Silver is an elegant color to use in decorating baked goods for weddings, holidays or other special occasions. You can make your own silver icing or fondant from regular white buttercream frosting or fondant, black food coloring and silver luster dust. Luster dust is a fine, edible powder that can be brushed or painted onto icing, fondant and candy to make them shine. It can be purchased at most cake-decorating specialty stores.
Mix a few drops of black food coloring into a batch of white buttercream icing until the icing becomes gray.
Apply icing to the baked good(s) you are decorating.
Dip a soft artist’s brush into dry silver luster dust. Gently shake or flick the brush to sprinkle the luster dust onto the icing. Repeat until the desired effect is achieved.
Put on disposable kitchen gloves. Add a few drops of black food coloring to white fondant. Knead the dough with your hands until the desired hue of gray is achieved.
Roll the fondant out, and apply it to a cake. If you want to make silver accents, mold them out of the fondant, but do not apply them to the cake.
Pour a small amount (about 1/8 cup) of lemon juice, vodka or clear vanilla into a small bowl. Dab the tip of the artist's brush into the luster dust, and add the luster dust to the bowl of liquid to create an inklike consistency. Paint the solution onto the cake or fondant accents with a soft artist’s brush. Apply the metallic accents to the cake after they have finished drying.
If the fondant becomes too sticky while you knead it, add powdered sugar.
