FYI, when I was there in August, most of the Starring Rolls cupcakes were also at the Trolley Car Cafe (Starbucks). Not sure what time they are put out at either place.
Trolley Car Cafe cupcakes:

Chocolate Toffee = Butterfinger at Starring Rolls
Elsa (vanilla cupcake with buttercream icing)
Olaf (carrot cake cupcake with cream cheese icing)
Anna (Chocolate cupcake with buttercream icing)
Chocolate Peanut Butter
The only other cupcake at Starring Rolls was Red Velvet.
The Frozen-themed cupcakes could be found at other quick service restaurants as well.
So unless you were dying for the Red Velvet Cupcake, there was no need to make a special trip to Starring Rolls for the cupcakes.
Not sure what they're serving now.
