Blueberry Crumble Bars

Blueberry Crumble Bars - 9

Now that summer is in full bloom and fresh berries are abundant, I’ve been making jam like crazy. As addicted as I’ve become to canning though, I still love to incorporate berries into sweet baked treats when it’s not too hot to turn on the oven. These bars are easy to whip up, and the fun part is that you can substitute the blueberries for whatever berry you like – raspberries, strawberries, blackberries – the possibilities are endless!

For the filling:

  • 3 cups fresh blueberries
  • 1/3 cup granulated sugar
  • 3 Tbsp brown sugar
  • 3 tsp cornstarch
  • 1 tsp ground ginger
  • 1 Tbsp lemon juice

For the dough:

  • 1 cup unsalted butter
  • 1/3 cup brown sugar
  • 1 tsp vanilla extract
  • 2 cups flour
  • 2 Tbsp cornstarch
  • 1 tsp kosher salt

First, measure out three cups of blueberries.

Preheat the oven to 350 degrees and grease a 9×9″ baking dish. Crush the blueberries and then pour them into a medium bowl. In a small bowl, mix together the sugars, cornstarch, and ginger. Stir the sugar mixture and lemon juice into the blueberries.

In a medium bowl, cream together the butter, brown sugar, and vanilla.

    These look great! I’ve been keeping an eye on the blackberries near my house, as soon as they ripen I’m going blackberry picking. I’ll definitely be using them in this recipe!

    These look incredible! I love things made with blueberries, but the berries themselves….not so much. This is what I’m doing with my goodies from berry picking this year!

    These were a BIG HIT at yesterday’s BBQ and today hubby and my son and I finished them off with our lunch. My teenaged son LOVES THEM! I didn’t think he would since he HATES fruit pie. He said it was because it was just a fairly thin layer of the fruit. He wants me to make these again. Thanks again for sharing the recipe.
