For the Shortbread Base

  • ¾ cup butter
  • cup sugar
  • cups flour

For the Blueberry Compote

  • 2 cups blueberries fresh or frozen
  • 1/2 cup sugar
  • ¼ cup water
  • 1 tablespoons rounded corn starch

For the Graham Crumble Topping

  • 1 tsp baking powder
  • ¾ cups graham cracker crumbs
  • cups flour
  • cup brown sugar
  • ½ cups butter cut in small cubes


To make the shortbread base

  1. Combine the butter, sugar and flour until the butter is fully incorporated in the flour. You can do this with your fingertips or pulse it together in a food processor if you like.
  2. Press into the bottom of a greased and parchment paper lined 9×9 inch baking pan. Bake for 15 minutes. Remove from oven

To make the Blueberry Compote

  1. Bring the berries and sugar to a gentle boil.
  2. Mix the corn starch with the water and add slowly to the boiling berry mixture stirring constantly.
  3. Boil gently for 1 additional minutes stirring constantly.
  4. Cool for several minutes, stirring often, while you prepare the crumble topping.

To prepare the crumble topping

  1. In a large bowl, toss together the baking powder, graham cracker crumbs, flour and brown sugar.
  2. Using your fingers, rub the butter thoroughly through the dry ingredients.
  3. Spread the blueberry compote on top of the shortbread layer.
  4. Press the crumble mixture together in handfuls so that it holds together and break off chunks of crumble all over the top of the prepared blueberry compote filling.
  5. Press down very lightly and bake for about 20-25 minutes at 350 degrees or until the top is golden brown.

  6. Cool completely in the pan before cutting into squares or bars.

  7. This cookie bar recipe is freezer friendly too.
