Best Ever Blueberry Apple Crisp - cooking recipe

Ingredients

3 -4 apples, peeled and cut into chunks
4 -6 cups blueberries
1/2 cup sugar (depending on tartness of fruit) (optional)
Topping
1 cup flour
3/4 cup brown sugar
1 cup rolled oats
1 teaspoon baking powder
1 teaspoon cinnamon
1/4 teaspoon salt
1/2 cup butter

Preparation

Choose baking dish. Add enough blueberries to come 1/3 to 1/2 up the dish, keep in mind that the blueberries will \"shrink\" when cooked.
If frozen, thaw them slightly. Flour could be added to thicken the frozen blueberries if desired. Add sugar if the fruit is tart, but the topping is sweet enough that it is not needed. Cut enough apples (depending on size) into the blueberries to give colour -- making sure that you have enough room for the topping
Topping: Combine flour, brown sugar, rolled oats, baking powder, cinnamon and salt. Mix well. Cut butter into flour/oat mixture until coarse crumbs.
Spread over apple/blueberry mixture and bake in 350 oven for 30 minutes or until the fruit is cooked.
To serve: I usually make the crisp up earlier in the day. Before serving, I put the crisp in the oven at 250 for 15 - 20 minutes or until warmed, then serve it with ice cream.
