Some recipes feel like they’ve always been part of your kitchen, even if you just came up with them last week. These soft oat cookies are exactly that kind of recipe for me – something so simple, so familiar, and yet so comforting, it’s like they’ve always belonged in my day-to-day life. They’re made with just a handful of wholesome ingredients – bananas, oats, blueberries, an egg, and a little nut butter – but somehow the result feels way more special than the sum of its parts.
I first made these on a slow afternoon when I craved something baked but didn’t want anything heavy or too sweet. You know those days when you just want a cozy bite with a cup of tea or something to grab between tasks that won’t give you a sugar crash afterward? That was one of those days. I looked at the bananas slowly ripening on the counter and remembered those classic three-ingredient banana-oat pancakes we all know and love – and thought, what if I just made that... but in cookie form?
The base is incredibly simple: mashed banana, rolled oats, and one egg. But a few small additions really bring it to life – a spoonful of nut butter for richness, a pinch of cinnamon for warmth, and a handful of blueberries that turn juicy and jammy in the oven. I like to think of these cookies as the love child between banana bread, pancakes, and muffins – only way easier to make, and healthier too.
What I especially love is that these cookies are soft – not crunchy or crumbly like a traditional cookie – but moist, chewy, and naturally sweet. They’re perfect fresh out of the oven, but honestly just as good the next day, especially if you keep them in the fridge. There’s something very real and honest about them. You don’t need any sugar, flour, or butter, and yet they feel like a treat. The kind of recipe that reminds you how much goodness you can get from very little.
And it’s not just that they’re healthy – it’s that they’re versatile. You can swap the blueberries for raspberries or chopped strawberries, use almond butter instead of peanut butter, or even stir in some chopped nuts, coconut flakes, or dark chocolate pieces. They can be made dairy-free and gluten-free too, if you use certified gluten-free oats. They’re great for lunchboxes, breakfast on the go, or even as a light dessert.
Sometimes I’ll make a batch in the evening just because I want something warm from the oven – they take almost no effort, and the smell of cinnamon and banana baking is a kind of comfort in itself. And let’s be honest – if a cookie can feel both indulgent and nourishing at the same time, it’s a winner in my book.
So if you’ve got some ripe bananas lying around and a handful of oats, you’re already halfway there. These cookies aren’t fancy, and they’re definitely not Instagram-perfect with frosting and layers. But they’re real. They’re the kind of treat that makes you slow down for a minute and appreciate how satisfying simple food can be.
You will need:
For ~10 cookies
* 2 ripe bananas
* 1 egg
* 130 g rolled oats
* 100 g fresh or frozen blueberries
* 1 tablespoon of nut butter (about 15 g)
* ½ teaspoon cinnamon
* ½ teaspoon baking powder
* a pinch of salt
Preparation
1. Preheat your oven to 180 °C (350 °F).
2. Mash the bananas with a fork in a large bowl until smooth.
3. Add the egg, nut butter, cinnamon, salt, and baking powder. Mix well to combine.
4. Stir in the oats. The dough should be thick and sticky.
5. Gently fold in the blueberries. Be careful not to overmix, especially if using frozen berries – you want to avoid turning the dough purple.
6. Scoop the dough with a spoon onto a baking sheet lined with parchment paper. Flatten them slightly into cookie shapes.
7. Bake for 15–18 minutes, or until the edges are lightly golden and the cookies feel set. I personally baked for 20 minutes.
8. Let cool for a few minutes on the tray before moving to a rack to cool completely.
