Super simple Cinnamon Sugar Blueberry Crumb Bars. These bars are berry-filled, extra jammy, buttery, and oh so delicious. The base is a simple salted butter crumb dough sweetened with golden brown sugar. The filling has hints of lemon and is made with fresh blueberries and blueberry jam…for the maximum berry experience. And the final buttery crumb layer is tossed in cinnamon-sugar, creating the ultimate extra sweet topping. Put everything together and you have a blueberry crumb bar that’s buttery, jammy, sweet, cinnamony, and layered with deliciousness. These bars are everyone’s summer favorite.

All Tuesdays are made better with something sweet, don’t you think? Especially when it’s summer and there are so many sweet berries and stone fruits to be baking with.
It’s funny, sometimes all I want to make are savory recipes. But then sometimes my sweet tooth kicks into high gear, and all I want to do is bake. Right now I seem to have a “summer baking bug”…and I’m not complaining one bit.
I’m so excited to be sharing these bars today. I’ve been working on them for weeks now and finally got them just right. Sometimes recipes are easy…and sometimes they require a little more time and attention. These are an example of the latter, but the added effort and multiple rounds of testing were worth it.
I could not love these simple blueberry crumb bars more. I rarely ever think a recipe is “perfect”, but these are pretty darn close.
Extra buttery, soft, sweet, gooey, filled with blueberries and hints of both vanilla and cinnamon. Honestly? These are the fruity bars you need to make this summer.
And super pretty, which I love!
As mentioned, these bars are easy to bake up and require very little prep work.
First things first, there are three very important ingredients in this recipe…the butter, the berries, and the jam.
Let’s start with the butter, as I think it’s rather important. You need to use high-quality butter here, preferably high-quality salted butter. Personally, I love using Land O Lakes® Butter. You all know it’s my go-to butter and what I use in my kitchen every day for both baking and cooking.
I love the rich buttery flavor and hints of salt in Land O Lakes® Butter. It creams wonderfully into a batter and always turns out the best brownies (like these peanut butter brownie ice cream bars) and sweet pies (like my peaches and cream pretzel pie).
A little fun fact about Land O Lakes®? They were founded in 1921 and to this day they remain farmer-owned. Today, they’ve grown into a group of more than 1,700 family-owned dairy farmers. I love that such a huge brand has remained true to its core values. To me, this makes their butter that much better.
Moving on to the berries…I really wanted them to burst in your mouth, but yet be jammy too. Enter the combination of fresh blueberries and sweet blueberry jam.
Using a combination of fresh berries and sweet jam adds so much flavor and texture. The fresh blueberries provide a burst of flavor with every single bite. But the jam makes the bars extra sweet, gooey, and yeah – jammy. I LOVE the combo. It’s the secret to making these crumbs bars some of the very best. If you haven’t tried using jam in addition to fresh berries in your baked sweets, you have to trust me and give it a try.
For the dough, just mix the butter with flour, brown sugar, and a pinch of salt. Press half the dough into a baking pan, reserving the remaining dough for the topping. Then add the berries and jam. I like to toss the berries with a bit of lemon and vanilla for added flavor.
Now, with the reserved dough, toss it with sweet cinnamon-sugar. Yes, cinnamon-sugar. It’s that extra-special touch I love to incorporate into recipes. The cinnamon creates a warming bar and highlights the sweetness and saltiness within the berries and butter.
Crumble the cinnamon-sugar dough over the bars…and bake. About 30 or so minutes later you’ll have a kitchen that smells wonderful, and bars that look even better.
These are great as a sweet breakfast, afternoon snack, or after-dinner dessert. Oh, and eating them warm, right out of the pan, isn’t technically what you’re supposed to do, but it sure is delicious.
I’ll let you make the call on how to eat them. But you guys know me, I’m all about warm, right out of the pan…maybe even add some ice cream? Yeah, that would be delicious!

Hi, everyone loved these bars. Which cookbook of yours has this recipes? Thanks
Hey Philip,
So glad this recipe was enjoyed. All of the recipes that are on the blog are not located in a cookbook, they are only available on the blog. All of the recipes that are in the cookbooks are exclusive to the books. I hope this helps! xTieghan
Yummy!Yummy! It looks sooo delicious. It must try it on my weekend.
I hope you love it!! Thank you Rozy! xTieghan
I made these last night and left to cool overnight. I cooked the allotted time and they were light brown on top. They are very sweet and have to use a fork to eat. i love the blueberry flavor. They are very rich and a little too sweet for me. I am chilling them to see if the flavor is more to my liking when cold. I may try again with less butter and no granulated sugar in the topping and more cinnamon. They looked pretty but I didn’t get the peekaboo look with the berries and I used the full 2 cups of berries. Thank you for your food blog. It gives me incentive to try new things. Everything looks amazing.
Thank you so much Rebecca!! I am so happy this recipe turned out so well for you! xTieghan
Oh my gosh…this recipe is heaven!!!! We loved it SO much! Thank you!!!!

I love how simple this recipe was!! You can’t go wrong with the flavors and it took less than 15 minutes to get it into the oven! My kind of dessert! Thank you!
Thank you Hanna! xTieghan
I made these this week, and they’re so good. I even made my own blueberry jam, which was a breeze!
Thank you so much Victoria! xTieghan
I have been on a quest for the best blueberry crumble recipe. I have to say, I am done looking. The extra thick topping layer with the cinnamon not only makes this a much more cookie like texture, but holds the blueberries together in a formal structure. I haven’t let them cool fully, so I will be interested to see if they become finger food like a bar cookie, but they are amazing warm with a fork. Tossing my other blueberry recipes for this, and will tinker with how to double it, as 8×8 is just not enough.
If you like to double the topping on blueberry crumbles and crisps, this is the recipe for you.
Hi Pam! I am glad you enjoyed this recipe! Thank you so much for trying it! xTieghan

I made these for a potluck this week, and they were a hit! I loved that they weren’t too sweet, and the lemon zest gives them the perfect amount of tartness.
Thank you so much Emily! I am so happy to hear that! xTieghan
I just made these bars and they turned out better than i expected! I knew they would be delicious, but wow! My husband took a bite and these “wow, these are good”, doesn’t sound like much, but believe me – coming from him, that means that they are out of this world delicious:)! So thanks again for yet another amazing recipe!
Thank you so much Elena!! I am really glad this recipe turned out so well for you!! xTieghan
Super yummy and easy. Went so well with vanilla ice cream to balance sweetness. Did have to cook an extra 10 minutes, but I have an extremely old
Oven. Everyone asked for the recipe! The lemon zest really helped it stand out.
Wow that is so amazing to hear! Thank you Sara! xTieghan
Positively delicious. I made in 9×9 pan and they turned out perfectly. Love the buttery topping. When I need an idea / recipe, my first choice is always Half Baked Harvest. Thank you!
Aw that is so sweet to hear! Thank you so much Mary! xTieghan
Oh my – made with wild blueberries grown in our backyard in Maine, this is incredibly delicious! Buttery and rich, with a nice tart bite from the berries and raspberry jam. Thank you for another amazing recipe!
