3-Ingredient Banana Oatmeal Chocolate Chip Cookies
All you have to do is…Mash, Mix, Scoop and Bake to create delicious Banana Oatmeal Chocolate Chip Cookies when you want something sweet but not too sweet.
These soft banana oatmeal chocolate chip cookies use just three main ingredients: ripe banana, large-flake rolled oats and semi-sweet chocolate chips. They are quick to mix, easy to shape and ready in about 15 minutes.
For Halloween, you can add a small amount of orange food colouring to the mixture and shape the cookies into simple pumpkin-style rounds. It is an easy seasonal variation without changing the basic three-ingredient recipe.
Our son is only two-years old and loves to eat cookies although he doesn’t get them every day. I haven’t met any kids who aren’t fans of cookies and to keep them healthy I wanted to make something that he could enjoy but without all the dad guilt.
One of the first words he learned after “Dad” was banana and probably because he’s a huge fan of bananas and peanut butter. Oddly enough he’s going to be dressed as a monkey for Halloween with a banana hanging out his pocket. (Not a real banana)

Lately he’s been on the apple binge but now that I’ve made a batch of these Banana Oatmeal Chocolate Chip cookies he runs in and out of the kitchen saying, Garana.He hasn’t quite mastered the letter B for banana yet although he can say it and recognize it so Garana it is.
Since our son is still teething one of the highlights of these Banana Oatmeal Chocolate Chip cookies are that they are soft which is why kids love them.
I didn’t invent this cookie but remember reading about it somewhere online or on Facebook, I can’t remember. It’s pretty hard not to remember the ingredient list which consists of three ingredients, Banana, Oatmeal and Chocolate Chips.
I bet you already guessed that though. The key to making these cookies perfect, round and soft is all in the technique which I explain in the recipe below.
Mash, Mix, Scoop and Bake
You can jazz up these Banana Oatmeal Chocolate Chip cookies up if you wish by adding
- a touch of vanilla,
- raisins
- sunflower seeds
- chia seeds
- hemp hearts
Feel free to add chopped nuts instead of chocolate although you’d be making them sugar-free so keep that in mind. If someone has a peanut allergy this may not be the best option either.
You may also want to consider add a touch of honey, maple syrup or sugar for flavour if you do that and a pinch of salt.
Since it is Halloween this week and I’ve already posted my widely popular Witches Finger Cookies back in 2012 along with a few other harvest type recipes I thought I’d go with something for the kids.
- Harvest Apple Caramel Muffins
- Magically Moist Apple Cake
- Apple Turnovers
- Pumpkin Brownies
- Pumpkin Biscotti with pumpkin spice icing
- Pumpkin Spice Scones glazed with icing
I hope you enjoy your Halloween and get your kids involved when making these Banana Oatmeal Chocolate Chip cookies like we did. Our son loves to mash the banana, add the oats and the chocolate chips. There’s nothing wrong with teaching your children to cook and have fun in the kitchen from a young age.
Don’t over-bake these cookies as they only take about 10 minutes to bake evenly on a Silpat (not affiliate) or a non-stick baking sheet at 320 degrees. It may take longer depending on the type of oven you use and baking sheet but generally if you smell the cookies baking then gently lift one up to see if it’s browned a bit underneath. You can also use your finger to press on the cookie gently to see if it’s come together.
How to make banana oatmeal chocolate chip cookies
We decided not to decorate the cookies with coloured buttercream frosting however if it’s a special occasion such as Halloween, Christmas, Valentine’s Day, Easter and so on you can invite the kids to frost them.
I hope you enjoy and whoever came up with this recipe… you’re awesome!

3-Ingredient Banana Oatmeal Chocolate Chip Cookies
Soft banana oatmeal chocolate chip cookies made with just three main ingredients: ripe banana, rolled oats and semi-sweet chocolate chips. Add orange food colouring for a simple Halloween pumpkin-cookie version.
Ingredients
- 1 large banana
- 1 cup of large flake rolled oats (not instant oats)
- 1/2 cup chocolate chips semi-sweet
- Optional: Coconut, raisins, sunflower seeds, chopped nuts, chia seeds, hemp hearts, all-natural peanut butter. See notes in post above.
Instructions
- Preheat the oven to 320°F and line a baking sheet with a silicone baking mat or parchment paper.
- Mash the banana thoroughly in a medium bowl.
- Stir in the rolled oats and semi-sweet chocolate chips until evenly combined.
- Scoop the mixture into 9 portions and shape each one into a round cookie. These cookies do not spread much while baking, so shape them before they go into the oven.
- Bake for 7 to 10 minutes, checking near the 7-minute mark. The cookies are done when the bottoms are lightly browned and the cookies have set.
- Let the cookies cool on the baking sheet for a few minutes before serving.
- For a Halloween version, add a small amount of orange food colouring to the mixture before shaping the cookies.
Notes
Use large-flake rolled oats rather than instant oats. Optional add-ins include raisins, coconut, sunflower seeds, chia seeds, hemp hearts or chopped nuts. If serving to children or guests, check for food allergies before adding nuts or peanut butter.

Are you sure it’s not meant to be 350degrees in the oven . Mine were not done after 10 minutes at 320
Hi Darren,
No I purposely set the oven lower than 350 since there are only 3 ingredients and I didn’t want them to burn. In the post I mention that depending on what oven you use, type of bakeware etc. it could take a bit longer. Generally if I smell whatever I’m baking I check on it because that means it’s close to being done. I like to underbake cookies because once they cool they are soft and chewy. If you want a hard cookie then bake them a bit longer. I hope that helps. 🙂 We love them.
I made these today to take with me while visiting my son, who eats low carb. They were a big hit with both DS and his roommates!
I doubled the recipe and added about 1/2 cup peanut butter and a handful of sunflower seeds along with the chocolate chips. Used slipats and baked at 350 for about 10 to 12 minutes till browned on the bottom
Next time, will try raisins
and apples, such a versatile cookie! Thank you!
Hi Bonnie,
Thanks!! I also made them again adding in a few extra bits the other day as we always seem to have an extra banana every week. This time around they took 10 minutes for us. It really depends on the oven but for the most part I always just watch my cookies I don’t rely on times as oven temps vary. Thanks.
If he likes low carb you could also add hemp heart or chia seeds as well for a bit of crunch!
