Gluten Free Blueberry Crumb Bars
If you follow me on Instagram or Facebook, you’ve seen that my family enjoys blueberry picking. Especially Kelsey. Toddlers love collecting things and carrying their collections around in bags/buckets/whatever they can collect things in. If you can put something in it, they will.
So we gave Kelsey the cutest little metal pail ever and told her to put the blueberries inside. Naturally, she LOVED it. Blueberry picking is her new favorite thing. Aside from blueberry eating.
I love picking blueberries for different reasons. While it is a fun family activity, I like the money it saves me. I don’t know what the price for blueberries is at your grocery store but when it’s not blueberry season I’d have to shell out at least $4 for a half pint!
Crazy. So right now I’m taking full advantage of the $2.25/pound price tag if I pick them myself. We’ve picked about 10 pounds so far and I’m planning on picking more if they’re still available. Needless to say we have a LOT of blueberries but blueberries freeze so well and I’ll be able to use them for a while.
I make blueberry muffins for quick breakfasts a lot during the school year and they work really well with frozen blueberries. So there’s no such thing as too many blueberries in my house! Since we have an abundance of fresh blueberries, I thought I’d try a blueberry crumb bar recipe that I’ve been wanting to convert to gluten-free but didn’t want to spend a small fortune on blueberries in order to make it.
This recipe calls for 4 cups of blueberries. Good thing we’re drowning swimming in blueberries! These blueberry crumb bars are soooo good! The blueberries are sweet, the crumb topping is ah-mazing and the lemon zest lends such a nice, bright flavor. Each bite is like a little fruity flavor bomb bursting with fresh berry flavor. So freaking good. You really need to try these because you absolutely will not be disappointed.
If you’re looking for more ways to use use fresh blueberries, try my mini blueberry muffins, grain free blueberry muffins, or even my blueberry dutch baby! They’re all great fruity breakfast options!
And one more thing – I’ll let you in on a little secret… When I brought these to my parent’s house for dessert, we had them with vanilla ice cream. So if you’re into that sort of thing (and who isn’t?!), vanilla ice cream is THE way to go. They’re good on their own too. But ice cream, people. Ice cream.
Whether you choose to eat these Blueberry Crumb Bars plain or with ice cream, it’s your choice. Either way, they’re fantastic.
Choose wisely, my friends and get eating! Enjoy!

Instructions
- Pre-heat oven to 375 degrees and grease or spray a 9x13 baking dish with non-stick spray.

Could a different fresh berry also be used? I love blueberries but my kiddo has an allergy to them.
I would try with blackberries or raspberries. Strawberries might release too much juice and make them soggy.
Don’t let this recipe fool you it’s definitely a 30 minute prep with washing blueberries and zesting a lemon. And for sure at least 15 minute cleanup which you can do while it bakes…. But let me tell you this recipe is totally worth the time! YUMMY!!!
Glad you enjoyed the bars Mary!
FIVE stars delicious – rated by a family of four – one foodie teen boy, a baker girl and a celiac dad. And me, the mom. I don’t see where to rate these but my son couldn’t stop eating them. And the rest of us gobbled them up too. And they were easy to make. Thanks!
Thanks Kristin, so happy to hear how much you all loved them!
When does the xanthan gum go in?
Add it in with the flour – thanks for catching that!
Would you be able to use Coconut sugar in this recipe?
I haven’t tried it but coconut sugar would definitely alter the color and make them much darker. It could also make them a bit drier.
Made this yesterday using bobs red mill 1:1 gf flour. Turned out excellent! I love that the dough turns into a biscuit and also a crumble! Thanks for sharing!
Thanks Kristen, so glad you enjoyed them! I love that too – dual purpose dough makes it makes it much easier!
I just ate dinner and these blueberry bars are making me hungry again! I want to try this, but I don’t have fresh blueberries; would canned or frozen blueberries work better here?
You can try frozen but canned might have too much moisture. I haven’t tried these with anything other than fresh blueberries though so I can’t tell you for sure. Sorry!
