Okay, I am making a playground cake. I have the design figured out. I am basically doing a slide on the top and on the sides making it look like a castle. However, I need something I can use for sand that people can eat. Any suggestions?

how about finely crushed graham cracker?

I use graham crackers, but I've also heard of people using brown sugar or crushed 'Nilla wafers. Sounds like a cute cake idea

or crushed nilla wafers....

Never tried the vanilla wafers...good suggestion. I use brown sugar that I whisk to fluff it. Works great every time. I'll have to remember the vanilla wafers...

I have used vanilla wafers as sand. I was afraid that brown sugar would make it too sweet and would clump. I used my food processor to crush the wafers until they were "sandy" then sprinkled them heavily onto a freshly iced cake. They did not alter the "sweetness" of the cake and everyone raved about the cake. You can see it in My Photos.

On my sea shell cakes (photos in gallery) I used raw sugar for sand and I really like the look of it. I have also used brown sugar.

Looks like 'nilla wafers are the winner!

Nilla wafers sound good. I've used vanilla creme cookies..pulsed them in the food processor, turned out well.
