Instructions

- Allow mixture to cool to room temperature.
- Whip remaining cream to soft peaks and fold in.

3. Assemble the Domes

Tips for Perfect Santa Dome Cakes
Keep everything cold
Cold mousse + frozen filling + chilled glaze = smooth professional results.
Don’t rush the chilling time
If domes aren’t fully set, they won’t glaze properly.
Choose high-quality white chocolate
It affects both the mousse and the glaze texture.
Use gel food coloring
Liquid dyes can water down the glaze.
Make ahead like a pro
- Freeze domes up to 48 hours
- Glaze up to 12 hours before serving
- Decorate just before serving for the cleanest look
Recipe Variations
Peppermint Santa Domes
Replace vanilla with peppermint extract for a candy-cane flavor.
