The Best Fruit Crumble on the Planet

This is so easy to make, totally delicious, and relatively healthy as desserts go. (Shown here is strawberry-rhubarb cobbler.)

Ingredients
—approximately 6 cups of fresh fruit (this is a rough number—could be 5, could be 7). Some of my favorites are apple, apple/strawberry, pear/raspberry, apple/rhubarb, strawberry/rhubarb, and nectarine/raspberry.
—1/2 cup all purpose flour
—1/2 cup old fashioned oats
—1/2 packed light brown sugar
—1/2 tsp ground cinnamon
—5 Tbsp cold butter

• Preheat the oven to 375.
• Put your fruit into a 2 qt baking dish.
• In a bowl, mix together the flour, oats, brown sugar and cinnamon.
• Chip off pieces of the cold butter into the bowl and once it is all in the bowl, using your hands, smush it all together. it won't be perfectly or evenly moistened...it will in fact be crumbly, but mix it together the best you can.
• Crumble the topping over the fruit.
• Bake for 40-45 minutes
