Blueberry Crumb Bars

Blueberry Crumb Bars by @browneyedbaker :: www.browneyedbaker.com

Ahh, sweet blueberries. I am positively obsessed with them right now. I’ve been eating them by the handful… and with cottage cheese… and in a bowl of cinnamon shredded wheat… and in every baked good I can possibly imagine. I can’t imagine a day when I’ll ever tire of baking with blueberries. This past weekend, I decided to combine blueberries with one of my favorite desserts – crumb bars! Give me anything with a crumb topping and I’ll devour it faster than you can say “butter”. Quite a few years ago, I made peach crumb bars, which I successfully turned into blueberry crumb bars. If you can go wrong with fresh fruit and a buttery crumb crust and topping, I haven’t found a way.

I’m sure you could easily adapt these bars to use up whatever type of berry you have in your fridge, but I am definitely partial to the blueberry. It’s my favorite of the berry family, plus I just love that beautiful purple color that baked blueberries exude.

Prepare yourself for the fact that you will continue to cut “just a little piece” until half of the pan is gone. It’s unavoidable; just don’t say I didn’t warn you!

Blueberry Crumb Bars

Yield: 20 to 24 bars

Prep Time: 20 minutes

Cook Time: 50 minutes

Total Time: 1 hour 10 minutes

Crumb bars loaded in the middle with fresh blueberries.

Ingredients:

For the Crumb:
3 cups all-purpose flour
1 cup granulated sugar
1 teaspoon baking powder
¼ teaspoon salt
1 cup cold unsalted butter, cut into small cubes
1 egg

For the Blueberry Filling:
4 cups fresh blueberries
½ cup granulated sugar
4 teaspoons cornstarch
Juice of one lemon

Directions:

1. Preheat oven to 375 degrees F. Lightly grease a 9x13-inch baking pan.

2. Make the Crumb: In a medium bowl, whisk together the flour, sugar, baking powder and salt. Use a fork or pastry cutter to blend in the butter, and then the egg (the dough will be crumbly). Press half of dough into the prepared pan.

3. In a separate large bowl, whisk together the sugar, cornstarch and lemon juice. Gently fold in the blueberries to coat evenly with the sugar mixture. Spread the blueberry mixture evenly over the crust, drizzling any excess juice in the bowl over the filling. Crumble the remaining dough evenly over the blueberry layer.

4. Bake for 45 to 50 minutes, or until the top is light golden brown. Cool completely before cutting into squares. Leftovers can be stored in an airtight container or wrapped in plastic wrap at room temperature or in the refrigerator.

    These bars look so good! I’m loving blueberries like mad right now too, and can’t wait to use a big bunch I got at the farmers market in something baked. It’s just hard to save them as I love them in everything, too!

    Beautiful Blueberry Crumb Bars, Michelle! Once again, we are on the same wavelength this week. Just made crumble bars with my mom’s tart cherry pie filling to share on the blog. I am quite familiar with the AllRecipes.com recipe, but never saw Deb’s recipe at Smitten Kitchen. I adore crumble and streusel anything, too! Thanks for sharing!

    I’m in love with bb’s too lately! My post that’s going live in an hour is with bb’s and I had a vegan bb muffin post last week, the week before that a bb cake, next week I have another bb cake. I try to space them out :) Your crumb bars are right up my alley! And I saw your Miss Mud Brownies front and center, 3rd row today, on FG :)

    I am on board, bb everything. I was wondering if you can use frozen bb’s? I was lucky enough to be given several pounds of wild frozen bb’s. :-D thanks for all your wonderful recipes.

      Hi Vic, I think using frozen blueberries would be fine; be sure to thaw them first and pat them dry.

    What is the recipe for the crust of the blueberry crumb bars?

    Reply

    • Jaime on July 23rd, 2013 at 9:59 am

      In the directions, it says to use half of the crumb topping for the crust.

      Reply

    • Michelle on July 23rd, 2013 at 1:48 pm

      The crust and topping are the same; you use half for the crust and half for the topping.

    Crumb Bars are one of favorite go-tos! So easy to adapt and works in any season with tons of fruit. Plus, I can reason that they’re “healthy” cuz they have fruit……

    These look like the perfect answer to ‘blueberries are on sale this week’! I was surprised to learn a few years ago that just a smidge of cinnamon in the crust/crumb of something blueberry is delicious.

    I have an excess of blueberries right now, and (as usual) a mean sweet tooth, so these are definitely going to have to happen soon. I love anything with berries in the summer!

    I love blueberry crumb bars, they are my weakness. And I totally slice a quarter slice, which turns into a half, which turns into a whole, which turns into the entire pan! :) Usually during the night, hey.. it happens!

    I too am obsessed with blueberries. Bought tons of them and froze a lot so I’d have them on hand. This crumb bar recipe looks just scrumptious! It’s already printed and sitting on the kitchen counter saying “make me”!

    I ran out to Sam’s, bought the berries. Found out I had used my last lemon, ran to the store again! So glad I persevered. These blueberry bars made me weak! So good! (And I didn’t run-run, I drove. Lol.)

    Blueberries are my all time favorite. Growing up as a kid in Maine we used to rake wild blueberries so we could freeze and eat them all year round. I don’t think my mother ever made these bars but this recipe speaks to me. :)

    I eat blueberries every day – in smoothies, on yogurt, with other fruit – so baking with blueberries is a no-brainer for me. Of course, I had to make this last night and brought half into my office for my co-workers. It’s only 9:20 and the plate is almost empty. They are delicious!

    Great recipe! I made these bars yesterday, and they are delicious! So yummy, in fact, that I held off on bringing them to work to share. Oops! I substituted maple syrup for half of the sugar and will probably go with all syrup next time because I love that flavour combo so much. High five for super treat!

    I am wondering about making them with frozen alaskan blueberries, they are so tart and sweet, but don’t want to waste the berries if recipe doesn’t turn out right, a lot of hard labor went into picking them.

    • Michelle on September 26th, 2013 at 4:38 pm

      Hi Viv, I’m not sure how frozen blueberries would do, but if they something you covet, I probably would not experiment, just in case.
