What You’ll Need For Two Ingredient Banana Oatmeal Cookies:
- Quick Cooking Oats (you can also use old fashioned)

What oats are best?
Quick cooking oats are best for oatmeal banana cookies because they require less time to cook. Since the cookies only bake in the oven for 15 minutes, old fashioned oats would not have enough time to break down.
How to Make Banana Oatmeal Cookies
Detailed instructions and measurements to make healthy banana oatmeal cookies are listed in the recipe card at the bottom of this page.
- Preheat the oven to 350°F.

- Scoop the cookies on a parchment-lined baking sheet and flatten them slightly with a fork.

Possible Add-Ins

Some of my favorite mix-ins are:
- blueberries
- peanut butter
- raisins
- chocolate chips
- protein powder
- nuts
Storing Banana Oat Cookies
Once the cookies have cooled completely, store them in an airtight container. You can store on the counter top or in the refrigerator.
How Long do Banana Cookies Last?
These oatmeal banana cookies will last up to 3 days on the counter top and up to 5 days in the refrigerator.
How to Freeze 2 Ingredient Banana Oatmeal Cookies
You can freeze banana oat cookies. Place the cookies on a baking sheet in the freezer. Once they’ve frozen completely, remove them from the baking sheet and place them in an airtight container or freezer safe bag and store up to 6 months.
Oatmeal Banana Cookies FAQs
Be sure to press them gently with a fork to flatten them slightly. They will not spread on their own while baking.
Yes, the add ins are only optional. They are great on their own without any add ins.
Oatmeal is a whole grain full of vitamins, fiber, and minerals. Bananas are also full of nutrients like fiber, potassium, vitamin C, and vitamin B6.
These oatmeal cookies are healthy because they don’t contain any added ingredients. You’re only using oatmeal and bananas.
No, rolled oats and quick oats are not the same. Rolled oats (which are also called old fashioned oats) are better for baking because they do not break down as quickly and hold their texture better.
There are a couple of reasons why your cookies might be dry. The biggest culprit is typically that they’ve been overbaked. If you leave the cookies in the oven too long, they’ll lose moisture and begin to dry out. The other reason may be improper storage after baking. It’s important to keep them stored in an airtight container to retain moisture.

This is such an easy recipe and fun to try different add ins. Walnuts and blueberries, flax seed and chia seed make these nice and soft, but chewy. Delicious!
I made them without any add-ins and they were pretty flat in taste. Maybe add in blueberries next time. Have you ever added baking Splenda or cinnamon to these before? I’m trying to keep the cal count low, and realize many consider adding sucralose “unhealthy.” They are easy to make and a great use of overripe bananas…mine were VERY overripe, LOL!
Hi Lynn, I have added cinnamon and blueberries and enjoyed them. Were the very overripe bananas beginning to ooze? I’m wondering if that may have been the reason for the flat taste.
Lovely simple recipe. Made soft and chewy cookies. I found them sweet and delicious as is. Also looking forward to making variations. Super fun snack to share with my rabbits. This is a bunny safe and bunny approved recipe. They loved them too.
Amazing!! I added a little bit of baking powder, vanilla extract, and almond milk to it. Really did make it amazing!!
I love those alterations! Sounds delicious!
Absolutely delicious cookie! I’ve made with choclate chips and with raisins…super easy
