Preheat oven to 350 degrees F. Spray 6 (8 oz) ramekins with cooking spray and set aside.
In a small bowl, combine the cinnamon and sugar. Take a tortilla and spread a thin layer of butter on both sides. Sprinkle the cinnamon sugar mixture over both sides of the tortilla. Continue until you have completed all of your tortillas.
Carefully place the tortillas into the prepared ramekins. Press the tortillas down into the ramekins and press against the sides. The tortillas will fan up and out of the ramekins and that is ok. Just make sure there is an opening in the center.
Place the ramekins on a large baking sheet and bake for 17-20 minutes or until tortillas are golden brown and crisp. Let the tortilla bowls cool for 2 minutes in the ramekins and then remove. Place the tortilla bowls on a wire cooling rack and cool completely.
To serve, fill the bowls with ice cream and berries. Serve immediately.
Note-You can make these bowls 2 days in advance, just keep in an air tight container. If you don't have ramekins, you can use oven safe bowls. You can fill the tortilla bowls with your favorite ice cream, frozen yogurt, sorbet, or even yogurt. Top with your favorite fruit or ice cream toppings.
