Preheat the oven to 180°C (350°F) and grease a round baking pan.
In a mixing bowl, combine flour, sugar, and softened butter.
Add an egg and mix until a soft dough forms.
Press the dough evenly into the bottom of the prepared baking pan.
Arrange fresh raspberries over the dough in an even layer.
In a separate bowl, whisk together eggs, cream, sugar, and vanilla extract until smooth.
Pour the creamy mixture over the raspberries.
Bake for approximately 35–45 minutes until the filling is set and the crust becomes lightly golden.
Remove from the oven and allow the Kuchen to cool completely.
Refrigerate for a short time if you prefer a firmer custard texture.
Cut into slices and serve with coffee or tea.
