Blueberry Crumble Bars are a delicious layer of blueberries sandwiched between sugar and butter!
Blueberry season has arrived here in Oregon! We move pretty quickly from season to season around here, starting with strawberry season, then raspberry and now blueberry! These blueberry crumble bars taste just like a eating a delicious slice of blueberry pie.
How to Make Blueberry Crumble Bars
- Just like the blueberry muffins I shared before, these bars can be made with fresh or frozen berries in a 9 x 13 pan. If you use frozen berries, just thaw and drain them really well. Making this crumble bars with frozen blueberries allows you to enjoy it all year long. The berries are coated in sugar, cornstarch and lemon juice. The cornstarch helps to thicken the mixture as it cooks.

- These blueberry crumble bars start with a layer of sugar,flour and butter that has been mixed together to form a crumble mixture, half of the mixture goes on the bottom of the pan. Add the berry mixture on top of it and then add the remaining crumble mixture on top!
- Bake at 375 degrees F for about 45 minutes or until they are nice and golden brown. Allow them to cool before slicing. You can put them in the refrigerator if you need them to cool faster. You can slice them warm but they will be easier to handle and slice if they have cooled.
Blueberry Bars are just like eating a slice of blueberry pie in a bar form. The only thing missing is a scoop of ice cream. So add a scoop of ice cream to the top of a bar and enjoy! Or maybe in between two bars for a blueberry ice cream sandwich!?!?!

Quick question as I am in the processing of making the Blueberry Crumb Bars. Salted or unsalted butter? Do you typically find there is much of a difference in “baking”?
Merci!

Cat,
I tend to always use salted butter and then cut back on the salt a bit. I haven’t noticed a huge difference when I use salted vs. unsalted. Let me know how you like the bars and enjoy!

These look yummy. We have a dozen or so blueberry bushes in our back yard. Here in NC they produce the whole month of July. My husband was away the whole month on a mission trip so I had to pick almost all of them. Some of my neighbors did pick some. I froze over 30 quart bags and gave away a bunch too.
My husband made a blueberry cobbler today. For breakfast every morning I have been having blueberries topped with vanilla yogurt, a sprinkle of brown sugar and granola. Love it.

I love blueberries but the fresh ones are darn expensive here in Utah. I found an amazing deal on them ($2/pound), and bought fresh ones for the first time ever. Heavenly! I just made a blueberry cream cheese ice cream that was to die for! I will be posting the recipe on my blog soon.
These bars look fabulous, I will have to try them with my frozen berries.
