Ingredients
  

Blueberry Filling

  • 3-4 cups blueberries
  • 1/2 cups sugar
  • 1 tablespoon cornstarch
  • 1 tablespoon lemon juice

Crust

  • 1 1/2 cups all-purpose flour
  • 1 cup finely ground cornmeal
  • 3/4 teaspoons salt
  • 1 cup butter at room temperature
  • 3/4 cups sugar
  • 1 teaspoon vanilla

Instructions
 

Blueberry Filling

  • Preheat oven to 350.
  • Butter or grease a 9-inch square pan.
  • Combine blueberries, sugar, cornstarch, lemon juice and a pinch of salt in a 2-quart saucepan over medium heat.
  • Stir until mixture comes to a boil, reduce heat and continue to simmer, stirring constantly until it thickens slightly. Remove from heat and set aside.

Crust

  • Stir together flour, cornmeal, and a pinch of salt and set aside.
  • Cream softened butter and sugar in a bowl until it is light and fluffy, then add vanilla and mix.
  • Add dry ingredients on low speed being careful to scrape the sides of bowl several times.
  • Stop mixing when ingredients are fully incorporated but dough is still crumbly.
  • Evenly distribute 1 1/2 cups of the crumbly dough over bottom of prepared pan and press lightly to hold in place.
  • Put the remaining dough in the refrigerator.
  • Bake crust for 25 minutes, or until lightly toasty brown.
  • Spread 1 1/2 cups blueberry filling over crust and crumble the remaining dough over the top of filling.
  • An even covering will produce a crust that covers blueberries almost entirely, letting it peak through here and there.
  • Put back in oven and bake until top crust is golden brown, about 40 minutes, rotating the pan halfway through the baking time.
  • Remove from oven and cool on a rack for 10 minutes then carefully run a knife around the edge of the pan to prevent the bars from sticking.
  • Cool completely and cut into bars.
