In a large bowl, mix together all of the ingredients for the filling. You may need to let the berries thaw for 5-10 minutes and stir until the remaining ingredients stick to the fruit
In a separate bowl, make the crisp topping. Mix together all of the ingredients until it resembles wet sand
Pour the crisp filling into a pie dish
Sprinkle the topping evenly over the top
Bake the crisp at 350 degrees for 50-60 minutes, or until bubbling and the top starts to brown
Allow to rest for 10-15 minutes
Serve with ice cream
Notes
The crisp topping is best served right away. Leftovers will not be quite as "crispy", but still delicious.
