Combine strawberry filling ingredients in a bowl and set aside.
In a separate bowl combine topping ingredients. They will become a crumbly consistency.
In a 9x13 casserole dish evenly spread the strawberry filling.
Cover the strawberry filling evenly with the crumbly topping.
Bake for 35 minutes. You will know it is almost cooked when it bubbles up on the sides and begins to brown. This is key to make sure the crumble is not too wet.
Take out the casserole dish and sprinkle half a cup of crumbled Cinnamon Toast Crunch on top. Return to oven for five minutes.
Rest for at least 15 minutes. I recommend chilling overnight to get a good thick consistency.
Serve with ice cream and enjoy!
Notes
*my strawberries were smaller. If they are larger slice them into bite size pieces.
