IS IT SPRING YET?!?!!? For real. I am getting so stinking stir crazy. And a little bored. I’m meeting new friends though. Today at the library, I saw a mom that I saw at the mall play area just last week (I was just there yesterday too, for the record). We’re allllll going stir crazy and I’m getting so tired of the same ol’ routine:

Monday: Play area at the mall.

Tuesday: Library.

Wednesday: Play date at friends or other fun indoor location (yes, we have taken our children rollerskating. Yes, it is hysterical. Yes, E loves/hates it.)

Thursday: Shopping or errands.

Friday: Open gymnastics or other INDOOR activity.

Sounds fun right? No really, it actually does sound fun. And it is fun. Was fun. The first 4 weeks of winter or so. Now? I’m craving summmmmmer. Parks. Zoos. Splash pads. Even just a walk around the stinkin’ block. C’mon Michigan!!! Throw us a bone.

I’m sure you’ll all be happy when it finally gets warmer too because then maybe I’ll finally stop complaining about it.

In the meantime, I’ll bake. And I’ll throw berries in and pretend they are not from Mexico.

These bars are so good — the chewy oats give them great texture and the filling! Oh I could eat the filling with a spoon. Tons of crumb bar recipes use jam or jelly as a filling but I quick threw one together myself with fresh blackberries and frozen blueberries (fresh would be great too…but…umm…yeah.). These crumb bars are also flavored with plenty of lemon and lemon zest to freshen the whole thing up and then a little secret ingredient — cardamom! Adds an amazing subtle flavor that takes these over the top. Enjoy!

Blackberry and Blueberry Crumb Bars

Yield: 15-20 bars depending on size of bars

Prep Time: 20 minutes

Cook Time: 49 minutes

Total Time: 1 hour, 9 minutes

These blackberry and blueberry crumb bars are easy to make and so full of flavor thanks to a layer of blackberries and blueberries.

Ingredients:

For the filling:

  • 1/4 cup sugar
  • 2 tablespoons cornstarch
  • 1 cup blueberries
  • 1 cup blackberries
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon lemon zest
  • 3 tablespoons water

For the bars:

  • 2 cups oats (quick or old-fashioned -- I used a mix of both)
  • 2 cups all-purpose flour
  • 1 and 1/4 cups light brown sugar, firmly packed
  • 1/2 teaspoon ground cardamom
  • 1 teaspoon lemon zest
  • 1/2 teaspoon salt
  • 2 tablespoons fresh lemon juice
  • 1 cup unsalted butter, cold and cut into small pieces

Directions:

  1. Preheat oven to 325 degrees Fahrenheit.
  2. In a small saucepan, mix together sugar and cornstarch. Add remaining filling ingredients (1 cup blueberries, 1 cup blackberries, 2 tablespoons lemon juice, 1 teaspoon lemon zest and 3 tablespoons water). Stir to combine. Bring to a simmer over medium heat and stir frequently. Reduce heat to medium low and continue to cook until thickened and berries are mostly broken down (10-15 minutes).
  3. Meanwhile, prepare dough for the bars. In a large mixing bowl, combine oats, flour, brown sugar, cardamom, 1 teaspoon lemon zest, and salt until well combined. Sprinkle mixture with 2 tablespoons fresh lemon juice. Add butter and use a pastry cutter or two forks or knives to cut in the butter pieces until the mixture is crumbly and there are no large chunks of butter remaining.
  4. Spray a 9x13-inch pan with nonstick cooking spray.
  5. Set aside 2 cups of crumb mixture. Pour the rest into the prepared pan and press down with fingers to form a uniform crust. Bake for 10 minutes or until set. Spread fruit filling evenly over crust. Sprinkle with reserved oat mixture and press down gently (be careful for the hot pan!).
  6. Bake for an additional 35-40 minutes or until golden brown.
  7. Cool completely before cutting into bars.

Note: Lemon juice and zest needed for this recipe requires about 3 large lemons.

Verdict: Oh my goodness. I may have had one (or two) for breakfast.
Husband’s take: He liked them too — and I made him take them to work so I wouldn’t eat them all. Word is that people at his work are getting mad at me for sending them all my sweets. Anyone want to be my taste tester?
Changes I would make: None are necessary.
Difficulty: Easy.

  1. Your little guy in the cupboard is SO FREAKING CUTE! I die.
    These crumb bars look delicious! My hubby LOVES blackberries and I love oatmeal…perfect marriage! Pinned

  2. I understand how the same routine gets old. We can’t even go outside because of all the dirt and wind blowing around here.

  3. I hear you! We can’t wait for warm weather, but here in New Mexico spring means WIND. Like bad wind, so bad that you can’t go outside, so we all kind of hope for summer but then it’s too damn hot. Ugh. Never happy lol. But I’d be totally happy with a few of these little bars!

