Pro Tips for Making Perfect Peanut Butter Banana Baked Oatmeal:

Ingredient Substitutions 

  • This recipe also works with peanut butter powder. If you go with powdered peanut butter, use 1 cup powdered peanut butter and increase the almond milk to 2 cups.
  • Make sure to use certified gluten-free oats if you or a family member has celiac or gluten intolerance.
  • Feel free to add any extras, such as chopped peanuts or walnuts for crunch, or chocolate chips. Stir them in with the rest of the dry ingredients.

    Loved this recipe. Used almond butter because I couldn’t find any organic raw peanut butter. My dish was 8 inch square shape. It came out amazing 😍

    Have you tried this with any egg substitutes at all? Applesauce, flax/chia eggs, etc?

      Hi Jill,
      I haven't tried it myself, but I don't see why a flax or chia egg wouldn't work!
