Use a steel ring mold to get bundt shape. Pour the Caramel in the mold and give it 5 to 6 minutes to set.
Now pour the warm custard mixture over the caramel-coated mold, and spread it evenly.
Let it cool to room temperature, then refrigerate for at least 1 hour (longer if you can wait — it tastes even better chilled!).
Once set, gently loosen the edges with a knife, flip onto a plate, and admire the glossy caramel top dripping over the soft, creamy custard base.
Slice, serve, and enjoy every spoonful of this nostalgic dessert!
