It’s that time of year where everyone is obsessing with blueberries and the markets are starting to fill up with ripe & juicy fruits. My market haul today consisted of 3 different kinds of berries, peaches, & sugar plums; along with sweet corn, green beans, and carrots! The great thing about fruit & crumb bars: 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, berry crumb bars! Get to it!

    Is the white sugar listed in the recipe powdered sugar or is it the same cane sugar use in the beginning of the recipe?

    • Samantha replied on — August 1st, 2012 at 11:32 am

      Both sugars listed are white cane sugar. Sorry for any confusion.

    Made these last night–they were great. I’m desperately trying to use up all the fruit I seem to have on hand. Added juice of 1/2 a lime to the blueberry layer, skipped the cinnamon and added teaspoon of vanilla to the pastry. Officemates scarfed the whole lot of them down this morning–they were a hit. Thanks for posting 🙂

      Glad you made them! Your adaptations sound lovely!

    Is the butter to be room temp or refrigerator temp?

    • Samantha replied on — August 13th, 2012 at 6:29 pm

      Room temp is a good rule of thumb when baking.

    The dessert fairy found these on Pinterest and was kind enough to share some with me. Wow, they were great! My husband definitely didn’t get his fair share of the package. 🙂

    Has anyone used frozen blueberries?

    • Samantha replied on — January 18th, 2013 at 8:14 pm

      I don’t see why it wouldn’t work 🙂 Give it a shot!

    Rachel — January 30, 2013 at 5:33 pm

    Did you thaw the frozen blueberries first?

    • Samantha replied on — January 30th, 2013 at 7:11 pm

      I wouldn’t. I’d just throw them in as is and bake. Hope that works out for you. I think it will be okay.

    Made these today for a baby shower – everyone loved them! I used frozen blueberries (did NOT thaw prior to baking) – turned out GREAT! Definitely making them again.

    Thanks for sharing. I have found this recipe on Pinterest and made it for Easter brunch. It was soooooo good, but so high in calories! I will definitely need to find a way to cut some calories, because I want to make them again!

    I used frozen (not thaw prior baking) and fresh blueberries.

    Do you mix in whole blueberries or do you crush or puree them first?

    • Samantha Seeley replied on — April 16th, 2013 at 2:35 pm

      I mixed in whole blueberries but I’m sure you could also crush/puree them.

    About how many does this recipe make?

    • Samantha Seeley replied on — June 21st, 2013 at 11:47 am

      About 9 bars depending on how big you cut them. The recipe fills a 9×13 dish.

    Made these a couple days ago, added one teaspoon cinnamon. Absolutely wonderful! We all loved them. I did have to bake them for an extra fifteen minutes. Thanks so much for sharing.

    I made these last month and they were divine! Now that fall has arrived, have you tried the pumpkin in place of the blueberries yet? I was interested in trying it, but wanted to know how they might turn out. Thanks!

    Can salted butter be used? I don’t have any unsalted on hand. Or is there a substitute?

    • Samantha Seeley replied on — February 20th, 2015 at 4:50 pm

      Hi Sarah, Yes you can use salted butter in place of unsalted.

    Why did you change the recipe from the original that I pinned a year ago? I really enjoyed the first recipe you posted & am disappointed that I can’t find it now.
