I’ve been asked to make a cake with this type of text, the cake is covered in fondant. I don’t know how this texture was achieved.. I’m thinking maybe it’s gold dust but it’s probably mixed with something other than alcohol/water. Anyone have any idea how to achieve this texture? 

i could recreate it but idk how they did it -- it has craters and dots so i'd poke on both sides i guess -- i'd have to experiment with what product would be poke-able though -- it actually looks like foil to me -- but it could be done with some kind of texture mat? idk but someone smart will be along to help -- certainly appears hand done -- idk

You could do it as a lay-on or directly on the fondant.

As a lay-on, I'd cut out the numbers, place them on some medium stiff foam, use a tool on the backside to raise the edges on the front, then use the same tool on the front to create the dimples and then paint them.

Directly on the fondant I'd outline the numbers with a scribe, use a tool to make the dimples, pipe small royal icing dots around each number, and then paint them with edible gold dust.

It looks like they were cut from some type of foil.  You could cut numbers from fondant, take some type of imbrossing tool to make the texture and spray gold color with Wilton color mist spray.

The number shown appears to have been done directly onto the side of the cake.  The dimples were probably made using a couple of different sizes small ball tools or round tipped sugar shaper, then painted with gold dust mixed with cocoa butter or vodka.  It would probably be easier, and in my opinion, more beautiful, to cut the numbers from fondant and dimple them.  Allow the numbers to set up a little bit, then color them with the gold of your choice.  If done this way, Wilton gold spray would be ideal and it is about the same color as shown in the picture.  It also has the big plus of being edible.  Once dry, apply the numbers to the cake.

So many ideas. Thank you! I think I can achieve it now :)

Good luck, Moonstone.lady!  You got this!
