My Best Idea Ever

Many Baskin & Robbins ice cream shops are also Dunkin' Donuts shops. This weekend, I had the following:

One large Ice Cream Cup

One cake donut on the bottom of the cup

A scoop of ice cream on top of the donut finishes off the masterpiece. I imagine I am not the first one to discover this...I just wonder why Baskin Robbins hasn't publicised it.
