My brother-in-law is very into working out and weightlifting so I wanted to make a special and fun cake for his 30th birthday. We came up with a Dumbell Weightlifting Birthday Cake and put the # 30 on each side.
I used 2 spring form pans and 2 smaller round pans for make the weights. I used a rolling pin covered in aluminum foil and the bar. You have to cut out the circles for the bar/rolling pin before inserting or the cake with fall apart. I just used store bought frosting and it came out great. The only thing I would have done differently was I should have made the background a different color then the foil so it would have stood out more but hey my brother-in-law and everyone loved it!
