creamy peanut butter is combined with juicy peaches for a summertime baked oatmeal dish that’s perfect for breakfast or snack. kid & adult-friendly, it’s an easy way to feed yourself, or a whole family all week long!



  • 2 cups old fashioned or rolled oatmeal
  • 12 teaspoons ground cinnamon (depending on how much you like)
  • 1 teaspoon baking powder
  • 2 tablespoons chia seeds
  • 12 tablespoons brown sugar, packed (depending on how sweet you want it)
  • 1 large egg
  • 2 cups milk of choice (see note #1)
  • 1 1/2 teaspoons vanilla
  • 1/3 cup natural creamy salted peanut butter
  • 1 cup (about 2 small or 1 large) ripe peaches, washed, pitted and cubed (I kept the skin on, you can peel them if you want)
  • Optional toppings: additional peanut butter, yogurt, pure maple syrup, diced peach


  • Preheat oven to 375*F
  • Grease a 8×8 baking dish (you can use smaller or larger but cooking times will vary. For a smaller pan, you will have to bake longer to ensure it’s fully cooked in the center).
  • In a large mixing bowl, combine egg, milk, brown sugar, peanut butter and vanilla.
  • In a separate mixing bowl, combine oats, baking powder, cinnamon, chia seeds and salt (if using, see note #2)
  • Add dry to wet mixture, folding gently to combine, then fold in peaches. Let sit for 2 minutes to allow chia seeds to soak up some of the moisture
  • Pour into greased baking dish using a spatula to spread the mixture evenly throughout the dish
  • Bake for 30-40 minutes until golden brown (because every oven is different, I recommend plunging a knife or cake tester into the center of the dish to test if it’s done, if it comes out clean or just a bit wet, it’s done).
  • Allow to cool completely before slicing (you don’t HAVE to wait, but note that the squares may fall apart a bit if you’re scooping it out of the dish right when it comes from the oven).


  1. If your peaches are very juicy, you may want to decrease the amount of milk or increase the amount of chia seeds you add (giving them 2 or so minutes to soak up some of the liquid before baking) to avoid a soggier texture.
  2. If you use unsalted peanut butter, add 1/4 teaspoon salt to the dry ingredients 
  3. Oats keep well in an airtight container in the fridge for up to 5 days.  Reheat in the microwave before serving or serve cold.
