These Blueberry Crumble Bars Are Going To Be Your Favorite Summer Dessert Recipe!
If you love a good fruit dessert for the summer, and want to do something a little different than a cobbler or fruit salad, these Blueberry Crumble Bars are exactly what you’re looking for! These sweet bars are always the hit of every BBQ, party, or event, and I’m constantly being asked for the recipe!
The Crumble Topping Is Also the Crust!
What makes these blueberry bars so easy is that the crumb topping is also the crust! This makes the prep step extra easy! The crumb topping is a buttery streusel-style layer that you simply press half of into the bottom of the pan and then top with the remaining mixture.
It’s sweet and rich, with the perfect texture thanks to the rolled oats!
all purpose flour
old fashioned oats (rolled oats)
light brown sugar
Tips When Making Blueberry Crumble Bars:
What I love most about this recipe is that it’s very easy. Here are a few tips to make the process super simple!
I use my blender to combine the ingredients, but you can easily use a food processor. Or if elbow grease and a pastry cutter is your favorite method use “Quick Oats” in place of the old fashioned.
Coating the fresh blueberries in sugar and cornstarch makes a sweet filling and also thickens it up thanks to the cornstarch!
The blueberries will begin to bubble as they bake. This means the bars are just about done! Don’t over-bake the bars, as this will make the crust and the topping too hard to cut successfully. Trust me on this!
Can You Use Frozen Blueberries?
Yes you absolutely can, just thaw out the blueberries and pat them dry! This is a great recipe to make during blueberry season when they are the ripest, but frozen blueberries are a great alternate! I always buy or pick extra blueberries during peak season so I can freeze and enjoy them all year long!
How Do You Store These Blueberry Bars?
I recommend storing these bars in the refrigerator, airtight, for up to 3 days. You CAN store them at room temperature, but I would only advise doing that for 1 overnight. The moisture in the blueberries will cause the topping to get a little soggy, and the refrigeration helps slow this process!
Can You Freeze Blueberry Crumble Bars?
Yes, absolutely! These bars freeze very well! Allow them to thaw in the refrigerator, and you can enjoy them chilled, or at room temperature!
