Healthy blueberry crumble bars made with wholesome ingredients and fresh berries. You’ll love juicy blueberry flavor paired with the sweet oatmeal crumble crust and topping!
I have been on such a blueberry kick this summer. I guess that’s what happens when your husband goes blueberry picking and brings home pounds on pounds of fresh blueberries. We actually let the berries sit out on the counter for about 24 hours, grabbing handfuls whenever we felt like it. Then I decided to turn a few into a healthy treat and ended up with these healthy blueberry crumble bars.
Goodness gracious, I’m so glad I did because I’m not kidding when I say that these little bars turned out to be one of the best things I’ve made all summer!!
They’re filled with sweet blueberry goodness, have a delicious crumble topping and taste sooo good. Plus they cut and hold together really well… as long as you let them cool before removing them from the baking pan. <– I know it’s crazy hard to wait for baked goods to cool, but it’s imperative for this recipe.
Seriously I can’t get over how good these are. I served them to Isaac and his brother for breakfast and they loved them! I had one for breakfast and one as a pre-workout snack two days in a row. They’re good warm, but I honestly like them even better cold straight from the fridge!
Fresh or Frozen Berries
I love making these blueberry crumble bars with fresh and juicy seasonal blueberries, but frozen should definitely work just as well if you don’t have fresh berries on hand.
They’re definitely a treat because they do have a bit of sugar, but they’re also loaded with good-for-you ingredients like fresh blueberries, coconut oil, oats and hemp hearts so you can feel good about indulging.
I’ve used hemp hearts in recipes here on EBF before, but just in case some of you are new to them, hemp hearts are raw, shelled hemp seeds.
Here’s what I love about these little seeds:
- They taste great — they have a nutty flavor and soft texture almost like a pine nut.
- They’re easy to use — you can sprinkle them on smoothies, salads, cereal or yogurt, eat them on their own or add them to recipes.
- They’re really good for you — Hemp Hearts are a complete protein. Per serving hemp hearts contain 10g of easy to digest protein and 10g of omega-3 + 6 fatty acids. They also have a good amount of magnesium, fiber and iron.
Like I mentioned, the bars are good at room temperature, but I think they’re best cold. If you’re taking these somewhere to share I recommend letting them chill in the fridge a bit before serving.

Healthy Blueberry Crumble Bars
Ingredients
Crumble
- 1 cup oat flour
- 1 cups old fashioned rolled oats
- ½ cup coconut sugar
- ½ teaspoon sea salt
- 6 Tablespoons coconut oil, room temperature/solid
- 2 Tablespoons hemp seeds
Blueberry Filling
- 2 cups blueberries, fresh or frozen
- zest of one lemon
- 2 Tablespoons water
- 1 Tablespoon arrowroot powder or cornstarch
Instructions
- Preheat oven to 350° F. Line a square (8x8) baking dish with parchment paper.
- Add blueberries, lemon zest, water and arrowroot powder into a saucepan. Bring to a boil over medium-high heat. Reduce heat to a simmer and stir constantly for about 3-5 minutes or until mixture has thickened and some of the blueberries have started to pop. Remove from heat and set aside.
- Combine oat flour, rolled oats, coconut sugar and sea salt in a medium mixing bowl.
- Add coconut oil to the mixture and using your hands or a spoon combine mixture until it forms into a crumble.
- Measure out ⅔ cup of the oatmeal crumble mixture for the topping into small bowl and stir in the hemp hearts.
- Add remaining oatmeal crumble mixture to the prepared baking dish and evenly press into down using your hands to form the crust.
- Pour blueberry filling on top of your crust.
- Sprinkle the oatmeal + hemp crumble on top.
- Bake for 35-40 minutes until the bars are golden brown on top and the blueberry filling is bubbling and sticking to the edges of the pan. Remove from oven and place on a wire rack to cool completely. Be patient, if you don’t let them cool before removing them from the pan they will fall apart.
- Once cool, cut into 12 bars and enjoy right away or chill in the fridge before serving. I personally like the bars chilled, after they've been in the fridge for a bit.

I’ve been adding hemp seeds to smoothies a lot lately. I can’t wait to try these bars though! I think I will make them today!
Yay! Let me know how they turn out. 🙂
I would use it in yogurt, oatmeal, sprinkles on cereal, or just eat spoonfuls right out of the package.
I loveee hemp seeds in my smoothies, and topped on my oatmeal and salads!
I’m from Manitoba (Canada) and just thought it was so cool that you were using one of our local products! Love your blog and your recipes 🙂

I’ve never had hemp seeds before so I’d have to discover some new recipes, but this one looks like a great place to start!
I would sprinkle this in with my granola and yogurt and also in my oatmeal.
I’d sprinkle these on top of yogurt or cereal.
I love Hemp Hearts! Thanks for a good recipe that incorporates them into the batter rather than sprinkling on top (my usual protocol).
I would add them to my yogurt or maybe a recipe.
My favorite use of hemp hearts is in brownies — they add a great nutty flavor! And when you add hemp protein…
Ohh! I love that idea.
If using frozen blueberries do they have to be defrosted first. Thanks.
I think you could just use frozen blueberries as is, without defrosting.

