You can choose to partake in just one individual Diploma module and receive a ‘Rosalind Miller Cake School Diploma Certificate of Excellence’ OR complete the full six modules to receive your ‘Professional Master Diploma Certification’. 


This is the Professional Diploma where we show you exactly how we do things in our own professional kitchen! During this in-depth 4-day Diploma you’ll learn all the fundamental skills for baking and buttercream icing the perfect cake every time (in a range of flavours). You’ll learn some of Rosalind’s delicious recipes, including her signature Vanilla sponge, velvety Belgian Chocolate cake and Lemon cake. We’ll also bake a Vegan Vanilla cake. Plus, we’ll show you ways that you can adapt the core recipes to create other exciting flavours. You’ll then learn how to expertly prepare your cakes and finish with flawlessly smooth buttercream covering with sharp edges.

We will guide you through the technique of safely and securely stacking your cakes and discuss important factors such as delivery and set-up.

Not only will you learn our fantastic repertoire of recipes, we will also teach a selection of decorating techniques including buttercream finishes and piping, palette knife painting, and decorating with fresh flowers

You’ll also be able to take a tour of our professional cake design studio and kitchen, and meet Rosalind and the team for Q&A where you can ask any cake questions you may have.

Our aim with this Diploma is that you leave with the confidence and the ‘know-how’ to make your cakes both look and taste fantastic. You’ll leave the class with a selection of beautiful centrepiece creations that you can use for your own portfolio or just to enjoy and share.
