Whereas ice cream is a byproduct of milk, which is milked from cows, sprinkles are a byproduct of dreams, which are milked from fairies. Concoct dream-cream delicacies with today's Groupon: for $40, you get a cupcake decorating class at Le Dolci (an $80 value) on Portland Street. This deal is valid for any $80 value cupcake decorating class on the schedule.

Le Dolci offers lighthearted classes aimed at mastering the delectable cupcake arts in a frosting-festooned education studio. The introductory Cupcake Basics class ($80) suits a range of culinary capabilities, introducing students to tools and techniques used by professional cupcake whisperers. Explore the potential of sugar paste and food colouring to make simple sugar flowers and roses, and learn how to pipe smooth buttercream frosting into artful, taste-bud-tickling swirls. Other class options include the monthly themed special occasion decorating class (such as April's royal wedding cupcakes), a raw cupcakes class on no-bake dessert preparation, and others. Intermediate level classes are also available for those who have crossed paths with cupcakes before and know their frosty tricks.

Following a sweets-saturated course, students will not only deepen their appreciation for pastries, but also spare countless cupcakes from the embarrassment of showing up to parties bald. Some classes use nut products, and those with allergies should inquire about nut use before making a reservation. All materials are provided.
