Preheat oven to 350˚F.

Cut donuts into chunks and place in large baking dish.

In a medium bowl whisk together condensed milk, eggs, salt to taste, and cinnamon. Pour the mixture over the chopped donuts and make sure donuts are coated.

Allow to soak for a few minutes (5 to 10) and then bake for about 40 minutes to an hour. Until the center is jelled, cooking time will very depending on the depth on the pan.

While it is baking whisk together melted butter and enough powdered sugar to give you the consistency you want. I used too much sugar and had to add a little milk in to thin it out.

Pour the sauce over your pudding and serve.
