Recipe(tried): Whipped Shortbread

While in Canada a couple of years ago we visited the town of Niagara on the Lakes I think it was called. We went into a bakery there and bought some shortbread that would melt in your mouth. It was sort of puffy as I recall. Can anyone share a recipe for a mouth watering shortbread with me. Would greatly appreciate it.
