I found this recipe below from Martha Stewart, and I want to try it! It looks easy enough I can even have my girls help me in the kitchen. Although, they'd probably just eat all the berries when I wasn't looking...Blackberry Crumble
4 cups fresh blackberries (about 14 ounces)
1/4 cup sugar, plus 1 tablespoon
3 tablespoons all-purpose flour
3 tablespoons fresh lemon juice
3 tablespoons unsalted butter, softened, plus more for ramekins
1/4 teaspoon ground cinnamon
Pinch of salt
6 store-bought sugar cookies (about 2 ounces), coarsely crushed
1/4 cup rolled oats
Preheat oven to 375. Stir blackberries, 1/4 cup sugar, 2 1/2 tablespoons flour, and the lemon juice in a bowl; set aside.
Put butter, cinnamon, salt, and remaining tablespoon sugar into a small bowl. Stir vigorously with a rubber spatula until creamy. Stir in cookies, oats, and remaining 1 1/2 teaspoons flour.
Work mixture through fingers until it forms coarse crumbs ranging in size from peas to gum balls.
Butter four 5-ounce ramekins (about 3 1/2 inches in diameter). Divide blackberry mixture among ramekins; transfer to a rimmed baking sheet. Sprinkle with crumb topping.
Bake until juices are bubbling and topping is golden brown, 20 to 25 minutes. Let cool on a rack 20 minutes before serving.
