Between starting my Etsy shop, working on client work, and applying to full time jobs, my days have been pretty hectic lately. I’ve definitely been feeling stressed. Knowing I have a healthy, homemade breakfast already waiting in the fridge for me though, makes my day that much more manageable. Everyone has crazy lives with kids, work, school, etc., but at least with meal prep breakfast can be easy.

This baked oatmeal is also the perfect way to start the day. Not only does it feature the dynamic duo of peanut butter and banana, but it’ll also fuel you for whatever your day has in store. The carbs from the banana and oats combined with the protein from the peanut butter and peanut flour makes this a great pre or post workout meal (even if your workout is trying to buckle a toddler into a car seat.). You can enjoy it hot, cold, and on the go. My favorite way to eat it is hot out of the oven with a splash of homemade nut milk and sprinkled with crushed peanuts or chocolate chips.

Make this baked oatmeal on Sunday, slice it, and enjoy it all week long. You can also freeze it, meaning you’ll never be without a healthy way to start your day.
