Ingredients

• Between 300 and 400g peeled bananas
• 1 egg
• 20g sugar
• 10g baking powder
• 2g xanthan gum
• 200g gluten-free flour

Steps

Preheat the oven to 200℃.

Place a large bowl on a scale, peel and add bananas until reaching 300 to 400g. Mash them with a fork, then add the egg, sugar, baking powder and xanthan gum. Mix well, until all ingredients are incorporated. Add the flour and mix until the dough looks uniform and all lumps are gone.

Butter a cake tray and fill it with the dough. Flatten the surface, then score it with a knife or a fork. Cook for 1h, or until it is golden. Keep an eye on the cake for the last 15 minutes, as the cooking time can vary from oven to oven.
