Apple Peanut Butter Baked Oatmeal

Ever since I posted a picture on Instagram a while ago of my favorite oatmeal recipe, I’ve been eating it almost every day in the mornings. It’s super quick, healthy, and what’s not to love about apples and peanut butter? It’s one of my all-time favorite food combinations, and putting it into my morning oats is absolutely amazing. I was on Pinterest the other day, and I found this snickerdoodle baked oatmeal from The Seasoned Mom. The idea of baking oatmeal and having it for breakfast in little bars is genius. I honestly can’t believe I hadn’t thought of it before… it really never occurred to me to make oatmeal in baked form until now. Thank goodness for Pinterest!

It’s no secret that I love apples, for sure. We buy our apples in bulk from Costco, and they usually come in packs of 8. However, the batch we got had about 10 small apples, so I had to find a way to use up a larger amount of them so they wouldn’t go bad. This recipe is perfect if you’ve got some extra fruit lying around, including blueberries, strawberries, or bananas. Let me know if y’all want more baked oatmeal recipes! I’d love to make more!
