Two Ingredient Cookies with a text title overlay.

These Healthy Banana Oat Cookies have just 2 basic ingredients (and loads of options for a 3rd ingredient to make different flavors) and they are nutritious and totally delicious too. With these nutritious ingredients, they could be breakfast cookies! Not only will kids love eating these banana oat cookies, but they will have so much fun making them as well.

Who knew that combining oats and banana could make delicious little healthy cookies? We did! And these are too good not to share with you all.

We love a sweet snack for an afternoon pick-me-up and these totally hit the spot. They are vegan, gluten-free (if using GF oats) and nut free.

These healthy oat cookies are a great opportunity to get younger kids involved in the kitchen. They can help with mashing the bananas, stirring in the oats and then also choosing any extra ingredients that you want in the cookies. They will have fun getting messy forming the cookies and adding them to the baking tray too.

Ingredients and Substitutions

All the ingredients needed for this recipe with text overlay labels.

A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.

  • Bananas - The key to these oat banana cookies being the best that they can be is to use super soft and ripe bananas. To ripen a banana, put it in a paper bag along with a high-ethylene producing fruit such as an apple and fold the bag and let it ripen.
  • Oats - We used plain rolled oats for making banana cookies with oats. If you want these 2 ingredient cookies to be gluten free, then make sure that your oats are gluten free certified.

Banana Oat Cookie Variations

So, the basic recipe for these banana oat cookies is just 2 ingredients, but by adding a third (which we did), you can add so much more flavor and the possibilities are endless. Why have 2 when you can have 3?

Chocolate - For me, it's all about the chocolate chips. Banana and dark chocolate chips are such a good combination and you can't go wrong with a chocolate cookie. We use Refined Sugar Free Dark Chocolate Chips for these banana oat chocolate chip cookies.

Nut Butter - If you love peanut butter cookies then stir a couple of spoonfuls of peanut butter into the mix, or even some Nutella for a nutty chocolate mix.

Spice - An easy way to add a lot of flavor without extra calories to these banana cookies with oats, is to mix in a spice like cinnamon or ground ginger.

Other great additions are coconut, raisins, dried cherries/cranberries, vanilla or crushed nuts for 3 ingredient cookies. Make a few different batches with different 3rd ingredients and see which is your favorite.

How to Make Banana Oat Cookies - Step by Step

Prep: Preheat your oven to 200°C/180°C(fan)/400°F/Gas 6. Line a baking sheet with parchment paper.

  1. Step 3: Mix well and form into cookie shapes. These won't change shape and spread when cooking, so the shape you put them on the tray is the shape they will stay. Put on a lined baking sheet.
  1. Step 4: Put them into the oven for 12-15 minutes. Allow to fully cool before eating.

What are Healthy Cookies?

We all have different definitions of what a cookie is. Some love crispy cookies, and others love soft and chewy (which is what these are). These banana oat are never going to taste like your favorite sugar packed crispy cookie, but it's a nice lighter alternative for when those cookie cravings hit.

These "cookies" are so nutritious that you can totally eat them for breakfast. Breakfast cookies? What's not to love about that! It's basically just oats and banana, so it's porridge in cookie form.

Extra Tips

  • Why have 2 ingredients when you can have 3? Get creative an add in some chocolate chips, coconut or chopped nuts for different flavored cookies.
  • These healthy oat cookies don't spread when cooking, so you will need to shape them in to cookie shapes before putting them in the oven.
  • Allow to cool before eating.
  • These are a great way to get young kids involved in the kitchen. They can mash the bananas and stir in the oats.
  • You can also change these up by blending the oats to make a flour and mixing that with the banana. You could also use ground almonds instead of oats.
  • You can add some vanilla extract for extra flavor.
  • An ice cream scoop is the best thing to use to get the right amount of mixture for each cookie.
  • If adding chocolate chips, use 0.33 cup (70g). This will change the nutritional information though.

Frequently Asked Questions

Do these taste like banana?

I know not everyone is a fan of banana, but we love it when it comes to baking for giving a natural sweetness. I am not going to lie, these do taste like banana because of how much is used. So, if you or your kids aren't a fan, or someone is allergic, then this isn't a recipe for you. We haven't managed to find anything suitable to replace it with.

How to store banana and oat cookies

You can keep these cookies in an airtight container in the fridge for up to 4 days. They also freeze well. Put them on a baking tray in a single layer and then once frozen they can be put in to a freezer bag and kept there for up to 3 months.

Can you cook banana and oat cookies in the air fryer?

Yes, you can. They will take around 10 minutes at 190°C.

    Once these have been frozen, are they okay to eat once defrosted or do they need to be reheated first?

      No, you don't need to reheat them. I just add them to lunch boxes.

      They are pretty soft because of the oats. Kind of like baked porridge.
