For the Crust & Crumble Topping
  • 1 cup granulated sugar
  • 1 teaspoon baking powder
  • 3 cups flour
  • 1 cup butter cold and cut into 16 pieces
  • 1 egg large
  • 1/4 teaspoon salt
  • 1 tablespoon ginger fresh and grated
  • 1 lemon large, zested and juiced, separated
For the Blueberry Filling
  • 4 cups blueberries
  • 1/2 cup granulated sugar
  • 1 1/2 teaspoon cornstarch
  1. Adjust rack to middle position and heat oven to 375 degrees F. Line 9 x 13-inch baking pan with aluminum foil, leaving overhang on all sides. Lightly spray foil with non-stick cooking spray (this will help immensely when it comes time to cut the bars).
  2. For the Crust & Crumble Topping Dough: In the bowl of a stand mixer, add 1 cup sugar, 3 cups flour, and baking powder; and give it a few pulses on low to combine. Stir in salt, grated ginger, and lemon zest. Add the butter and egg and mix on medium-low speed until the butter is well cut in and the dough resembles crumbly sand. Pat half of dough into the prepared pan.
  3. For the Blueberry Filling: In a small bowl, stir together the ½ cup of sugar, cornstarch and lemon juice. Gingerly fold in the blueberries. Distribute the blueberry mixture evenly over the crust.
  4. To Finish: Crumble remaining dough over the berries. Bake for 45-55 minutes, or until top is golden brown. Cool completely, about 2 hours. Then lift the bars out of the pan using the foil overhang and cut into squares (I cut mine into 18 squares/rectangles).
Recipe Notes

While this recipe uses fresh blueberries, you could use frozen ones as well. Do not thaw the berries, just increase the cooking time by 5-10 minutes.
Bars can be kept in an air-tight container at room temperature for up to 3 days, or in the refrigerator for up to 6 days. But trust me, they won’t last that long.
