Have you ever seen those movie scenes where someone is baking something so delicious that the smell alone brings the whole family running to the kitchen? Well, they may very well have been whipping up a batch of Banana Oatmeal Cookies. I’m guessing based on experience since that is exactly what happens in my house!

These mesmerizing cookies are made with rolled oats, bananas, peanut butter, and chocolate chips. Seriously, that’s it. No flour, no eggs, no baking powder. No stress! Just a few delicious ingredients and you’re basking in cookie heaven.

From start to finish, these incredible cookies take about 20 minutes to make. They are soft, decadent, and downright delicious. You know, if you’re into that sort of thing. For a guilt-free indulgence, it doesn’t get much better than this.

Banana Oatmeal Cookies have been my go-to recipe for everything from birthday parties and neighborhood potlucks to quick breakfasts and dreamy snacks. I love them, my husband loves them, and my girls can’t seem to get enough of them.

Best of all? Because they do so well in the freezer, they make the perfect healthy meal prep recipe. I like to double up on the recipe so I can stow some away in the freezer as a secret weapon. When you’ve got chocolate-loving kids at home, keeping some homemade cookies on retainer is always a good idea.

From baked oatmeal to oatmeal smoothies, I am a big fan of oatmeal in the morning. If you’re looking for a way to spice up this staple ingredient, look no further. These healthy cookies are guaranteed to be a hit in your home.

Key Ingredients for Banana Oatmeal Cookies

To make this delicious healthy breakfast, you will need the following key ingredients:

  • Rolled oats: Also referred to as old fashioned oats, rolled oats are the ideal oats to use in this recipe. They are naturally gluten-free and bake wonderfully into the perfect cookies!
  • Bananas: When it comes to using bananas in baking, you always want to use the ripest ones you can find. These will develop the sweetest flavor when baked, making the cookies as delicious as possible.
  • Peanut butter: This is my personal preference, but you can also use almond butter if you prefer that instead.
  • Chocolate chips" You can use any kind you like! Bittersweet, semi-sweet, dark chocolate, and milk chocolate chips would all work great.

Recipe Variations

In the mood to get creative? Here are some of my favorite ways to switch up this dish:

  • Add a little spice. For some added flavor, try adding a pinch of cinnamon or nutmeg to your cookies.
  • Add some nuts. This is a great way to add extra flavor and heart-healthy fats. Some of my top picks include walnuts, pecans, and almonds.
  • Make them dairy-free. You can easily make this recipe dairy-free and vegan by using dairy-free chocolate chips.
  • Swap out the nut butter. If you aren’t a big peanut butter fan or you don’t have any at home, don’t worry. You can swap it out for another nut butter like almond butter or even sunflower seed butter for a nut-free version.
  • Add some seeds. For tons of added nutrients and a nutty flavor, try adding some seeds to your cookies. Great options include chia seeds, hemp seeds, pumpkin seeds, and flax seeds.
  • Make them extra chocolatey. If you’re a chocoholic looking to double up on the chocolate flavor, try adding some cocoa powder to the cookies.

How to Store Banana Oatmeal Cookies

This is one of those recipes where I always recommend making extra. You’ll thank me later! These oatmeal cookies store incredibly well both in the fridge and in the freezer. Make sure to allow them to cool down to room temperature, then transfer the cookies to an airtight storage bag or container. Once properly packed, you can store oatmeal cookies in one of two ways:

  • In the fridge for up to 1 week.
  • In the freezer for up to 3 months.
