A nice dessert that can be prepared in advance and just finished in the oven: Pancakes filled with blueberries, served warm with a light cinnamon-vanilla sauce.
A recipe from my Mom: Apfelpfannkuchen (German for "apple pancakes"). Slices of apple, dipped into pancake batter, pan-fried and sprinkled with sugar and cinnamon. Enough for a main dish but also nice as a dessert.
