5-Ingredient Banana Oatmeal Breakfast Cookies
These oatmeal breakfast cookies are soft, chewy, and naturally sweetened with ripe banana. They come together in one bowl with just a handful of pantry staples, and they genuinely keep you full until lunch.
No flour, no eggs, and no added sugar beyond a drizzle of maple syrup. They are quick enough for a weekday morning and sturdy enough to toss into a lunchbox.
What Makes These Breakfast Cookies So Good
I love that these have the texture of a soft-baked cookie without turning into a sugar crash later. The banana and peanut butter keep them moist and a little dense, while the oats give them that satisfying chew.
They taste like a banana bread muffin in cookie form, but with zero guilt. A small handful of dark chocolate chips melts into little pockets, so every bite feels like a real treat even though the ingredient list is totally clean.
Ingredients
- 2 cups rolled oats: old-fashioned oats hold their shape best; use certified gluten-free if needed
- 2 large ripe bananas, mashed (about 1 cup): the browner the banana, the sweeter the cookie
- 1/4 cup natural peanut butter or almond butter: stir well if the oil has separated
- 2 tbsp pure maple syrup or honey: adds just enough sweetness without making them cakey
- 1 tsp vanilla extract: rounds out the banana flavor
- 1/2 tsp ground cinnamon: don’t skip it; it makes them smell like a bakery
- 1/4 tsp baking powder: helps them puff slightly, but you can leave it out in a pinch
- Pinch of fine sea salt: only if your nut butter is unsalted
- 1/4 cup dark chocolate chips or chopped walnuts: completely optional but really nice
Variations / Substitutions
- Nut-free: replace the peanut butter with sunflower seed butter or tahini; the flavor shifts a little but the texture stays the same
- Sweetener: agave nectar works in place of maple syrup, or skip it altogether for super-ripe bananas
- Mix-ins: dried cranberries, chopped dried apricots, or unsweetened shredded coconut all work well; stick to about 1/4 cup total so the dough holds together
- Spice it up: swap the cinnamon for pumpkin pie spice or add a small pinch of nutmeg
If you like these, you’ll also get a kick out of banana oat muffins made with the same set of ingredients.
How to Make Oatmeal Breakfast Cookies
Step 1: Mash the Banana and Mix the Wet Ingredients
Preheat your oven to 350°F (175°C) and line a large baking sheet with parchment paper. In a medium mixing bowl, mash the 2 ripe bananas with a fork until mostly smooth, leaving a few small lumps. Stir in the 1/4 cup peanut butter, 2 tablespoons maple syrup, and 1 teaspoon vanilla. Keep stirring until everything is a uniform color and no streaks of nut butter remain.
The mixture should look like a glossy, thick batter at this point. It’s okay if there are tiny bits of banana, they will soften in the oven.
Step 2: Stir in the Oats and Dry Ingredients
Add the 2 cups rolled oats, 1/2 teaspoon cinnamon, 1/4 teaspoon baking powder, and the pinch of salt right on top of the wet mixture. Sprinkle in the 1/4 cup chocolate chips or walnuts if you are using them. Use a spatula or wooden spoon to fold everything together until the oats are fully coated and the dough is cohesive.
It will seem a little wet at first, but the oats will absorb moisture quickly. If the dough feels too dry to hold together, add a teaspoon of milk or water, just enough so it clumps when you squeeze it.
Step 3: Shape the Cookie Dough
Scoop a rounded tablespoon of dough and roll it gently between your palms into a ball. Place it on the prepared baking sheet and flatten it slightly with the back of a fork or your fingers, because these won’t spread much on their own. Repeat with the rest of the dough, spacing the cookies about 2 inches apart.
You should get 12 to 14 cookies total. Try to make them even in size so they bake at the same rate.
Step 4: Bake and Serve the Cookies
Slide the sheet into the oven and bake for 12 to 15 minutes. The cookies are ready when the edges look dry and lightly golden, and the tops feel set when you press them gently. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
Serve them warm or at room temperature. They are especially good with a cold glass of milk or alongside a bowl of yogurt and fresh fruit.
A Few Notes Before You Start
- Use really ripe bananas: the peel should be heavily spotted or even brown. This is where all the natural sweetness comes from, and underripe bananas will make the cookies bland and starchy.
- Don’t skip the flattening step: these cookies hold their shape in the oven, so if you leave them as balls, you will get little domes instead of nice round cookies. Flatten to about 1/2 inch thickness.
- Measure the banana by mashing first: aim for about 1 cup of mashed banana total. If your bananas are small, you may need three, and if they are huge, one might be enough.
- Swap the peanut butter for almond or cashew butter: if you prefer a milder flavor. Tahini gives them a slightly savory twist that pairs well with a handful of raisins.
Storing Leftover Breakfast Cookies
- Refrigerate: keep them in an airtight container in the fridge for up to 5 days. They stay soft and the banana taste deepens a little as they sit.
- Reheating: a quick 15-second zap in the microwave makes them taste freshly baked again, or pop them in a toaster oven for a few minutes.
- Serve cold: they are perfectly good straight from the fridge, especially in lunchboxes or as an on-the-go snack.
What Goes Well With These Cookies
A tall glass of cold milk is the obvious choice, but they are also great crumbled over a bowl of plain Greek yogurt with a drizzle of extra honey. For a fuller breakfast, pair one with a smoothie that has a little protein powder, the flavor balance works without either one taking over.
Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes, quick oats give you a slightly softer, more uniform texture. The dough will absorb moisture faster, so you may need to let it sit for a minute before shaping.
Are these cookies gluten-free?
They are if you use certified gluten-free rolled oats. All the other ingredients are naturally gluten-free.
Can I make them nut-free?
Definitely. Replace the peanut butter with sunflower seed butter, and skip the walnuts. Use safe chocolate chips or raisins instead.
What can I use instead of banana?
Unsweetened applesauce is the closest swap, about 1 cup total. The cookies will be a little lighter in color and less sweet, so you might want to add an extra teaspoon of maple syrup.
Why did my cookies turn out crumbly?
That usually means the banana wasn’t mashed into a fully cohesive paste, or the peanut butter was too dry. Next time, make sure the wet mixture is very smooth before stirring in the oats, and add that splash of milk if the dough feels stiff.
