Preheat oven to 180 º C/350 °F. Mix all wet ingredients together (milk, yoghurt, banana, honey & egg). Then add the rest of the ingredients and mix until everything is combined.
In a greased or lined baking pan (20 x 30 cm ) (8 x 12 inch) pour in all of the batter and spread it out evenly. Top it with a few berries to make it look even more tasty, and then you bake it in the oven for 30 min.
When the cake is done remove and set a side to cool. When the cake is completely cooled down, remove it from the pan and use a sharp knife to cut it into 12 breakfast bars.
The bars freeze well and they stay moist and delicious in the fridge for up to 5 days. I like to make a big portion and freeze half of it in single portions on order to have a easy breakfast or snack on busy days.
Eat the bars as they are, on-the-go, with a cup of coffee or serve them with a dollop of yoghurt or crumble them on top of your favourite fruit or yoghurt bowl :)
