Loved this version of baked oatmeal! You can never go wrong with peanut butter 🙂
Right?! My thoughts exactly!! So glad you loved it, Erin.
Made this this morning, and I only slightly fiddled, adding a handful of chocolate chips. Delicious and kid approved! #EBFrecipeclub
Woo!! So glad you loved this recipe, Carla. Thanks for making it and for coming back to leave a review. I so appreciate it!
This tastes really good. I might try a slightly larger dish next time because this came out really tall and didn’t quite bake through. I baked it for 35 minutes and then put it back in the warm oven for another five minutes. I also added cocoa chips. I didn’t have the flax seed. I’m curious to see if the texture changes after fully cooling.
Hey Melissa – I’m glad you enjoyed the taste of this recipe! The chocolate chips probably added a bit more liquid once melted so the baked oatmeal probably just needed some extra time to cook. Let me know how this ended up turning out for you!!
So easy to make as I typically always have all ingredients on hand. Super filling and lots of yummy flavors! Just wish my 7 year old liked it!
Super easy and delicious!
Woo!! I’m so glad it was a hit!! Thanks for the review, Michelle. I so appreciate it. 🙂
This was unreal so much taste and filling healthy treat
I have made a few of your baked oatmeals & they’re yummy BUT there are a # I can’t make (including this one) as they’re way too high in FODMAPS. (So no peaches, no apples & only minimal bananas.) Would it be possible to make this w/ only 1 banana thus lowering the fructose load that my tummy can’t handle? Also, my son is allergic to peanut butter, could this be made with another nut butter? Thanks.
Hey Julie – Yes, you can use almond butter instead of pb and as far as the banana goes, I would swap the second one with applesauce if you can have that.
I made these for the first time this afternoon and made a few minor changes because of what I had in my pantry. I used only two bananas because that’s all I had, snd used peanut butter powder mixed with water for the drizzle on the top. Saved a ton of calories! Also in place of the cinnamon I used Bakers Chai powder (available at the Savory Spice Shop on line ) and they came out delicious! I snuck a taste and can’t wait for breakfast. I made them all summer with blueberries and peaches and froze them and reheated whenever I wanted one!!
Delicious and so simple and versatile!
