Return the form to the oven and bake for about 15 minutes, until the filling thickens.
Allow the finished casserole to cool at room temperature until warm, without removing it from the mold, then put it in the refrigerator.
In the morning, remove the casserole from the refrigerator, cut into pieces and serve. It is better to cut with a dry hot knife. Not cheesecake, of course, but very tasty!
If you want, you can let the casserole warm up to room temperature, but I like it cold, it tastes better to me.
