Recent reviews of Buttercream Cupcake Decorating Class: Rose, Daisy, Scabiosa

  • 5/5 from Astrid Liu, attended Nov 2026: Youngsuk was an amazing teacher! She taught us so many little tips for how to handle the buttercream, from getting it into the piping bag to mixing colors to switching out piping tips. She provided the prettiest tea and snacks at the start of class, demonstrated three kinds of flowers, then even corrected our piping Patrick Swayze in Ghost style! And she took pictures for each of us with our decorated cupcakes. Will be taking her other classes, and recommend that you do too!!!
  • 5/5 from Sabine Roehl, attended Nov 2026: 5 stars, no notes, this class is incredible! The host/instructor is very welcoming, knowledgeable and thorough, I cannot believe how much we learned in just 3 hours. The atmosphere is fun, light snacks and delicious tea in the cutest vintage cups were provided and all the tools and ingredients were impeccable and perfectly thought out. Highly recommend!
