Peel the banana and mash it on a plate with a fork until you get a smooth puree.

Place the mashed bananas and oat flakes in a deep bowl. Stir well. You will obtain a dense and slightly sticky mixture.

Add an egg to the mixture.

Chop the nuts finely with a knife.

Add the prepared nuts, raisins, and sugar to the banana and oat mixture. It is recommended to soak the raisins in boiling water beforehand to make them softer.

Stir all ingredients until you get a smooth mixture. This will be the dough for the cookies.

First form balls from the oat dough, then flatten them. Place the cookies on a sheet of parchment paper. Bake them in the oven at 180°C for 20 minutes.

Allow the biscuits to cool, then serve. They are slightly dry on the outside and slightly moist on the inside. Ideal for tea!
