Within a year, Marsha was requested to begin teaching decorating classes. A short while later, Marsha also began coordinating a large and active teaching staff in Houston, Texas, for an international cake and candy products firm.

Her talents have won her awards in many cake decorating techniques, including buttercream decorating, cocoa painting, royal icing work, foreign techniques, etc.

Marsha has planned and coordinated several cake shows, including being a co-coordinator for two large state shows in Texas. She also enjoys participating in shows as a judge and demonstrator.

Marsha's career and personal life came together when she met her soon-to-be-husband Roland Winbeckler (Roland's cake photos) at an ICES convention (international cake decorator's convention). She then moved from Houston, Texas, to Kent, Washington, where Roland resided at the time. In 2003, Marsha and Roland moved to Redding, California.

Roland and Marsha own and manage CakeSuppliesPlus.com--A-J Winbeckler Enterprises, through which they teach classes, produce and sell books and DVDs, and sell decorating products online. Cake decorating has taken them across the U.S. and to Australia, Jamaica, and Canada.

Marsha edited Winbeckler's Cake and Candy Chronicle, an international cake decorating newsletter (back issues available on our web site), for 17 years and the International Cake Exploration Societe (ICES) Newsletter for over 13 years. Marsha is currently on the Editorial Board for American Cake Decorating Magazine and a contest judge for Cakes We Bake, an online Cake Decorating Community.

Appearances on TV, including the Food Network's Sesame Street Cakes and TLC's Ultimate Cake Off, and demonstrating at international cake decorator's conventions (ICES) are among highlights in Marsha's career. 

She is the author of three books, Cocoa and Chocolate Painting, Wafer Paper Uses, and Decorating With Rolled Buttercream Icing, plus a candy DVD, Easy Chocolate Tempering and Candy Coating Uses.
