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:

For the dough:

First, measure out three cups of blueberries.

Blueberry Crumble Bars - 1

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.

Blueberry Crumble Bars - 3

In another medium bowl, whisk together the flour, cornstarch, and salt.

Blueberry Crumble Bars - 2

Add the dry ingredients into the wet ingredients half at a time until crumbly.

Blueberry Crumble Bars - 4

Press 2/3 of the dough into the pan, reserving the remaining third. Bake the crust about 10 minutes or until very lightly browned.

Blueberry Crumble Bars - 5

Pour the blueberry filling on to the hot crust, and then sprinkle the remaining dough over the top.

Blueberry Crumble Bars - 6

Bake 20-25 minutes or until the crumb topping turns golden brown.

Cool before serving.

  16. 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!

  18. 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.

  32. I was a bit leary since majority of crumble bar recipes call for cutting in butter…but…I’ve made this recipe twice and it is sooo easy plus I don’t see/taste a difference. Thanks for posting!
