Preheat oven to 350 degrees

Butter a 1 1/2 quart casserole dish {cooking spray will work too} and set aside {I used a 9″ baking dish, but using a 9″ x 13″ pan would have worked better}.

Soak Grape-Nuts in boiling water for 1 minute. Strain and remove excess liquid.

Line the bottom of the buttered casserole dish with Grape-Nuts and set aside.

In a large mixing bowl, whisk together the milk, sugar, eggs, vanilla, melted butter and salt. Pour the mixture over the Grape-Nuts into a 9″ x 13″ casserole dish. Place the casserole dish in a large roasting pan and fill the pan with enough water to reach about 1 inch from the top of the casserole dish.

Bake for about 45 minutes or until the custard is set and the top of the custard is a nice golden brown color. Be careful not to over cook.

Cool completely before serving.
