Ingredients
Instructions
Step 1
Preheat the oven to 175 degrees Celsius with a rack in the middle, and line a baking sheet with parchment paper. The oven needs to be hot from the start so the cookies set quickly instead of spreading. The oven is ready when the preheat light turns off and the sheet is lined flat.
Step 2
Peel 240 g very ripe bananas with brown-speckled peels, put them in a bowl and mash them very finely with a fork, then stir in 30 g peanut butter, 3 g vanilla extract, a pinch of ground cinnamon and a pinch of salt. The riper the bananas, the sweeter they are and the better they bind the oats. The mixture is ready when it is almost as smooth as cream, with only a few tiny bits of banana left.
Step 3
Add 160 g rolled oats to the banana mixture, along with 50 g chocolate chips if you are using them, stir well and let it sit for about five minutes. This short rest lets the oats soak up moisture from the bananas, so the mixture thickens and is easier to shape. The mixture is ready when it is moist and sticky and holds together in a mound when scooped.
Step 4
Drop heaping tablespoons of the mixture onto the sheet about 3 cm apart, then press each one flat with the back of the spoon into a round about 1 cm thick. These cookies don't spread in the oven, so shape them exactly the way you want them to look. They are ready when they are evenly round with neat edges and all the same thickness.
Step 5
Bake at 175 degrees Celsius for about 14 to 16 minutes, rotating the sheet once halfway through so they brown evenly. Baking them just long enough keeps the centers soft and moist, while baking too long turns them dry like crackers. They are done when the edges and bottoms are golden brown, the tops look dry and they feel firm when pressed lightly.
Step 6
Let the cookies sit on the sheet for about ten minutes before moving them to a wire rack with a thin spatula. While hot they are very soft and break easily, and they only firm up enough to move once they cool a little. They are ready when they don't bend as you lift them and the bottoms come away from the paper easily.

- Wire cooling rack
- Kitchen scale
Tips
- You can swap the chocolate chips for raisins, chopped walnuts or desiccated coconut to change up the flavor.
- If the bananas aren't ripe enough, the cookies will taste bland and won't hold together; wait a few more days until the peels have lots of brown spots.
- For crispier edges, press the cookies thinner and bake them for about two minutes longer.
Storage
Because they contain a lot of fresh banana, keep these cookies in an airtight container in the fridge and enjoy them within four days. You can also freeze them for up to a month and warm them in the oven for about five minutes.
Common problems and how to fix them
- The cookies are mushy and sticky in the middle.
- They were too thick or not baked long enough. Press them flatter and bake until the bottoms are clearly golden brown.
- The cookies crumble when lifted off the sheet.
- The mixture didn't have enough banana or you moved the cookies while they were still too hot. Use the full amount of ripe banana and let the cookies cool on the sheet for ten minutes.
