties for baking. 6 apples should yield about 6 cups (510 grams) apples.
