The sugar journey began early on…. Ro grew up in an Italian household and, at an early age, was exposed to baking by her Italian speaking grandmother and decorating by her need to make her Mom’s creations pretty. Coupled with a love for baking, Ro experimented with recipes and sugar options, especially during her athletic years, which has led to her growing creation of her own recipes. Ro graduated from SDSU with a Bachelor’s Degree, has graduate studies under her belt; and, worked in the corporate world up until she had a life changing event which led her back to her love of baking and decorating.

As Ro created, she wanted to share her edible pieces and share her experiences, so she began “Cakes by Rosanne” in the late 90’s, and started teaching the basics of piping throughout the community. Yearning for additional knowledge, Ro attended Confectionery Arts School and studied with cake decorating greats and top pastry chefs since 2004. Ro’s passion for sharing led her to begin her own school of baking & confectionery arts and retail supply shop in North San Diego County in August 2008. She teaches both by demonstrating and hands on approach with the students, helping students throughout the class to do the techniques correctly. Ro teaches the basics to extreme cake building, fondant, carving, sugar art, and baking. Ro’s philosophy is to not only show the skill, but to make sure the student understands the mechanics of the skill so they are successful in execution. Her non-intimidating approach has led to hundreds of student success stories. She truly inspires others to follow their dreams of creating!
