For the filling:

2 cups blackberries
2 cups blueberries
2 cups raspberries
½ cup sugar
⅓ cup all-purpose flour
1 tablespoon cornstarch
1 tablespoon lemon juice
1 tablespoon lemon zest
1 teaspoon vanilla extract

For the topping:

¾ cup brown sugar
½ cup all-purpose flour
1 teaspoon cinnamon
¼ teaspoon salt
9 tablespoons unsalted butter, cold and cubed

For the crust:

Instructions

For the Filling

Preheat oven to 400°F.
In a large mixing bowl combine 2 cups each of blackberries, blueberries, raspberries, 1/2 cup sugar, 1/3 cup flour, 1 tablespoon cornstarch, 1 tablespoon lemon juice,1 tablespoon lemon zest, and 1 teaspoon vanilla.
Toss to combine, until evenly coated. Chill in the refrigerator until needed.

For the Topping

In a medium mixing bowl, combine 1 cup oats, 3/4 cup brown sugar, 1/2 cup flour, 1 teaspoon cinnamon, and 1/4 teaspoon salt. Using a pastry blender, cut in butter until pea-size clumps form. Place in refrigerator until needed.

For the Crust

Roll out or place a pre-made pie crust into a 9-inch pie dish. Press gently into the bottom of the pan. Flute the edge, or crimp using a fork.
Add pie filling, then sprinkle the oat flour mixture on top. It will be a generous amount.
Bake for 30 minutes. Cover with foil and continue baking for 20-25 minutes. Tent the foil at the 45-minute mark to prevent the crust and topping from getting too brown.
Remove from the oven and allow the pie to cool at room temperature for 2½ hours or at room temperature for 1 hour, then 1 hour in the refrigerator before serving.

Notes

STORE leftovers on the countertop, or in the refrigerator for a few days.

FREEZE baked or unbaked. Place it in the freezer, uncovered at first, to help it set. Once frozen, wrap it with plastic wrap and then double-wrap it in aluminum foil.

To reheat. Thaw baked pie in the fridge overnight, or on the countertop at room temperature before serving. No need to thaw an unbaked pie. Pop it in the oven, checking to see if it needs a few more minutes at the end of the listed baking time. Frozen fruit pies should last about 4 months.
