Well you could do my "mistake" method.
Flood your background, then go back and make dots with a slightly thicker consistency icing while still wet.
If you look at the pics in my gallery it's the onsie with the pink dots!
Because the dot icing was a tad bit thicker and heavier, it sank and left "dimples".
Hope this helps

Rose - that is so cool! I'm not sure I understand, though...
You flooded the cookie as normal, them used a slightly thicker consistency to do dots right away, right? And it left indentations? WOW! I've got to try that!
lego sure would have been quick-i used the small end of my fondant ball tool for my multi-coloured ones oh and fondant definately 
I haven't done Golf Ball COOKIES... but once I flooded a COOKIE and then put on some dots while the icing was still wet so that it will go flat... you know that nice polka dot effect... but I used a thicker consistency for the dots and the icing sunk (sp?) causing dimples on my COOKIES... I wasn't thrilled with the result (that time I wanted flat COOKIES) but thought it would serve for a different effect...
so you might try and see if it works
