Preheat oven to 350 degrees F.
Place the frozen berries, sugar, cornstarch and 1/2 cup of the crisp topping into a medium mixing bowl and stir to combine. Divide the mixture evenly between 4 (7 to 8-ounce) ramekins. Top each ramekin
with 1/2 cup of the remaining crisp topping. Place the ramekins on a sheet pan
and bake on the middle rack of the oven for 30 to 35 minutes or until the fruit is bubbling and the topping is browned. Allow the crisps to cool for 15 minutes before serving.
