Easy 2-Ingredient Banana Oat Breakfast Cookies

Bananas and oats are two humble ingredients that come together in a surprisingly delightful way with minimal effort. This simple breakfast cookie recipe is perfect for busy mornings or as a wholesome snack that you can grab on the go. The beauty lies in how just two main ingredients—ripe bananas and rolled oats—combine to create a soft, naturally sweet cookie without any added sugar. Mixing in chocolate chips, raisins, or nuts is optional but adds just the right touch of flavor and texture. A few small tweaks in baking time or the ripeness of your bananas can make all the difference to the final cookie’s texture, and these little extras have helped me get these just right every time for a pleasantly chewy bite that never dries out.

Ingredients

2 ripe bananas, mashed (about 1 cup / 240 g mashed)
1 cup (90 g) rolled oats
Optional add-ins (up to 2 tablespoons / 30 g):
- Chocolate chips
- Raisins
- Chopped nuts (walnuts, almonds, or pecans)

Ingredient Notes

Ripe bananas are key—they should be soft with brown spots for maximum sweetness and binding. Underripe bananas won’t mash well and may make your cookies dry or crumbly. Rolled oats work best for texture; instant oats are too fine and can create a gummy consistency. Quick oats can be used but expect a softer, less chewy cookie. Adding mix-ins like chocolate chips or nuts adds flavor and crunch but keep them minimal so the cookies hold together well.

Kitchen Tools Needed

Mixing bowl
Fork for mashing bananas
Baking sheet
Parchment paper or silicone baking mat
Spoon or cookie scoop
Cooling rack

Step-by-Step Instructions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper to prevent sticking.
In a mixing bowl, mash the bananas thoroughly with a fork until mostly smooth—it’s okay to leave a few small lumps as that adds texture.
Add the rolled oats to the mashed bananas and stir gently until just combined. If you’re using any mix-ins like chocolate chips, raisins, or nuts, fold those in carefully now.
Using a spoon or cookie scoop, drop 8 small mounds onto the prepared baking sheet. Flatten each mound slightly with the back of the spoon to help them bake evenly.
Bake for 13 to 16 minutes. The cookies should be set and lightly golden around the edges but still soft in the middle. Baking a minute or two less keeps them chewier, while longer baking gives a firmer texture.
Let the cookies cool on the baking sheet for at least 5 minutes to firm up before transferring them to a wire rack. Cooling on the sheet prevents them from falling apart.

Pro Tips

Use bananas that are very ripe for natural sweetness and moisture; under-ripe bananas won’t bind well.
Resist overmixing once the oats are added to avoid a tough cookie.
Flatten the cookie mounds to about ½-inch thick for even baking.
If your mixture feels too wet, add a tablespoon or two more oats; if too dry, a bit more mashed banana works.
Baking time varies based on your oven and banana moisture—start checking at 13 minutes to avoid dry cookies.
Letting the cookies cool fully on the pan helps them hold their shape better.

Common Mistakes

Using underripe bananas, which results in dry or crumbly cookies.
Not flattening the dough enough, causing uneven cooking with raw centers.
Adding too many mix-ins, which can make the cookies fall apart.
Overbaking leads to hard, less pleasant cookies—watch them closely near the end.
Skipping the cooling step on the baking sheet, which risks breaking cookies when transferring too soon.

Variations

Mix in 2 tablespoons (30 g) of peanut butter for a richer flavor and softer texture.
Swap raisins for chopped dried apricots or cranberries for a tart twist.
Use cinnamon or nutmeg (½ teaspoon) for warm spice notes.
Replace chocolate chips with white chocolate or butterscotch chips to vary sweetness.

Serving Suggestions

These cookies are great on their own or paired with a dollop of yogurt or nut butter for extra protein. They also make a handy on-the-go breakfast, lunchbox snack, or a post-workout treat. Serve with a glass of milk or your favorite tea for a simple and satisfying bite any time of day.

Storage Instructions

Store leftover cookies in an airtight container at room temperature for up to 3 days. For longer storage, freeze them in a sealed container or zip-top bag for up to 3 months. Thaw frozen cookies at room temperature before enjoying.

Reheating Tips

These cookies are best eaten at room temperature. If you prefer them warm, pop one or two in the microwave for 10–15 seconds to soften without drying out. Avoid reheating in the oven as it can make them too crisp or dry.
