Bread Crust Explosion

My mom was making homemade meatballs and she made homemade bread crumbs. She was about to throw away the bread crusts, and I asked, "Can I make a concoction?"  She said "sure!" and I went to work inventing this recipe. 

Ingredients
Bread crusts from 8 slices of fresh bread
1/2 cup powdered sugar
1/2 cup caramel 
1/2 cup marshmallow cream
1/3 cup white sugar
1/3 cup brown sugar
1 1/2 teaspoons cinnamon
1 1/2 teaspoons vanilla




Instructions
Preheat oven to 375 degrees. Place bread crusts in a baking dish. Mix all other ingredients and pour on top of bread crusts.  Bake 15-20 minutes, depending on your desire for crispiness.
