🧄 Ingredient notes
What do you need to make these cookies?
- ripe, spotty bananas
- rolled oats (old fashioned or quick cooking oatmeal)
- ground cinnamon
The ripe, spotty bananas offer sweetness and moisture. The oatmeal offers substance, nutrition and helps everything stick together.
And, the ground cinnamon is for flavor! You can switch up the cinnamon, if you'd like. See my recipe notes below for suggestions on alternative spices and flavoring.
No egg at all is required (or recommended) for these cookies. The bananas and oatmeal work in tandem to hold everything together.
So, that also means you can eat the batter, if you want (I won't tell).
All the stick togetherness in these breakfast cookies comes from the oatmeal and the mashed banana.
There's no need for flour and seeing as flour is higher in calories than a whole plant food like rolled oats, that's great for the waistline, too.

This is a 3 ingredient no sugar cookie recipe. Yay! The sweetness comes from the ripe bananas.
Since sugar usually plays the role of making cookies sweet and crispy, you can expect this cookie to be mildly sweet, chewy and somewhat dense.
Kind of like a soft breakfast granola bar that's ready in less than 30 minutes, start to finish.
Mash the bananas
You'll want them be mashed very well, with only very small chunks remaining.
Add oats and cinnamon
Stir in your rolled oats and cinnamon (or other spice).
Spoon and shape cookies, then bake!
Drop spoonfuls of batter on a baking tray and then shape them with your hands.
These cookies will not spread out, so make them into the shape, width and height you want from the beginning.
Take my advice and use a silicone mat or parchment paper to line your baking sheet, because these will stick without it.
- Use parchment paper or a silicone mat to bake these, otherwise they will stick.
- Shape with your fingers before baking.
- Mash your banana really well.
- You can make these cookies any size without adjusting the ingredients. You would only need to adjust the time in the oven.
- For smaller cookies, reduce the time by 3-5 minutes.
- A small 2-inch cookie size would be great for your kids to run around with snacking on.
- For large cookies, increase time in oven by 2-3 minutes.
- A large 4-inch cookie size (especially with added nuts, seeds or dried fruit) would make a filling breakfast on the run for you.
What if you wanna make these a little fancier?
There's all sorts of beautiful things you can stir in or top these 3 ingredient banana oatmeal cookies with, my favorites being dark chocolate or walnuts.
Try these toppings or mix-ins:
- Dark chocolate chips or shavings
- Walnuts (halved or chopped)
- Pecans (halved or chopped)
- Sunflower seed kernels
- Small smear of fruit preserves, jam or jelly, like blackberry preserves
- Peanut butter (or other nut butter) for making 4-ingredient banana oatmeal peanut butter cookies
- Fresh sliced berries
- Dried cranberries
- Flaxseed (a teaspoon mixed in)
- Wheat germ (a teaspoon mixed in works well)
👨👩👦👦 Serving suggestions
Kid friendly cookies
These simple, chewy cookies are great for a kids breakfast or snack throughout the day.
They keep, stored in the refrigerator, for 3-4 days, but do not have to stay chilled, so you can throw them in your kids' lunch box for school. Or, in your purse for running errands.
Since these cookies have no sugar, you can feel good about feeding them to your kids and toddlers. For toddlers that can't chew well yet, make sure and break up the cookie into small pieces for them.

3 Ingredient Banana Oat Cookies
- Preheat oven to 350 F. Peel and mash bananas in a medium bowl with a potato masher or fork. Make sure they are well-mashed, with only small chunks remaining.
- Stir in rolled oats and cinnamon. Set aside for a few minutes to allow the oats to soak up the moisture. If the batter is very wet/thin still, add 1-2 tablespoons of oats.
- Line a baking tray with parchment paper or a silicone baking mat. (Cookies will stick if you skip this step).
- Drop spoonfuls of batter onto baking tray and then shape with your fingers. Cookies do not spread out while baking, so shape them into the width and height you want them to be. This recipe will make about eight medium, 3-inch wide cookies.
- Add optional toppings, if using.
- Bake cookies for 17 minutes. *See notes for adjustments for smaller or larger cookies.
- Remove from oven and allow to cool slightly before enjoying.
