Pennsylvania Dutch Amish Dessert

Preheat your oven to 350°F (175°C) and lightly grease a 9-inch baking dish or pie pan to prevent sticking.

In a large mixing bowl, beat the eggs thoroughly until they are light and well combined.

Add the sugar, sour cream, and vanilla extract to the beaten eggs, then mix until the filling is smooth and fully incorporated.

Pour the custard filling evenly into the prepared baking dish, smoothing the top with a spatula.

Place the baking dish in the preheated oven and bake for 40 to 45 minutes, or until the custard is set and a knife inserted in the center comes out clean.

Remove the baked custard from the oven and allow it to cool completely at room temperature before adding the topping.

Prepare your desired topping, such as a sweetened sour cream mixture combined with the remaining sugar, and spread it evenly over the cooled custard.

Refrigerate the finished dessert for at least one hour before serving to allow the topping to set and the flavors to meld.
