Preheat the oven to 375° Fahrenheit.
Fill a saucepan with water, and warm it over medium heat until it comes to a simmer.
In a small saucepan, cook the sugar over medium-high heat for 6-8 minutes or until it caramelizes and turns dark brown, swirling it around every few minutes. Be careful not to let it burn! Pour the caramel into a bundt pan, swirling it around to coat the edges.
1 cup granulated sugar
In a separate pot over medium heat, add the milk and heavy cream. Heat the mixture just until it is warm. Do not bring it to a boil!
3 cups whole milk, 1 ¼ cups heavy cream
In a bowl, beat the eggs and sugar until smooth. Working slowly, pour milk into the bowl. Stir in the vanilla.
9 large eggs, ½ cups + 2 Tablespoons granulated sugar, 2 teaspoons vanilla extract
Pour the custard filling into the bundt pan over the caramel. Place the bundt pan in a baking dish, and pour 2-3 inches of simmering water into the dish.
Bake 60-70 minutes or until the crème caramel is firm enough to hold its shape but still slightly jiggly when gently shaken.
Let the crème caramel cool at room temperature for 1 hour. Then, cover it with plastic wrap, and store it in the fridge for at least 4 hours or ideally up to overnight.
Run a thin knife around the sides of the bundt pan and along the center. Place a large serving plate over the pan, and invert the dessert onto the plate.
Serve cold, and enjoy!
Store covered in the fridge for up to 5 days.
