Saskatoon Crumble Bars

Preheat the oven to 375 F.

In a large bowl, stir together the flour, sugar, brown sugar, baking powder, and lemon zest. Add the vanilla, egg, and butter cubes. Use a pastry cutter, or two knives, to cut the wet ingredients into the dry ingredients until crumbly. There should be visible tiny lumps of butter.

Line a 9″x13″ baking dish with parchment paper. Transfer a little more than half of the flour mixture to the baking dish and press the base lightly with your hands so that it covers the bottom of the pan.

In a separate bowl, combine the Saskatoon berries, sugar, and cornstarch. Mix well until the berries are coated. Pour the Saskatoons over the base and sprinkle any of the cornstarch and sugar that may have settled to the bottom of the bowl over the berries.

Crumble the remaining butter/flour mixture evenly over the berries. Bake for 40-45 minutes, or until the top is lightly browned. Remove from the oven and allow the cake to cool before cutting it into squares.
