What do you add to pillsbury cinnamon roll orange icing to make it more of a frosting of glaze?

I saw a woman making flat cakes on food network. She rolled out cinnamon rolls between two pieces of parchament and then pressed them in chopped pecans and baked them. Then she did something with the orange icing they make to make it more of a dip/glaze type thing. It looked sooooooo good but I cant remember what she did.
