Crisps and crumbles are great and easy desserts, fruit tossed with sugar and maybe some spices, then topped and baked. This is the best topping I have found, and you can use it for just about anything you like. This makes enough to top about 2 lbs of fruit.
1/2c flour
1/2c rolled oats
1/4c white sugar
1/4c brown sugar
1/2 tsp cinnamon
1/2 tsp nutmeg
1/8 tsp salt
6 TB butter, cold, and cut into pieces
1/2c walnuts or pecans
Put all ingredients in your food processor and zap until crumbly. Use to top your fruit, then bake as directed.
