Introducing a healthier spin on the classic blueberry crumble bars! These gluten-free blueberry bars are loaded with a fresh blueberry filling and a fiber-filled oat crumble. They’re so easy to whip up, and make for the perfect weekly meal prep.

I’ve been on a berry kick these last few weeks, but always find myself with an extra container of berries towards the end of the week, right before we head to family for the weekend. I’ve been experimenting with more breakfast bars, and decided to play around with a blueberry bar since it was one of my favorites growing up!
These bars were such a hit! I’ve made at least 3 batches so far. One thing I love about them is that they require just one bowl- no mixer involved! These bars are not overly sweet, which makes them a great option for a snack, breakfast or even dessert!
The crumble and crust are both from the same mixture, so there are only two quick steps to these bars. You’ll need a few simple ingredients, and you’ve got yourself a delicious, fruity oatmeal bar!

Ingredients you’ll need for these blueberry crumble bars
- Blueberries- I used fresh, but I think frozen will work as well since you’ll be cooking the blueberries on the stove top first
- Rolled Oats
- Oat flour
- Coconut oil
- Pure maple syrup
- Vanilla extract
- Lemons
- Tapioca flour to help thicken the blueberry mixture. You can swap arrowroot starch or cornstarch to keep them gluten-free, or regular flour if needed!
You start by mixing the crumble ingredients in a bowl, flattening half into a crust, and baking it while you cook the blueberry filling. I let the blueberries cook down on the stove with the sweetener, lemon juice, and tapioca flour, then pour it over the crust with the remaining crumble and bake it until golden brown.
You may see some recipes that bake the blueberries directly in the oven, and skip cooking them down on the stove. I prefer them less chunky, so I love this method!

You guys are going to love these gluten-free blueberry crumble bars. They’re kid friendly too, which is always a win! They’re the perfect recipe for those extra berries you have lying around.
Have made these twice now and cannot get over how good they are, especially considering how easy they are to make. My very picky son and husband both LOVE these! Definitely adding it to the list of go-to blueberry snack recipes. Thank you!!!
Thank you, Dianna! Family approval is the best ☺️
Very good and satisfying! Not too sweet so it is perfect for breakfast or a snack. WIll be trying with different fruits but blueberry is delicious.
So glad you enjoyed them, Kiki! I’ve had followers make them with strawberries and even apricots 🙂
Can I use oil instead of coconut oil?
Butter or a butter substitute would work best! Any other oil wouldn’t work as well since the coconut oil is softened and not melted
SO good!! Made them with frozen blueberries so just added extra corn starch as recommended. Huge LDW hit and so easy to make!
So happy to hear that!!
i cant wait to make it!!😻
how many grams in a cup?☺️
Hey Barbara, the amount will vary depending on what’s being measured, like butter, oats, flour and liquid. Here’s a resource I found online! https://www.allrecipes.com/article/cup-to-gram-conversions/
