We ordered 250 mini cupcakes for our wedding in 4 different flavors (Chocolate Caramel Sea Salt, Cookie Dough, Carrot, & a few gluten free) and they were all fantastic! The GF was as good as a regular cupcake! Only thing I would say is that the boxes they come with need a bit more attention as cupcakes tip over in box to easily.
Best think is because real buttercream we picked up day before wedding and they were still amazing 4 days after (had some left for the house!)
