For Decoration

Instructions

Prepare the Sponge Cake Base
Preheat your oven and line a baking pan with parchment paper. Whisk together flour, baking powder, and salt. In a separate bowl, beat eggs and sugar until pale and fluffy. Gently fold in melted butter, milk, and vanilla, then incorporate dry ingredients until smooth.
Bake and Cool
Pour the batter into the prepared pan and bake until lightly golden and springy to the touch. Allow the cake to cool completely before cutting out small rounds that will fit the base of your dome molds.
Make the Strawberry Filling
Cook chopped strawberries with sugar and lemon juice until juicy. Stir in cornstarch slurry and simmer until thickened. Cool completely before use.
Prepare the Vanilla Mousse
Bloom gelatin according to package instructions. Whip cream to soft peaks. In another bowl, beat cream cheese or mascarpone with powdered sugar and vanilla. Gently fold in whipped cream and melted gelatin until smooth and airy.
Assemble the Domes
Spoon vanilla mousse into silicone dome molds, pushing some up the sides. Add a spoonful of strawberry filling in the center, then cover with more mousse. Press a sponge cake round on top to seal.
Freeze Until Firm
Freeze the assembled domes for several hours or overnight until completely firm.
Decorate the Santa Domes
Unmold frozen domes and glaze with red mirror glaze. Use white chocolate details for Santa’s beard and trim. Add strawberry or fondant accents for the nose and hat pom-pom.
Serve and Enjoy
Allow the cakes to thaw slightly before serving for the perfect mousse texture.

Tips for Perfect Santa Dome Cakes

Always freeze domes fully before glazing for a smooth finish
Use silicone molds for easy release
