– I decorated a six inch double barrel cake (which is 4 cake layers with a cake cardboard halfway up and 5 bubble tea straw supports beneath)- You could create a similar design on cakes of any size. – ▢Vanilla Buttercream- I used our fluffy vanilla buttercream- our classic buttercream is a good option also. – ▢Palette Knife- A small offset tapered spatula would give you a similar look if you don't have a palette knife. My palette knife the actual part used for spreading buttercream is about 2.5 inches but a similar size would work well also. – ▢Coloring Gels used: Americolor Deep Pink Electric Green, Avocado Green, Lemon Yellow – ▢Silicone Pastry Brush: Optional - used to create light texture on the buttercream – ▢Miscellaneous; Wax paper/parchment bench scraper/offset spatula for applying & smoothing buttercream, turntable (optional but helpful), cake cardboards- my cake is resting on it's own cake cardboard, and has another cake cardboard halfway up with supports beneath because of the double barrel (tall) cake design.
