Prepare the Candy: In a small pot, heat the 100 g of sugar and 50 ml of water over medium heat. Allow it to cook without stirring until a golden color is achieved. Once ready, pour this caramel into a metal mold, covering the base evenly.
Prepare the Cheese Mixture: In a mixing bowl, combine the 8 eggs, 200 g of sugar, 1 liter of milk, and 1 teaspoon of vanilla essence. Beat well until smooth and homogeneous. Carefully pour this mixture into the mold containing the caramel.
Cooking: Set the mold in a water bath by placing it inside a tray filled with hot water. Bake at 180 °C (approximately 350 °F) for 30 to 40 minutes. Check for doneness by inserting a stick; it should come out clean. Once ready, let it cool to room temperature.
Chill and Unmold: Refrigerate the dessert for at least 3 hours to set and firm up. When ready to serve, run a knife around the edges of the mold and invert it onto a plate. Optionally, decorate with dulce de leche, cookies, or any topping of your choice!
