Let me share how to make these peanut butter banana oatmeal cookies.
How To Make 4-Ingredient Banana Oatmeal Cookies
It’s ridiculously easy to make these 4-Ingredients Banana Cookies using basic wholesome ingredients.
All you need to make these healthy banana cookies are:
- Ripe Bananas – the ones with black spots on their skin, the ones that you won’t eat but are actually the most delicious in your baked goods! Naturally sweet with a strong banana flavor.
- Quick Oats – you can use old-fashioned rolled oats, but their texture is rough and much dryer, so I generally prefer the finer texture of quick-cooking oats for these cookies. Use a gluten-free certified oat brand if you are sensitive to gluten.
- Natural Peanut Butter – or sunflower seed butter for a nut-free option. The recipe works well with any other nut butter, including almond butter or cashew butter.
- Dark Chocolate Chips
Mashing The Bananas
First, peel and mash the ripe bananas with a fork or potato masher. I found the cookies to be much better and less dry if you pulse the bananas into a smooth banana puree with very tiny lumps.
Measure the amount of mashed banana using measuring cups. This also prevents disappointment with the texture.
Most problems with banana cookies come from a wrong ratio of dry ingredients to wet ingredients.
This is because bananas have different sizes and weights, so you should always measure them mashed before baking with bananas.
Stirring In Liquid Ingredients
Stir in the peanut butter until it forms a smooth banana peanut butter batter.
Finally, stir in the quick oats and chocolate chips. If the dough is too hard to be stirred with a spoon, use your hands to squeeze and combine ingredients.
The cookie dough should be sticky, and slightly wet but not too dry or runny either.
Fixing The Batter
If your cookie dough is too wet, add more quick oats. Stir in 1 extra tablespoon at a time until the dough is easy to shape into cookie dough balls.
On the other hand, add some more mashed bananas to fix a too-dry batter.
Shaping Banana Cookies
First, grease your hands with coconut oil to prevent the cookie batter from sticking to your fingers.
Next, line a cookie sheet with parchment paper lightly oiled with coconut oil. Set it aside.
Shape cookies with about two tablespoons for each. Scoop out the batter onto a cookie tray, leaving about a thumb space between each cookie.
Press each cookie dough ball with your hands to slightly flatten the cookies.
Bake the cookies in the center rack of the oven at 350°F (180°C) for 12-15 minutes or until the sides, and the top of the cookies gets golden brown.
You can tweak these banana cookie recipes by adding some ingredients below:
- For a boost of sweetness, add 2 teaspoons of liquid sweetener or 1 tablespoon of coconut sugar.
- For crunchy bits, add 1/4 cup of chopped walnuts or pecans.
- For a vegetable boost, stir in 1/3 cup of grated carrots or zucchini.
Banana cookies are always very soft, slightly crispy on the edges by not crunchy.
They are perfect for kids and easy to eat, even for toddlers.
These banana oat cookies must be stored in the fridge in a sealed container. They last for up to 3 days.
Another option is to freeze the banana oatmeal cookies in zip-lock bags and thaw them in the fridge the day before.

4-Ingredient Banana Oatmeal Cookies
- 2 teaspoons Maple Syrup
- Preheat the oven to 350°F (180°C). Line a cookie sheet with parchment paper. Lightly oil the paper with coconut oil. Set aside.
- Peel, mash the bananas with a fork or potato masher into a liquid puree. If too many lumps, the cookies end up dry, so mash it very well.
- Measure 2/3 cup not less or more to avoid dry cookie and stir in a bowl with peanut butter and maple syrup (if added).
- Stir in the quick-cooking oats (not rolled oats!) and chocolate chips. The cookie batter should be sticky, thick. If too wet, add more quick oats. If too dry, add more mashed banana.
- Scoop one tablespoon of batter, slightly grease your hands with coconut oil and roll into a ball.
- Place the cookie dough ball onto the prepared cookie sheet. Flatten with your hands and repeat until you have formed 10 cookies. Leave half a thumb of space between each cookie – they won't expand in the oven.
- Bake for 15-18 minutes or until golden brown on sides and top. The longer you bake the cookies, the crispier they are on the edges, but the center should stay soft and moist.
- Cool on the cookie rack for 10 minutes, then transfer them to a wire rack.
- Store up to 3 months in the fridge on an airtight cookie jar or freeze in zip lock bags and thaw at room temperature the day before.