I do add hemp hearts to smoothies, and I sometimes put them in my coffee grinder. I love to use them in no-bake energy bars with nut butter, honey and protein powder, and other add in’s. I love to sprinkle them before baking mac ‘n cheese! I love to use them in meat loaf!

My favorite way to eat hemp hearts is to slice up an apple (granny smith is my favorite) and press the apple slices into a pile of the hemp hearts. Delicious!
I have had hemp protein before, but not hemp hearts!! I would make baked goods with them (like brownies), or make my own own nut butter with hemp, flax, and chia 🙂

I haven’t tried using coconut or almond flour but you could certainly test it out.

I’ve seen a lot of hemp heart cereal-type recipes that intrigue me. These bars look great too!

We have some frozen blueberries already, so making these bars are probably how we’d use them!

I always see hemp hearts in Trader Joe’s and never knew how to cook with them. These bars look delicious!

Earlier this summer I was looking to make a recipe EXACTLY like this. Sweet and satisfying, but healthy too, BUT I couldn’t find one. I think there are berries still at the market to get a batch of these going before the season ends. Brittany, these are PERFECT! xx
Our team supervisor at work is vegan. So for our team meeting, I decided to make the Blueberry Hemp Crumble Bars. I had all the ingredients in my kitchen except for the brown rice flour, but I had almond flour so I used this as a substitute. Other then this change, I followed the recipe exactly.
Our team supervisor really enjoyed the bars as well as our non-vegan team members. In fact there were no left overs by the time the meeting ended. I got wonderful compliments on the dish.
You may even get a few new followers since I posted a picture of the finished product on Facebook and some of my friends asked for the recipe. I did credit you and told them to go to your site to get the recipe.
Thank you Brittany!!
These are simple, quick to put together, & down right delicious! Will def make these again!
I made these to give to a friend and they were excellent! She loved them too. Thanks for the recipe.
In the Healthy Blueberry Crumble could you swap hemp seeds for Chia seeds? If so, do the Chia seeds need to soak first and what would the substitution ratio be for this recipe? Thank you!
Hey Crista! You can swap the hemp seeds for chia seeds. No need to soak them prior and you can use 2 Tablespoons!
We swapped the hemp seeds with Chia seeds and these crumble bars were a HUGE hit. Gone within 36 hours with only our family of 4 eating them.Not sure what this says about our family, but the blueberry crumble bars were delicious.
Ahh yay!! I think that just says they were a hit with your family and I’m so happy to hear that. 🙂 Thanks for trying my recipe and for coming back to leave a comment + star rating. I really appreciate it!
This was my FAVORITE dessert I’ve ever made and what a plus that it’s healthy! The whole pan is gone and I just made them today (the family loved it)!
Ahh that makes me so happy to hear, Carly!! I’m so glad these crumble bars were a hit. 🙂 Thanks for trying them and again for coming back to leave a comment + star rating. I so appreciate it!
Hey! Would dried blueberries from Trader Joe’s work for this recipe?
Hey Hannah. You could certainly try it with the dried blueberries but I’m nots sure it would turn out because the juice from the berries helps to make the filling. If you’re looking for a recipe to use those dried berries, you could try my blueberry muffin energy balls. They’re SO good!!
These are delicious!
Would I be able to use frozen blueberries or frozen berry blend?
Frozen should work just fine, you might just need to cook them longer because the frozen berries will release more liquid.
Was excited to try this after making your blueberry crisp recipe recently. These are SO good! I love the hemp seeds. I didn’t have any lemons so substituted a tablespoon of lemon juice and it worked great. We’ve been eating them as a dessert with some dairy free ice cream. Yum!!
Ahh that makes me so happy to hear, Alissa! I’m glad you enjoyed these bars. Thanks for taking the time to leave a comment + star rating. The reviews are super helpful for other readers, so I appreciate it. 🙂
Hi Brittany can I use oat flour? If so, would the 2 sups remain the same? TIA.
I haven’t made these yet. They look delicious. Just had a quick question, can you sub the coconut sugar with monk fruit sweetener? And would the amount be the same?
Thank you,
Tina
Hi Tina! Great question! I definteily think you can use monk fruit sweetener instead of the coconut sugar, but it’s hard to know if the amount would be the same. That said, if you’re using powdered or granulated monk fruit I would assume it’s a 1:1 sub! Always read the packaging to be sure.
I want to make this, but am wondering where the cup of oat flour goes. I read and reread the instructions and cannot find it 😊
Hey Debbie, I used one cup of oats to make oat flour and then you add it with the remaining crumble ingredients. 🙂
Wow wow wow!!!! Huge winner in our house! Love the simple recipe with only a few ingredients! Made them for a road trip and we al love them, they may not make it far. This may be my favorite EBF recipe to date. Thank you!
Woo!! This makes me so happy to hear, Jennifer! I’m so glad everyone’s been loving these crumble bars! Thanks for the review. I so appreciate it!
Would frozen strawberries work in this recipe instead of blueberries?
I bet that would work great, Carrie. You might have to bake them a little longer using frozen fruit, but let me know how it turns out for you.
