Base Colour

• Cover the cake completely in one solid colour of buttercream (this will be your stripe background).
• Smooth with a bench scraper until clean and even.
• Chill the cake until firm (important as this keeps the stripes sharp).

Create the Grooves

• Hold the striped cake comb against the chilled cake.
• Spin the turntable while gently pressing the comb into the frosting.
• This scrapes away evenly spaced stripes, leaving “grooves” for your second colour.
• Scrape until you see clear grooves without smearing. Chill again.

Fill in the Stripes

• Tint your second batch of buttercream the contrasting colour.
• Put it in a piping bag and pipe buttercream directly into the grooves.
• Don’t worry about neatness you’ll smooth it out later.

Smooth Everything

• Use a bench scraper to remove excess frosting, revealing sharp stripes.
• You may need to add more colour and scrape again until it’s perfect.
