Do you swoon for blueberries? My family can’t get enough, so we are always making these Blueberry Crumble Bars throughout the summer. They are so simple & easy to make – you can’t go wrong.

This time of year our blueberry bush is loaded with blooms. I get so excited because I know that means that our summer is going to be bursting with those little blue gems. There is something so satisfying about making a dessert from berries picked from your own garden.

There are so many different things you can make with blueberries, but these little crumble bars are just too easy. I mean, really, in about 30 minutes you can be enjoying your first bite of blueberry heaven. Why would you not want to do that – like all the time?

Can we talk about the crust for a moment? It is so buttery, like a shortbread cookie. I can’t get enough. These sort of remind me of tiny little slices of blueberry pie with the way that crust just sort of melts in your mouth.

Then there’s that crumble topping. Also very buttery, but the oats & that texture – it makes my eyes roll to the back of my head with every bite. I can’t say it enough, you will love it.

There is something just so summer about a little dessert like this one, packed with blueberries. These are absolutely perfect for picnics, potlucks & all your summer backyard bbq’s with your friends & family.

Here are some commonly asked questions

What is a Blueberry Crumble Bar?

Basically, these Blueberry Crumble Bars are a shortbread-like base for this dessert bar. It is then loaded with a layer of sweet blueberries & topped with a buttery oat crumble before being baked to golden brown perfection.

What is the best way to store these Blueberry Crumble Bars?

These are best left in the baking pan, covered with foil or plastic wrap & left on the counter at room temperature. Honestly, ours never last more than 24 hours, so they most likely won’t be there for long. My family practically inhales these.

Can this recipe be doubled?

I usually like to double this recipe but still bake it in 2 separate pans. This way I can keep the baking time the same, instead of having to figure out how much longer I need to increase the time. Plus I really like the thickness with this recipe & doubling it into another size pan would change that.

How many blueberry bars in an 9×9 pan?

Honestly, this really depends on how large or small you cut them. But I like to cut them 3×3 – totaling 9 bars. Of course, you can cut 4×4 rows for 12 bars or 2×2 & have just 4 super large bars. That is really up to you. Now I’m talking 3 bars x 3 bars (not talking measurements here).

HOW DO YOU MAKE Blueberry Crumble Bars?

1. Preheat oven to 375 degrees.
2. Line a 9×9 pan with parchment 7 set aside.
3. In mixer bowl – combine cake mix, oats & melted butter – stir on low until fully combined & crumbly.
4. Press 3/4 of the mix into your prepared dish making a nice even bottom layer.
5. Add in your blueberry syrup spreading out to evenly coat.
6. Top with blueberries.
7. Sprinkle remaining mix over the top – pressing in slightly.
8. Bake 19-25 minutes or until golden brown.
9. Cool completely before cutting.
10. Dust with confectioners sugar if desired before serving.

What baking dish do you recommend?

I really like to use this metal baking pan when making this recipe. However, I did find this super awesome silicone baking pan that I will be trying the next time I make these. It would sure make releasing the bars from the pan so easy.

Do you recommend these as a gift for the neighbors?

These Blueberry Crumble Bars make a fabulous gifts for all your friends & neighbors. We like to pick up these disposable pans for gift giving. It makes an excellent gift for the neighbors any time of year.

Everyone loves to receive a gift that brings happiness like a berry busrting dessert, right? We especially like to give these the day before a holiday. You could also gift them with the baking pan & make that part of the gift.

 

 

Can Blueberry Bars be stored in the fridge?

Yes, but make sure they are properly covered because they will tend to dry out when refrigerated. Make sure they are wrapped with plastic wrap or placed in a zip-top bag. Also, you will want to place your bars on a microwave-safe plate & microwave for 10-15 seconds before serving if you are keeping them refrigerated.

Can I make these bars without the cake mix?

You know, I have not tried making these with a cake mix substitute yet. I suppose you could make your own version cake mix with ingredients you have on hand & then use that to make these. But I’m not sure how that would turn out based on the measurements & how they are portioned into the packaging.

Can these be made gluten-free?

I have not tried making these gluten-free. However, you could try these with gluten-free cake mix & oats & see how that turns out. I would love to know, as it would make a great dessert for all my gluten-free friends.

Can Blueberry Crumble Bars be frozen?

Like most other baked goods, you can freeze crumble bars. They don’t always maintain their buttery, crumbly texture once thawed though, so make sure you properly wrap the bars & keep them airtight. Also, they may sweat when thawing, which will make them moist or wet on the outside. They will still taste the same, but might not be as aesthetically pleasing as when they were fresh.

Can this recipe be made with frozen blueberries?

Yes, but please thaw them prior to adding them to the recipe. Frozen berries tend to bake out a decent amount of liquid & this will make these bars soggy if you start with frozen berries.

To make this recipe you will need…

• yellow cake mix
• quick cook oats
• butter- melted
• blueberries fresh or frozen
• blueberry syrup
