To apply the whiskers, I use a chopstick. I dip my chopstick into a little bit of water, paint a tiny amount of water onto the white cheek where I will add my whisker, then I put the whisker in place, holding it there for 30 seconds. I then gently press the part of the whisker that reaches past the cheek into the buttercream to help it stick. Do the same with the remaining three whiskers, two for each cheek. 10 Finally, add the ears! Looking down at the top of the cake, I find the halfway mark and place the ears just in front of that mark, set apart from each other. Using your piping bag filled with buttercream, pipe short spurts of fur along the edges and backs of the sugarpaste ears.
