I finally saw these in my local Food Lion store- Frosting Creations are pretty interesting!
You buy the generic frosting and then select the flavor you like. Some of the available flavors are Bubble Gum, Cotton Candy, Mocha, White Chocolate Raspberry and Strawberry Shortcake.
Right now you can print a coupon to get a FREE Flavor Mix with the purchase of the Starter Frosting. I found it under zip code 23320 and “foods”.
