Ingredients to make Oat Cookies
- Ripe bananas – the riper the banana the better!
- Peanut butter – the hero ingredient! I love the texture that crunchy peanut butter offers to these peanut butter oatmeal cookies, however smooth peanut butter would also work.
- Oats – I have opted for gluten-free oats, however, standard rolled oats, old-fashioned oats, instant oats or quick oats would also work perfectly well in these 3 Ingredient Oat Cookies.

Substitutions
- Bananas – If you don’t like bananas or have an allergy to them, you could try substituting them for apple sauce instead.
- Peanut butter – If you have an allergy to peanuts or don’t have any in the cupboard you could substitute this for other nut butters such as almond butter.
- Oats – Oats in this recipe could be substituted for buckwheat flakes.
Variations
- Kid-friendly – If you have kids these chewy Cookies are the perfect baking recipe for them to make either on their own or with your guidance. Add in chocolate chips or chocolate chunks to make them into healthy chocolate chip cookies.
- Deluxe – You could easily add extra ingredients to make these the best oatmeal cookies. Seeds, vanilla extract, orange zest, sea salt, hemp seeds or raisins would make them into delicious oatmeal raisin cookies that everyone will love.
How to make Oat Cookies
Step 1: Firstly, preheat the oven to 180C (360F). Then peel and mash the ripe bananas in a large bowl.
Step 2: Now add in the oats and peanut butter to the mixing bowl.
Step 3: Mix together the oat mixture until it’s sticky and well combined.
Step 4: Finally roll into 6 ball shapes (or use a cookie scoop) and place them onto a baking sheet line with parchment paper. Press the balls down with a fork into round cookie shapes. Place into the oven at 180C (360F) for 20 minutes until golden brown but still having soft centers. Allow to cool (on a wire rack if you have one) at room temperature for 10 minutes before tucking in!
Leftovers
Allow these banana Oat Cookies to cool and store in an airtight container at room temperature for up to 3 days. You can also freeze these to have on another day. Defrost naturally or microwave to defrost for on the go.

Notes
Nutrition
Super quick and easy to make. I added some sultanas, sunflower and pumpkin seeds and a dash of vanilla essence to mine. Very happy with them!
Thank you Mary-Anne 🙂
Is the nutrition per biscuit or batch please
Hey Claire, yes always per biscuit or portion 🙂 enjoy
Great recipe Very moreish. I added grated carrot for sweetness
Thank you Johanna 🙂
Hi! Can you also bake these in the airfryer? 🙂
Hey Lea, good question! I haven’t personally tested them in air fryer but I think it will work fine. Aim for 10-12 mins at 180c. Let me know how it goes 🙂
Hi
Any idea why mine came out really soft and chewy- the mixture was really sticky and very very soft. Cooked them at the right temp and time too
Hey Carole, did you follow the last instruction about leaving them to cool? They helps to firm them up 🙂
I just made another batch. One of many, many batches. Great way to use up bananas. We always either have a ton left over or none (and the kids complain that we haven’t bought enough..)
Hi James, could I use the powdered peanut butter instead? Any adjustment or measurement to the recipe? Thank you.
Good question! It’s not a product I have ever used so unsure how this would effect things.
Yes, Just what I’m looking for, I didn’t have bananas used some peaches off my Son’s tree, cooked them and mashed them, tossed in a few walnuts and a tbl sp of desiccated coconut!
(Ha! Ha! Sprinkled with icing sugar to make a bit more acceptable to Mother!)
Next time I will allow them to cool longer before we eat them all!
Amazing simple and utterly delicious biscuits, we love them.
Thanks so much 🙂
I just discovered your page today and made these. I added chocolate chips, chopped pecans, a dash of salt, and penzeys cake seasoning (cinnamon, clove, cardamom). They are amazing and so easy! I ate several for lunch today, oops. I bet coconut shavings would be good in these. Tonight I am excited to try your tomato, spinach and chickpea curry. Happy to have found you!
