Galaxy theme: space-effect cake decoration
Metallic food colorings, edible glitter, and round molds for a galaxy-, planet-, or space-themed cake.
The galaxy effect on the icing
The galaxy effect is achieved by applying several food colorings (purple, blue, black) directly onto the still-wet icing without fully mixing them, then adding edible glitter or metallic coloring powder on top.
Shapes and finishes
A spherical silicone mold provides the base of a planet or full moon to assemble on the cake. Pearlescent powdered food colorings add a lustrous effect when dry-brushed onto the fondant.
Frequently asked questions
How can you prevent the colors from turning gray?
Apply the food colorings in small touches without working them for too long: overmixing blends the shades together instead of preserving the desired marbled effect.
Do you need a specific icing for this effect?
Buttercream or whipped ganache work well: their texture remains firm enough to keep the pattern in place after applying the food colorings.
Is glitter powder edible?
Edible powders and glitter sold for baking are formulated for consumption; check the food-grade label on the packaging before use.
