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.
- If you’d like some tips on freezing berries check out my post on how to freeze berries here.
- 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!?!?!

I love, love blueberries! I’m so mad that you can’t grow them in Utah 🙁 These bars look amazing; I need to make them asap. One of my favorite ways to eat blueberries is simply frozen, straight out of the freezer. They are cold and sweet and very refreshing. I also love putting blueberries in my Kix cereal. They are both spheres which makes it fun to eat. So delicious!

I soooo wish I had come across this recipe earlier this summer when I was picking blueberries like mad!!! What a beautiful looking recipe! Do you think I could use frozen bb’s in place of fresh?
Leigh Anne says
I think frozen would work fine just be sure they are well drained. Enjoy!

Just finished making these for my Bible study group tomorrow and I have to keep my husband and kids away. They smell and taste yummy! Hopefully there will be enough left for the ladies at church to try too 🙂
Thanks for the recipe!

Cat,
I am a total believer in real butter. I try to eat “real food” as much as possible. There’s a great book out called Real Food that I have enjoyed. Glad you enjoyed the bars and I am sure you could definitely add some more sugar if you wanted them sweeter. Thanks!
Cat says
Well the bars are still a little warm but I ate them anyway (I’m not a fan of warm bars usually). I enjoyed them but wondered if l/2 cup of sugar was really enough. Maybe I’ve just become accustomed to SWEET things. Did you think it needed a wee bit more? I guess I usually put ice cream on things like this and maybe that’s why – I had no ice cream. I’m trying to lose weight so no ice cream. While I’m at it – I am wondering with the big push to eat healthier (code for less fat and sugar) do you always bake with butter? I was using BECEL (not sure you have that) – it’s a transfat free soft margarine (bakes and cooks well). Of course, some people complain that it’s “one molecule away from plastic” and tell you to use butter, the next group of people tell you to use BECEL (dieticians and friends that are watching their calories). What does one do? Cat
