To successfully put a cake topper on buttercream frosting, apply it either at the last minute or after the buttercream has formed a slight crust.
Here's a breakdown of the process and considerations:
Best Timing: Crust or Last Minute
- Crusted Buttercream: Allowing the buttercream to develop a slight crust before applying the topper helps prevent it from sinking into the frosting or causing smearing. The crust provides a more stable base.
- Last-Minute Application: If you can't wait for a crust to form, applying the topper as close to serving time as possible is the next best option. This minimizes the time the topper has to interact with the buttercream's moisture.
Applying Wafer Paper Toppers
If your topper is made of wafer paper, follow these additional tips:
- Moisture Sensitivity: Wafer paper is very sensitive to moisture and can curl or warp if it gets too wet.
- Slightly Moisten (If Needed): In some cases, a very light mist of water on the back of the wafer paper or the surface of the buttercream (again, a very light mist) may help it adhere. Avoid over-wetting under any circumstances.
- Gentle Placement: Carefully place the topper onto the buttercream, avoiding excessive pressure.
Tips for Different Topper Materials
While the timing is consistent for most toppers, material affects other elements:
| Topper Material | Considerations |
|---|---|
| Wafer Paper | Extremely moisture-sensitive; apply at the last minute or onto crusted buttercream. Use moisture sparingly, if at all. |
| Fondant | More durable; can be applied slightly earlier. |
| Plastic/Acrylic | Can be applied at any point; won't be affected by moisture. Make sure it is food safe. |
| Chocolate/Candy Melts | Best applied once buttercream is firm to prevent melting. |
Troubleshooting
- Topper Sinking: If your topper starts to sink, try gently lifting it and placing a small piece of parchment paper underneath to provide support.
- Color Bleeding: If your topper's colors are bleeding into the buttercream, you may have used too much moisture. Blot the excess moisture with a clean paper towel.
By considering the type of topper and timing your application carefully, you can ensure your cake topper looks its best on your buttercream-frosted cake.
