The Bingo Birthday Cake was a fruit cake but you could use a sponge cake. I covered the cake with marzipan and then fondant. I drew a grid using a edible ink pen and a ruler and then went over it with coloured icing. Then I rolled balls of icing for the bingo balls and piped numbers on then. As well as piping numbers on the bingo card and wrote happy birthday in coloured icing.
I finished the edging around the cake with coloured icing again and the cake was finished. I also cut small round discs out for the counters and arranged them on the cake. Everyone was pleased with result.
You have done a great job on that cake. It looks brilliant.
