Pastry Chef Tiffini Soforenko (co-owner) puts vanilla buttercream onto a 'Vanilla Bean Cupcake,' while store manager and pastry chef, Anna Russell sprinkles 'jimmies'  onto them at Yummy Cupcakes on Thursday, just an hour before the store opened on Wilshire Boulevard.  All the cupcakes are baked from scratch daily. No mixes are used. Cupcakes that do not sell by the end of the day are donated to senior citizens homes or food banks. All employees at Yummy Cupcakes are graduates of culinary institutes and bona fide  pastry chefs.
