Add melted butter to bottom of 9 x 13 pan. Cut each cinnamon roll into 8 pieces and add to pan evenly.

Mix next 5 ingredients well and pour over cinnamon rolls. Refrigerate for at least 1 hr. But you can bake right away if you need a sugary cinnamon rush immediately !

Preheat oven to 350 and bake for 45-55 min or until a knife inserted comes out clean.

Pour reserved icing on top and spread evenly.
