These Blueberry Muffin Bars Are Next Level!

This is one of those great old-school recipes that my own mom recently uncovered when she was sorting through old recipe files. My folks are in the process of moving out of my childhood home, so there have been A LOT of old gems uncovered during this clean-out phase.

My mom has always been a PRO when it comes to preparing delicious homemade goodies that come together quickly and easily, yet taste like she spent hours in the kitchen. She’s a master at doctoring up a box of brownie mix, and she has taken the classic blueberry muffin mix to the NEXT LEVEL with these special bars!

With Mother’s Day on the horizon and fresh berries in season, I can’t think of a more appropriate way to celebrate YOUR mom than with my Mom’s recipe for Shortcut Blueberry Muffin Bars. It’s a treasured treat that my own children have come to adore! In fact, when they smell these baking, they automatically know what’s for breakfast in the morning (and for snack that day…and for dessert that night…you get the idea)!

Enjoy, my friends!

Delicious buttery and crumbly blueberry muffin bars that come together in a matter of minutes!


  • 1 16.9 ounce box organic Wild Blueberry muffin mix*
  • 1 cup oats**
  • 1/3 cup coconut palm sugar can substitute with brown sugar
  • 6 tablespoons 3/4 stick Horizon Dairy Organic Salted Butter, cut into small pieces
  • 1 9 ounce jar (about 14 tablespoons) all-fruit blueberry jam or preserves***
  • ¼ cup fresh blueberries


  • Preheat oven to 375°F (190C). Spray an 8-inch square baking dish with cooking spray and set aside.
  • Rinse blueberries in a colander and set aside to drain.
  • In a large bowl combine dry muffin mix, oats, and brown sugar. Use a pastry cutter or a fork to cut in the butter until the mixture is crumbly.
  • Set aside 1 ½ cups of the crumb mixture.
  • Press the remaining crumb mixture into the bottom of the prepared baking dish to form the crust.
  • In a small bowl, gently combine drained blueberries, additional fresh berries, and jam. Spoon over the crust and spread evenly.
  • Sprinkle the remaining crumb mixture over top and gently press down.
  • Bake for 20-25 minutes, or until golden brown.
  • Cool completely on a wire rack before cutting into bars.


  • *Any brand will work – just make sure that it includes a can of wild blueberries in the box.
  • **I use Old-Fashioned rolled oats because that’s what I keep in my pantry, but quick-cooking oats would also be fine.
  • ***If you can’t find blueberry jam, you can also substitute with blackberry jam or preserves.

  1. Wow! These bars look amazing! What great shortcuts. I’m usually scrambling to get everything ready in time for brunch. These bars would definitely take some stress off 🙂 Hope you have a great Mother’s Day!

  2. I can’t believe how ridiculously easy these are to make! They look like they take loads of work!
    Using muffin mix is genius!

    1. Hi, this treat looks amazing. I live in Ireland so I can’t buy wild blueberry mix, what could I get instead of this mix? Thank you

      1. Hi, Magda! Do you have other blueberry muffin mixes available? Those might work instead of this particular brand. 🙂

  3. You had me at shortcut muffin bars! These look amazing, Blair! I can never resist anything with blueberries, especially muffins. Sounds like this would be perfect for breakfast, dessert, a snack, and Mother’s Day!

    1. Thanks, Gayle! It’s like the best of all worlds, right? Shortcut. Muffins. Blueberries. Bars! 🙂

  4. I love this shortcut version of blueberry bars!! Sometimes you just need a quick fix recipe!!

  5. My family loves blueberry, I know these muffin bars would be a huge hit at my house! They look delicious!

  6. I stocked up on so many berries and have enjoyed them nonstop. At some point I should actually bake something with them, and this looks great!

    1. Oh, you NEED to try these, Mary! They’re perfect when you have a few extra berries to spare!

  7. 4 stars
    I am staying with some family friends over the mother’s day weekend and these look like a great way to make a treat for them without tying up their kitchen forever. This is such a great find!

  8. 5 stars
    I love these shortcut blueberry muffin bars! I would love a couple right now with my coffee 🙂 Just yum!

    1. Thanks, Oana! I wish that I had another batch in my kitchen as well. Those little things disappear FAST around here!

  9. I’m so excited to try these! I was hoping to find a blueberry dessert using my muffin mix…and this popped up! It’s exactly what I am looking for. Thanks for sharing your moms recipe!

  10. Please note that this recipe first appeared inside packages of Duncan Hines Wild Blueberry Muffin Mix in the mid-1970’s. I have been making them since then and will probably try the Seasoned Mom’s tweaks to their recipe, which were doubling the jam and adding the fresh blueberries.

    1. Good to know! That’s probably where my mom originally found the recipe — long before I was born! 🙂 I hope you enjoy this version as well!

  11. My results had too much dry ingredients but I followed the recipe exactly using quick oats.
    What did I do incorrectly?