  4. This recipe sounds so delicious that I plan to make a batch as soon as possible! However, the main reason that I chose to comment was that I wanted to mention that the photograph of the smiling baby in the cabinet is precious. Even the plastic carrot top in the bottom right-hand corner in front of the cabinet adds interest to this remarkable photograph. First, this photo reminds me that despite what some parents may believe that they need to purchase expensive toys for their children, this one says otherwise. Sometimes a wooden spoon, some pots and pans, reusable containers, and an empty cabinet are all that some children need to entertain themselves, which this photograph proves this point. Second, the smile on this baby’s face is contagious. This baby’s ingenuous joy and pleasure at sitting in this cabinet lifted my spirits. After observing this baby, I thought to myself, “This is going to be a great day!” Thank you for sharing this noteworthy photograph with others and with me.

  5. Oh I hope it gets a bit warmer for you soon! It can’t be fun at all being stuck inside with two small children all the time. On the other hand, it does mean that we get delicious looking treats like this!

  6. Okay these look SO good. I’m picturing a pan of these, coffee, and time with girlfriends. YUM!!! PS ~ I have to say I am SO with you…. COME ON SUNSHINE AND WARM WEATHER!!!

  7. Summer will be here soon. I want those bars for breakfast!!!

  8. yum–I love blackberries! One of my favorite memories is picking them on my grandparents’ farm in Tennessee, then coming back to the house and eating them with sugar and cream. When I was really young, the cream was made from raw milk because they had their own cow.

  9. Oh, I am so with you. I cannot wait to bust outta my house and be outside for longer than two seconds without freezing my tail off. Until then, I’ll just be eating these yummy bars all day every day. 😉

  10. Move your cute little butt to California where the sun is shining yearround and I am dying to have a playdate with you! We can hit up the zoo, go to the lake, run around like wild animals in the park … your choice! 🙂 but um, before you load everyone up on the plane, make sure you stash a good batch of these bars, okay? I LOVE blueberries and the crumb is on point!

  11. I think I still have a bag of frozen berries from last summer in the freezer. Making. These. STAT!

  12. I love blackberries! Such a great way to get rid of all the blackberries out of my freezer! Can’t wait to try this!

  13. These bars look awesome! I have found some blueberries from the US and I may have done a happy dance in the middle of the grocery store 🙂 I live in MI too, and I can’t take this winter anymore. I’ve barely left the house.

  14. I love bar cookies, because you do it in one batch and it’s over. Also because I never met a bar cookie I didn’t like. I have met some brownies I didn’t like because I often find brownies dry. I am never sure if it’s people’s recipes or they over bake them. This is a little different combo with the filling. I never met a berry I didn’t like either. I think we have a Bingo here.

  15. Haha, look at that sneaky little guy in your cupboard – too cute! These bars are beautiful, Rachel! There’s no better spring/summer dessert than a crumb bar using fresh berries, and these are a knockout!

  16. Ooo, pick me, pick me! I want to be your taste tester!! I’m dying over these. Actually, more accurately, my stomach is growling over them. Literally.

  17. These bars look amazing! I just pinned them 🙂 It’s hard when the kids are young and you feel trapped inside. I feel trapped, but at least mine go to school. Spring is coming and we can all feel normal again! I can’t wait to make these bars!

  18. I’m ready for a sunny spring, too. I went for a walk in the pouring rain just to dust off the cobwebs and stretch my legs. Then came back freezing cold. I need sunshine! And one of these gorgeous bars. Duh!

  19. I cannot wait for spring weather! But until it warms up, I guess I will just have to eat these bars and pretend that it’s warm and sunny!

  20. These bars sound perfect! So Springy! Im ready too 🙂
    By the way, you’re kids are so lucky you do all those things with them! Want to know how many times we’ve left the house since Monday…once. yah. And it’s not even crappy weather here! You’re my superhero.

    • I’d go crazy if I didn’t. I can only stay in the house one day a week. I’m lucky to have a group of 4 friends who live nearby with similar aged kids — so there’s always at least one other mom there with me…so it’s fun for me too. Exhausting, but fun. 🙂

  22. I’m so ready for spring too!!! These crumb bars sound awesome, and look amazing too!

  23. I love any kind of sticky berry bar with a crumble top. These look divine Rachel! We’re heading into autumn over here, the nights are gradually cooling down but the days are still sunny. Hope that you get some warmer weather soon… enjoy the onset of spring/summer fruits, veggies and sunny days! x

  25. Hi I want to make these for a wedding. I have to make them a few days ahead because the wedding is 5 hours away. I was wondering will the bottom get soggy if they are made that far in advance?
