So im making a Darth Vadar cake for this weekend and it going to dark blue with silver fondant stars. Is it possible to add sparkle to the buttercream?
Can I put luster dust in it?
Any thought would be fantastic!

Generally you would have the dusts after. I'm not sure they have the same effectiveness when mixed in with buttercream.

take a spoonful of icing and mix in a little sparkle and do a test.

I always heard your best to add it afterwards, putting it in loses the shine.

Definately add it on after. I have tried mixing it in with my icings both buttercream and fondant and it just either gets lost in the mix or doesn't give you the total effect that you are wanting. You could also use Disco dust to add a sparkle to it.

Thanks for the advice everyone. I knew it was a long shot but I thought I would ask.
I would love to use disco dust by my local stores don't carry it. The next closest stores are an hour away (those are just craft stores) and the closest big cake store is about 2 hours from here.

I LOVE when I get to go to the cake store. Its like heaven...heaven that cost me a lot of money.

Well I have one more week to figure it out cause the birthday party got postponed. Looks like their cakes are going in the freezer since I just finished baking an hour before they called.

You have plenty of time to order from many different online stores- I have used- Global, Oasis, Sweetwise, I usually recieve my order within 2 days- and thats with the regular shipping!

Really? Ill take a look. Last time I wanted to order just one thing the shipping was far more than the product. I'm in Canada so my order might take longer to get here depending on who i order from

Golda's kitchen has lots of stuff - they are in Ontario and I order from them all the time - great service! You may also be able to pick up what you need at your local hobby store or Michael's. Have fun!

Thanks cakesrock. That is exactly who I ordered from and it showed up in two days.
I live about 2 hours from Goldas. We have bulk barns and micheals a little closer but Goldas is the closest one stop shopping store. Great place, I could spend all day in there.
