This one is a yummy, creamy fondant cake, which has a design resembling polka dots. I am sure by now you have got the fondant cake decorating supplies handy. To decorate this cake, cover this cake first with slim layer of butter cream frosting. Then cover the cake with a layer of fondant. Taking a different color of fondant from the one which you used to apply the first layer, cut circles of various sizes from that. Further, butter cream can again be used like a glue to stick the fondant circles.
