Blueberry Jam Bars

Blueberry Jam Bars combine your favorite jam with a buttery, nutty, oat crust. - Bake or Break

My first baking love will probably always be chocolate. I’m sure I am not alone in that sentiment. However, I do try to vary things a bit around the BoB kitchen. These bars are a nice deviation from the norm.

I’m pretty much a fool for the crust and crumb of these bars. Butter, oats, brown sugar, cinnamon, and pecans…. Yes, please! There’s just something so warm and comforting about that combination. It’s certainly hard to resist.

Blueberry Jam Bars combine your favorite jam with a buttery, nutty, oat crust.

In between those delicious layers is a thin layer of preserves. I let Quinn choose the flavor, and he picked blueberry. I must say that I think he chose wisely. The combination of blueberry preserves with the crust/crumb is just right.

If you’re an ice cream fan, these would probably be quite lovely with a little dollop of vanilla right on top. I’ll go the purist route and take them as they are.

  1. I’ve always been a fan of bars, yours look chewy and that’s how I like them

  2. Uh huh…I knew you would have to venture to “not chocolate” land just to balance the entries. But I was just wondering if you could replace the preserves with Nutella…just saying. Or if you did orange marmalade you could serve them with a drizzle of Nutella…I love orange and chocolate…still just saying!!!

  3. Tim, Nutella sounds brilliant to me. Brilliant.

  4. These look wonderful. I’m partial to blueberry too.

  5. I would love to put brownie batter layer in between – since I am a little over partial to chocolate 🙂
    I’ve tried it before with other chewy bars and your recipe looks tops!

  6. Yummy! What brand of jam did you use? I can never find any that taste ‘right.’ :/

  7. I love making my own cereal bars… at least that way I know what’s in them.
    These look delicious.

  8. Wow, these look so delicious!!

  9. My husband is wild about blueberries…I can’t wait to make these for him!

  10. Looking forward to trying these. What is the best way to store? Fridge or room temp?

  11. Just cut the cooled bars. So so so yum! Thanks!

  12. This recipe just popped up on my FB page and since I made peach jam last week, I think I will make this but use my jam. I think it will be really yummy!

  13. Just made these, they are sooooooo good.

  14. Omg. I didn’t read the directions thoroughly. I skipped a step.

    After pressing half of the batter on the bottom of the cooking pan, I immediately added the blueberry jam, then sprinkled the rest of the batter on top. It is now baking in the oven.

    I am now jittery waiting for the outcome of my erratic baking .

    Hoping against hope the recipe is forgiving — that somehow it turns out still more or less okay, maybe with more time in the oven.
