We picked a lot of blackberries last year and froze them by the gallons. I freeze blackberries with the same method I use to freeze raspberries.
In addition to these bars I also make baked french toast, blackberry muffins , blackberry peach cobbler and blackberry jam with the berries.

Great recipe and very tasty. I would really making a extra 1/2 of crust .
Kathy says
Thanks so much! With the extra crust are you wanting more on the top or on the bottom? 🙂
Gail Hergert says
Delicious. Easy to make. They were not too sweet. The fresh blackberries shined. And the crust is great.
Thanks
Kathy says
Thanks so much! So glad you enjoyed them! 🙂
Beth says
Delicious, but not enough to fill a 9" x 13" pan. An 8x8 would be better.
Kathy says
Thanks for you tip! 🙂
Amy says
After reading the reviews, I realized that absolutely no none had actually MADE these pie bars. Not sure how you can review something you haven't baked or eaten but....oh, well. So I thought I would try these.
*Caveat: I'm not a huge fan of blackberries but have them growing wild all over my farm. Rather than see them go to waste, I decided to try some deserts. So please take into consideration that I'm not a huge blackberry fan when looking at my rating. Despite all that, these pie bars are quite tasty.
The recipe is quick and easy - I have a food processer but didn't see the need to use it for this recipe and it still ended up looking and tasting great. I did not change a thing - no additions or subtractions - and my family really enjoyed them. I did not de-seed the berries (I don't think the recipe calls for it anyway - or else I missed it) so they were quite seedy. That is the only thing I might change when making the recipe again.
The taste isn't overpowering; just a subtle hint of sweetness, and the crust and topping weren't cloyingly sweet, either (I do like very sweet desserts but this one was not too sweet and not too bland). A nice way to utilize those blackberries and get your sweet tooth fix for the day!
Kathy says
Hi Amy,
Thank you for your comment. Good for you for trying these, even though you don't care for blackberries. I'm glad you found them quite tasty.
Thank you,
Kathy 🙂

Kathy, these blackberry pie bars look just wonderful! Love those big juicy blackberries. So easy using the same mix for the topping and the crust.
Kathy says
Thanks, Kelly! These are super easy to make and the blackberries add so much flavor!
Matt @ Total Feasts says
Oh, I love love love blackberries! What a great idea, the only time I've actually baked with blackberries is if I'm making a crumble. These bars sound delightful, and a perfect tea time dessert!
Kathy says
Thanks, Matt!
Nicoletta says
Wow, I was almost missing these beauties! Pie bars, with delicious blackberries nestled inside!! That is one wonderful dessert, Kathy!
Mary Ann | The Beach House Kitchen says
These look totally delicious Kathy! Fruit bars are a regular during the summer here at the beach. I will definitely be adding these to my baking list!
David @ Spiced says
I absolutely love blackberries! I keep hoping I'll stumble on a wild patch of blackberries somewhere around here, but it hasn't happened yet. We had a great blackberry patch in the old house, so I need to start a new one here. In the meantime, I'll have to rely on storebought berries. These pie bars sound (and look) incredibly tasty, Kathy! Perfect summer dessert!
Kathy says
Store bought berries are delicious too. 🙂
Valentina says
A pie, a bar, a cookie -- I'll take this in any shape or form. Love that it works with frozen berries, too. That way the deliciousness lasts all year long. 🙂
Kathy says
I just need to make certain I stock my freezer with blackberries again this summer so I can enjoy these all year long!
Cheryl says
Yum! Looks great. There are tons of blackberries growing all over the pasture. I discovered some new brambles when riding my horse around the field a couple of days ago. Ouch! I think I'm going to get back into picking and freezing blackberries again. I tend to bake blackberry pie with the ones I pick, but I'm always looking for different recipes to try - thanks!
Kathy says
I think it's time to get picking again - and baking!
Haylie / Our Balanced Bowl says
Kathy, this looks so Summery and delicious! I'm all about anything pie - especially when it's handheld like this! Perfect to pair with my coffee!
Kathy says
It's a delicious summertime dessert!
Fred G says
What a great idea.
Kathy says
