Triple Berry Crisp

I made this Sunday and it was really really good! I took some to mom and dad and they loved it too.

Ingredients:
1 1/2 cups blackberries
1 1/2 cup raspberries
1 1/2 cup blueberries
4 tablespoons white sugar (I used more)
2 cups all-purpose flour
2 cups rolled oats
1 1/2 cups packed brown sugar
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1 1/2 cups butter

Directions:
Preheat oven to 350 degrees F (175 degrees C).

In a large bowl, gently toss together blackberries, raspberries, blueberries, and white sugar; set aside.

In a separate large bowl, combine flour, oats, brown sugar, cinnamon, and nutmeg. Cut in butter until crumbly. Press half of mixture in the bottom of a 9x13 inch pan. Cover with berries. Sprinkle remaining crumble mixture over the berries. Bake in the preheated oven for 30 to 40 minutes, or until fruit is bubbly and topping is golden brown.
