When you make RKT blocks, do you frost them & cover them w/fondant or are they sticky enough to where you can just add the fondant over it w/o frosting or any other form of "glue"? I am making a cake for my Best Friend's Son, he is turning 4 & he LOVES blocks. Thank you so much in advance for all of your help

You could probably cover them with just fondant (you may have to brush the RKT with water first), but any bumps in the RKT will show. Frosting them first with give you a smoother surface to apply the fondant.

I would frost them first to give the blocks a smoother surface.
