Well, we would be remiss if we didn’t add a Holiday treat using some delicious wild Newfoundland blueberries and these crumble bars are just the ticket. We have the best  low-bush blueberries in the world here which get particularly sweet and intensely flavoured in the short growing season.

Fresh blueberries close up.

I’ve used them to make a simple blueberry compote to fill these crumble bars with a simple shortbread-like base and a delicious graham crumb crumble topping. Another freezer-friendly recipe to make in advance of your seasonal festivities.

Ingredients
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
Instructions
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.

Is looks like there is 4 layers but only instructions for 3... is there something missing?

Nope, you are just seeing the bottom browning as an extra layer. It isn't.

These were amazing. I did change the shortbread base for one I like better from another recipe (Sally's Baking Addiction Caramel Apple Pie Bars recipe) and I subbed half of the blueberries for elderberries, which grow abundantly in Northern Colorado and I almost always have in my freezer, but the rest of this recipe is totally on point and it's the best recipe I've baked in the past year...and I bake all. The. Time. Like 3-4 times a week some weeks. My friends and colleagues were all thrilled recipients of these bars. My climbing partner even posted a photo of him and another climber munching on them at the gym wall. My boss, an avowed blueberry fanatic, absolutely loved these. Thank you.
