Baked Apple Slices with Cinnamon Sugar

Melt the butter in a small pot over low heat. Mix the flour with the baking powder in a bowl.

In a large bowl, whisk the eggs with the milk, granulated sugar, vanilla sugar, and a pinch of salt. Add the flour-baking powder mixture, stirring constantly until a smooth batter forms. Finally, stir in the melted butter and let the batter rest for about 10 minutes.

Meanwhile, peel the apples, remove the core, and cut the apples into slices about 1 cm thick. Mix the apple slices with the ground cinnamon.
