3 Ingredient Cookie Oat Biscuits Recipe

raisin banana oat biscuits

These raisin banana oat biscuit cookies are simple to make, contain no flour, no eggs, are sweetened with just bananas, take a few mins to make and most importantly taste delicious. They will curb pangs for something sweet to snack on.

If you want a healthy breakfast full of good stuff and low in sugar try this healthy treat recipe. As whole fruit is used it contains sugar but as it’s not refined it retains all the fibre and is absorbed slowly into the bloodstream.

I often have these breakfast cookies on the go thinking they are something indulgent but actually they are one of the healthiest breakfasts you could have. Some other healthy cookie recipes call for instant oats, but I’ve found out there is no need to buy expensive processed oats, simply blend normal rolled oats for a few seconds in any blender.

If your avoiding gluten just make these cookies with gluten-free oats. They do work better with the cheaper oats that are soft and crumbly.

This healthy cookies recipe is no added sugar as it just contains natural healthy sugars from whole fruit. The cookies are low calorie due to having no refined sugar or butter and are very filling. Some call them super healthy cookies that are perfect for fussy children others call them heart healthy cookies.

If you’re not a fan of raisins you can replace them with other dried fruit such as cranberries, dates, apricots and prunes – just make sure to chop the fruit into small raisin sized chunks.

These 3-ingredient cookies can be made with oatmeal and avoid using a blender to grind up oats. Always choose an oatmeal that is pure as so many brands have added sugar and flavourings. You really don’t need any flavourings in these cookies with the raisins and bananas.

To make a chocolate version of this healthy cookie just replace the raisins with your favourite chocolate chips. I like an 80% dark chocolate chip banana oat biscuit.

Apple and cinnamon biscuits are great -chop the apple into raisin-sized chunks and add 1 tsp of cinnamon. With fresh apple they do take 5 mins extra to cook and make a chewier biscuit.

Oats are quite high in plant protein but for a higher protein cookie or biscuit check out my healthy quinoa chocolate cookies.  That quinoa cookie is made with whole sprouted quinoa and sweetened with banana.

Oats are naturally gluten-free but are often contaminated with gluten either when growing or processing. They contain a protein that is structurally similar to gluten but is different and known as avenin or more simply oat gluten.

Yield: 12 biscuit cookies

3 Ingredient Healthy Cookies

raisin banana oat biscuits recipe

Easy to make healthy cookies that are sweetened with just bananas and vine fruit. These cookies make a great breakfast or after school snack and great for fussy children as they often don't realise how nutritious these are.

Prep Time 5 minutes
Cook Time 15 minutes
Total Time 20 minutes


  • 3 bananas
  • 1½ cups / 150g rolled oats
  • 2 tbsp raisins


  1. Grind the oats for a few seconds to make an oat powder. It doesn’t have to be fine, they just need to be broken up a bit.
  1. Peel the bananas and then mash them.
  2. Mix everything together until combined.
  3. Spoon onto a non stick sheet and spread out to make a cookie biscuit shape. The mixture makes 12 normal sized cookies or 6 large.
  4. Bake for 15-20 mins until golden at 350°F / 180 °C.
  5. If you want a chewier biscuit take out of the oven as they start to get some colour. For a crunchier biscuit leave until they are golden brown.
  6. As they have fresh banana they will go off quickly so it’s best to eat straight away. They can be stored for a few days in the fridge but the cookies will lose their crunch.

  1. Hi! do you think that amaranth flour could work on these? I have tons at home and this would be a way to use it! thank you so much for all your effort and recipes!

    1. Bastian Durward

      Hi there, I don’t think amaranth flour will work as a direct replacement as it needs more cooking. Maybe adding a splash of water for a wetter dough then baking for longer will work – but I’m just guessing. I wish i had loads of amaranth flour- haven’t had any for years

    1. Bastian Durward

      About 60 calories per healthy oat cookie, check out the top of the recipe where I always include it

      1. I tried the Apple ones but there’s nothing to hold it together? Ended up adding butter and make syrup so a half crumble/biscuit.

        1. The apple almond ones? I find with the soaked almonds and oats it’s enough to hold it together quite firm. But natural variation and no banana like this one do make it less firm

    1. Thank you for this recipe…I’ve baked similar cookies before. Today I added 2 tbsp. broken roasted almonds, 2 tbsp. sunflower seeds and two dates. I’ll let you know 🙂
      Here’s a question from my 14 year old…”Why are they called “cookies”…aren’t they really “bakies?”

  2. What is the best substitute for bananas? My son and I are allergic to bananas and most latex fruits. Can I use applesauce…if yes, how much would I need?

    1. Bastian Durward

      Sorry to hear that, I think you’d need a different recipe all together for this one I’m afraid. I’ve got a recipe for quinoa cookies if that suits better?

  3. Donna Belnick

    These are SO SO good! I just made them for the first time. Only change was, in addition to the required three ingredients, I also threw in some chopped dates and some toasted walnuts. I am now going to have to double my banana purchase each week! Love the idea of adding toasted almond some time. These will definitely be added to my “regulars” list. THANK YOU!

  4. I always love to try your 2-3 ingredients recipes because I don’t need to go out shopping for so many other ingredients that I will probably not use again. So I had bananas and oatmeal. Didn’t have raisins so I substituted with dates. I also had mixed nuts so I added a couple to the mix. Pretty good for easy and healthy. Thank you. Keep them coming.?

  5. I love this recipe idea. I’m using steel cut oats instead of rolled oats. Also adding finely chopped apples to the raisins and bananas. I hope all turns out well.

  6. Patrizia Verrelli

    I just discovered the recipe and i will make them very soon, but, can you use the rolled oats as they are? I would prefer them chunkier
    Is it necessary to grind them?

    1. I only add one small one or half a large apple. Sometimes I make small cubes of apple rather than blending at all

    1. Yes I think they should work, that’s the whole foods brand? As long as they’re quick cook they’re perfect for this easy cookie recipe

  7. Maybe it’s a taste buds thing. These were not so tasty for me. And Oats and Bananas are my absolute faves. I followed it to the T. Thanks for sharing though. I’ll be trying your other recipes…

    1. Bastian Durward

      Ah sorry to hear that, were you bananas overripe and very sweet? Maybe try adding some extras to it to make it sweeter if that was the issue? Actually what with the issue that made them not tasty?
