Ingredients
  

For the crust and topping
  • 1 cup unsalted butter (cold) Cold is best, not melty!
  • 2 cups all-purpose flour
  • ¾ cup granulated sugar White, simple as can be
  • ¼ tsp salt
  • ½ tsp baking powder
  • Zest from 1 lemon lemon zest (optional) Totally optional, but recommended
For the filling
  • 2 cups fresh or frozen blueberries Don’t thaw if frozen
  • ¼ cup granulated sugar for the berries Or just a big healthy pinch
  • 2 tsp cornstarch For a nice thick filling

Method
 

Preparation
  1. Preheat the oven to 375°F. Grease an 8×8 inch square pan.
  2. In a bowl, mix flour, sugar, salt, and baking powder.
  3. Cut in cold butter until the mixture resembles crumbles.
  4. Divide the dough almost in half and press the larger half into the bottom of the pan.
  5. In a separate bowl, mix blueberries, extra sugar, cornstarch, and lemon zest. Spread this mixture over the bottom layer.
  6. Sprinkle the remaining crumb dough over the top.
  7. Bake for 40-45 minutes, until the top is golden.
  8. Let the bars cool for an hour before cutting them into squares.

Notes

Using cold butter makes the bars extra crumbly. For magazine-worthy slices, chill before cutting. Add a bit of cinnamon for a warm flavor twist.
