5. Let the cake cool completely before cutting and shaping

2. Carve & Frost the Cake

1. Once cooled, cut the cake into the shape of a mermaid tail. Use a template or freehand the shape

Expert Tips & Tricks

Best Practices

• Chill the cake before carving to make shaping easier
• Use a small offset spatula to apply buttercream smoothly

Common Mistakes

• Don’t skip the crumb coat, or the buttercream may not adhere properly
• Make sure the fondant scales slightly overlap for a more natural look

Time-Saving Tips

• Bake the cake a day in advance and refrigerate before carving
• Use pre-colored fondant to save time on dyeing
• Pipe buttercream details instead of fondant scales for a quicker decoration method
