How to cook
Preheat your oven to 180 degrees. Grease the muffin moulds. Sift the flour along with the baking soda and baking powder. Beat the egg in a bowl. Add the sugar, yogurt and oil to it.
Stir well. Peel the bananas and mash them. After that, add them into the mixture. Stir and add everything to the flour.
Once you have a smooth mixture, pour it into the muffin moulds and bake them in the preheated oven.
