Please help! What medium to I use for the most sparking cake... Americolor pearl, or what else would make the cake glisten and sparke more. Would like to use the airbrush with it. Thanks for your help ASAP.

Is this a white cake? What are you trying to achieve?.. Fondant or buttercream?

The cake will be buttercream. I just want it to glisten and sparkle when light is on it. I have the spray pearl but it does not shine quite as much as I would like. Thank you Edna. I love your work. You are my inspiration on many cakes. Thanks again.

If you have an airbrush you can use the airbrush pearlized color. If you dont, there is a company that sells a can of pearl spray that looks almost like an airbrush.
Dust wont work on buttercream, only over fondant.
Hope this helps, thanks so much for the complements!

i've used white sanding sugar on buttercream and it sparkled beatifully. i just pressed it into the buttercream lightly.

I'd use sanding sugar with those edible glittery things.

Thanks everyone.

When I used to use a crusting BC, I would dust it with luster...worked nicely. I used a big poofy blush brush (new of course)

I've sprinkled edible white glitter on cakes and it looks nice and sparkly.

I think they have white luster dust? It would be shinier than pearl, or you could mix the two. Actually, I have added nusilver luster dust (powder) to pearl dust (powder) mixed with alcohol and sprayed it on with the airbrush and it was nice and sparkly! I don't like the pre-made silver airbrush spray as much, it's too wet, using the alcohol makes it dry more quickly and doesn't affect the BC as much.

Also, you can get a shaker of this: http://www.pastrychef.com/RAINBOW-SPARKLES_p_1550.html

I love this stuff...very prismatic, rainbowish and catches the light like diamonds.

Wilton makes a product I think you are looking for. It is called Cake Sparkles. I found it in the cupcake section. They are like small flakes of glistening sugar. Not as fine as a luster dust. More like mini mirror flakes or like mica. Beautiful and can look very nice. I used the navy color for a solar system cake to add sparkle to the cake. It is more sparkle than luster.

Be careful with the timing, however. I used the Wilton cake sparkles for a snowflake cake...put it on in the morning before work and by the time the office Christmas party started 4 hours later they had dissolved into the buttercream and yes, it was refrigerated.
