Oatmeal Banana Peanut Butter Muffins

April 21, 2020

Extra-ripe bananas and all-natural peanut butter make these oatmeal banana peanut butter muffins a healthier snack option! Made in one bowl and no added sugar, these muffins will become a must-bake healthy treat!

This recipe came about when I opened up my freezer and found 12 overripe bananas. #truestory Since I already perfected banana bread (which is my usual go-to), I decided to change it up and experiment with one of my favorite flavor combinations: peanut butter + banana.  

Think banana bread meets oatmeal meets peanut butter. It really doesn’t get any better than this these Oatmeal Banana Peanut Butter Muffins! Once you save up enough ripe bananas, you just need pantry staples to make these delicious muffins. 

Ingredients You Need:

  • oat flour – you can easily make your own by grinding rolled oats if you don’t have oat flour on hand!
  • baking powder
  • baking soda
  • sea salt
  • VERY ripe bananas – I’m talking black, mushy bananas!
  • vanilla extract
  • egg
  • peanut butter – I like to look for an all natural version where the ingredients are just peanuts and salt.
  • unsweetened almond milk

No Sugar Added!

Did you notice that sugar isn’t on the ingredient list? The ripe bananas add enough sweetness for these banana peanut butter muffins… you just have to make sure they are super ripe. Bananas that aren’t quite ready are more tart while bananas that look like they should be thrown away are actually almost caramelized and perfect for these muffins! If you like things on the sweeter side you can add some coconut sugar.

Making and Storing These Muffins

To store these muffins: you’ll want to make sure they’re completely cool first. Allow them to cool in the muffin tin for 20 minutes before moving them to a wire rack to completely cool. Store in an airtight container at room temperature for up to three days or in the freezer for up to three months.

    Can I replace the peanut butter for almond butter? My little boy is allergic to peanuts.
