The Starbucks cupcakes baked in the starbucks cup, was it difficult to acquire the cups from the Starbucks manager? What size cup did you use? Does the cup size matter in regard to the way the batter bakes - does one size bake better than another?
MaryKatherine... you can read through the comments and it will answer most of the questions you asked. She mentioned she use to work at Starbucks and knows people so she just went in and asked for the cups. So not sure how hard it would be for just anyone to walk in and get them without some type of cost.
She used the "short" cups, 6oz.
