All Tuesdays are made better with something sweet, donโt you think? Especially when itโs summer and there are so many sweet berries and stone fruits to be baking with.
Itโs 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 โsummer baking bugโโฆand Iโm not complaining one bit.
Iโm so excited to be sharing these bars today. Iโve been working on them for weeks now and finally got them just right. Sometimes recipes are easyโฆand 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 โperfectโ, 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!
Jumping right into the detailsโฆ
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 recipeโฆthe butter, the berries, and the jam.
Letโs start with the butter, as I think itโs rather important. You need to use high-quality butter here, preferably high-quality salted butter. Personally, I love using Land O Lakesยฎ Butter. You all know itโs 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 Lakesยฎ 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 Lakesยฎ? They were founded in 1921 and to this day they remain farmer-owned. Today, theyโve 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 berriesโฆI 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 โ jammy. I LOVE the combo. Itโs the secret to making these crumbs bars some of the very best. If you havenโt tried using jam in addition to fresh berries in your baked sweets, you have to trust me and give it a try.
Assembling the bars.
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. Itโs 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 barsโฆand bake. About 30 or so minutes later youโll 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, isnโt technically what youโre supposed to do, but it sure is delicious.
Iโll let you make the call on how to eat them. But you guys know me, Iโm all about warm, right out of the panโฆmaybe even add some ice cream? Yeah, that would be delicious!

I love these bars, Iโve made them a few times in the past! Such a crowd pleaser!
Tieghan I need your help! I have to make 3 batches of these bars. Would you suggest making 3 separate batches to not compromise the integrity of the recipe? Or could I triple all the ingredients and make it in a bigger baking dish. If so, what size pan?
Hey Bri,
Thanks so much for making this recipe, love to hear you have been enjoying the bars!
For this recipe, I would do 3 separate batches:) I know that’s annoying, but I think that will give you the best results.
These are surprisingly easy and sooo delicious!
Thank you SO much Kalene! I am so glad you are loving these crumb bars! ๐ xT
Thanks for the recipe! Would you recommend fresh or frozen blueberries? I feel like using frozen would make the bars ‘wetter’? Or does it really not matter? Thanks!
Hi Cam,
Both work well here, if you choose to use frozen, just don’t thaw them. I hope you love this recipe! x
Do these need to be stored in the refrigerator?
Hi Brianna,
You can store these in the fridge or on the counter in an airtight container. Please let me know if you have any other questions! xT
Love these SO much!
Wondering how browned butter would change the flavor! Should it be left to solidify before adding? Looking to add a more complex flavor to the dough itself ๐
Hey Hannah,
Awesome! Thanks so much for giving this recipe a try, so glad to hear it was a hit! Sure, I would just let the butter come back to room temp after browning:) ๐๐โ๏ธ xxT
How do you store these bars? In the fridge or no? Thanks!
Hi Marielle,
I just store these in an airtight container on the counter. I hope you love this recipe! Happy Thanksgiving! xx
These were delicious! I followed the recipe as written and everyone loved them. They are rich, but not excessively sweet or greasy, and the lemon zest helps balance the flavors very well. The amount of butter is needed otherwise I think the crust may not be as tender. Thanks for a great recipe! Btw, I live at 6,000 ft so Iโm thrilled when a baking project works out great!
Hey Patty,

Would frozen blueberries work? We got a little carried away when we went blueberry picking and my freezer is bursting now.
