I would NOT be lying if I said that these Peanut Butter and Jelly Oat Bars have been my MAIN SOURCE of sustenance over the last couple days… In other words, I’ve been testing and tweaking this recipe all week and CAN’T STOP eating them!

They are peanut butter and jelly perfection, and I’m so happy that the recipe is all worked out and ready to share with you. It’s so easy, and I know you all are going to LOVE it! We’ve got a soft, peanut butter cookie base, a layer of your favorite fruit spread or preserves, and then more crumbled peanut butter cookie dough, and then a final dusting of powdered sugar!

I’ve been eating these for breakfast, lunch, dinner and everything in between, and I’m happy to say that not only are they absolutely delicious, but they do have some redeeming nutritional qualities as well… I kept the sugar content down, and used white whole wheat flour, and there’s a healthy scoop of oats. Plus, peanut butter is a source of protein, right? So, while they do lean toward the dessert category, they aren’t too naughty of a choice – at least in my book.

I used a crunchy peanut butter for added texture, and my new favorite Crofter’s Berry Harvest Organic Spread, which I found at Costco and will be stocking up on next time I go! What’s your favorite PB and J combo?

These look so good!
Thank you Izzy!
Will be making these tonight. Hubby has been told to watch his sugar intake, and we have not been eating any sweets. I miss it, and this looks like something that would be OK. I also like that, although you used berry, you could use any fruit flavor. Thanks for sharing.
I hope these are the perfect thing, and that you both enjoy them very much. Yes, you could definitely use any fruit flavor that you have on hand.
Gotta love that classic combo. Gorgeous photos!! 🙂

Thank you so much!
I love the looks of this recipe and the fact it has a minimum of sugar, so to speak. I mean, it IS a treat, after all, but not overly sweet, I don’t think. I’m enjoying your recipes. Thanks so much for sharing.
Thank you Kathie, I’m so glad you are enjoying my recipes!
Just made this morning. Crust turned out quite dry an crumbly but still tasted good. Somewhat disappointed though.
Thank you for the feedback Carol.
Could you sub almond or coconut flour for the whole wheat?
Do you put them in the fridge once cooled down ? Or leave them out
I like to leave them out, but they are fine either way. Enjoy!
