Made my first dummy cake last weekend. The top tier is styrofoam, not cake. Don't worry, the bottom tier is delish banana cake. It was just for fun. Not really any different from covering a real cake. Just buy a styrofoam dummy cake from your local decorating store, brush with sugar syrup to make the surface damp, or water - whatever. Then cover with rolled fondant and decorate as usual.
Love that I could utilise the 2 tiers in decorating without then having that much actual cake. Hey, I love cake, but it is not my staple diet!
I have always loved the chocolate and pink combination of colours. It seems yummy and pretty at the same time. What do you think?
