Ingredients & Substitutions
These are the main ingredients and substitutions for 4 ingredient cookies. Scroll down to the recipe card for full ingredients list and instructions.
Use ripe bananas for best results. They are naturally sweet and easily mashed. For this recipe, about 3 small or 2 regular bananas are needed.
Old fashioned rolled oats add a delicious chewy texture. Both gluten free rolled oats and regular rolled oats work well. I do not recommend quick oats for this recipe.
All natural creamy peanut butter adds heartiness and flavor. In addition, the peanut butter makes these cookies filling. It adds protein too! Use an all natural peanut butter. The only ingredients should be peanuts and salt. Peanut butter with added sugars and oils is too thick.
Any type of chocolate chips work. I used mini for this recipe, but regular work well too. Dark, semisweet, milk and white chocolate chips are all great options.
Taste & Texture
These 4 ingredient peanut butter cookies taste like banana, peanut butter and chocolate. They are not overly sweet. The taste is a mix between baked oatmeal and banana bread.
The texture is chewy, soft and thick. The rolled oats add all the texture.
How to Make
First, preheat oven to 350 degrees Fahrenheit. Line a baking pan with parchment paper.
In a mixing bowl, add all ingredients.
Stir to combine.
Use an ice cream scooper to scoop out balls of dough. Then, place on lined baking pan.
Use hands to flatten each ball of dough. These cookies do not spread at all while baking.
Bake for 8 to 9 minutes.
Finally, remove from oven. Cool on pan for 5 minutes before transferring to a cooling rack.
Expert Tips & Tricks
Use ripe bananas for best results. They are naturally sweet.
Old fashioned rolled oats are much better than quick oats for these cookies.
Use all natural creamy peanut butter. It is slightly runny. Stir peanut butter well before measuring.
After scooping out balls of dough, flatten each cookie.
These 4 ingredient banana oatmeal cookies do not spread while baking. So, whichever shape they enter the oven, they will end up that way.
Store cookies in the fridge or freezer. Due to the banana, they become slightly brown after a couple days if left at room temperature.

These cookies are a great grab and go breakfast. Additionally, add them to kids’ lunches, serve as an after school snack or dessert.
Store cookies in the fridge for up to 4 days.
