Blackberry Crumb Bars

August 11, 2014

This is such a great recipe when summer is bringing all the delicious fruits! Now I’m a diehard chocoholic, but there’s something about fruit desserts in the summer. Blackberries are high on my favorite fruit list and they’re fantastic in these Blackberry Crumb Bars. Feel free to sub blueberries, raspberries, or maybe a mix of all your favorites! The crust is delicate and has a hint of lemon and cinnamon. Those plump blackberries are in the middle, sweetened ever so slightly. The same crust as the bottom is crumbled on top. I highly suggest serving these bars warm with a big scoop of good vanilla ice cream. I love it when you get a bite that’s warm and cold, and the ice cream gets a little melty. Summer at its best!

So, how’s it taste?

I made these bars for a coworker’s birthday, who is a big fan of fruit desserts, and they were a hit. I kept sneaking in the kitchen to get another bar and another big scoop of ice cream. Diet downfall for realz that day!

I like these bars because the crust is sweet and it helps to balance the really tart fruit. The blackberries I used were already tart, but they do get a little sugar shower. The recipe called for the juice of one lemon, which can vary greatly, and I think I had a really juicy lemon. I adjusted the recipe slightly to only call for 1/4 cup fresh lemon juice. The tart lemon took over the flavor of the blackberry, but I’m a big fan of lemon desserts so it didn’t bother me. If you really wanted to cheat and sweeten this recipe, you could use pie filling. I tend to lean toward the fresh fruits though. Use them while they’re at their peak!

    I am the same as you. I love chocolate desserts, but in the summer it is all about the summer dessert. Might as well make the most of the fruits being as good as they are at the moment.
    These look amazing. Can’t wait to try it.

    I was all, “oh, these look awesome. I love fruit desserts and these look messy than a crisp” and then I saw two sticks of butter! Another dessert I’d rather just have a piece of than to make myself so I can be in denial about all the fat and calories. 😀 But, dang, they look good.

    Ohhh! yum! I bought a ton of blackberries at the farmers market last weekend. I made a blackberry cobbler that wasn’t nearly as good as I hoped it would be. I think I need to redeem myself with these bars!
