How to make
Beat the butter and sugar. Add the egg and yogurt. Sieve the flour with the baking powder and vanilla.
Beat everything well with a mixer. Pour the batter into a baking tin (9 1/2″ (24 cm)). Top with the berries and sprinkle with sugar.
If using frozen berries, do not thaw them before baking (sprinkle them with a little starch). In a preheated oven, bake at 390°F (200 °C) for approximately 25 minutes.
