Blueberry Crumb Bars

It’s that time of year where everyone is obsessing with blueberries and the markets are starting to fill up with ripe & juicy fruits so I wanted to make these blueberry crumb bars!

My market haul today consisted of 3 different kinds of berries, peaches, & sugar plums; along with sweet corn, green beans, and carrots!

These blueberry crumb bars got a makeover recently. This updated recipe has been made healthier with whole grains and is still just as good as the original recipe! 

If you’re sad that you can’t find the original recipe, don’t worry, you can find it here.

Can I use strawberries or raspberries instead of blueberries?

If you have a ton of strawberries, you can turn these blueberry crumb bars into strawberry crumb bars, no problem!

The great thing about fruit & crumb bars is that you can substitute basically any fruit you have on hand or whatever fruits are in season and it will still be a gratifying seasonal dessert.

Some substitution ideas: strawberries, raspberries, blackberries, or even sliced & peeled peaches. Why not try some cherries, plums, or nectarines! Go crazy. Have fun!

Another variation for cooler weather would be to utilize the growing pumpkins.

Mix some fresh pumpkin puree and add cinnamon, clove, ginger, and allspice and there you have it… pumpkin crumb bars!

Maybe make use of the abundance of apples and pears in September. I am thinking very far ahead, aren’t I? For now, you can enjoy these blueberry crumb bars! Get to it!

Pro Tips for Making Blueberry Crumb Bars

• One of these dough cutters (affiliate link) is going to help you when you begin preparing the crust. It’s great for pies too and anything that requires pressing butter into flour. I promise you won’t be upset that you have this in your kitchen if you bake a lot.
• Using fresh blueberries will be best but you can use frozen if you find yourself in that situation. I’d defrost them beforehand though!
• Freezing these bars would be fine but they won’t be as great as if you ate them right away (or within a few days).
• You can store them at room temperature and they will be fine for a day or two.
