For my daughter's first birthday I wanted to make her cake so I have been taking classes. I think I should be ok on the decorations part but I REALLY wanted to do a giant cupcake on top of another cake. What is the best way to do this?? do I need to put something under it because I really don't want it to sink!! Help.

By the way I am going to give the cady shell a try so if that changes anything let me know!

Thank you so much~!

You probably should put a cake board underneath the cucpcake and dowel or use some supports on the bottom layer. It would be the same procedure as stacking a cake. You can probably search "Stacking" here on CC for some good tutorials or posts.

You will need to use dowels or straws in the base cake and your cupcake cake needs to be on a cardboard cake board. Watch some of the tutorials on youtube "how to stack a cake" ...this is how I learned to properly stack a cake. I am a visual learner and do much better 'seeing' what I'm trying to learn.

I did a topsy cake with the giant cupcake on top for my DD's b-day a few years back (in my pics), and was concentrating so hard on getting everything right, that I forgot to put the supports in!
I got the cupcake all positioned and stepped back to look, and noticed that the cupcake was sinking into the cake already! Because it was a topsy/turvy, it literally cracked around the edge of the bottom tier, and ended up being a disaster!
After the picture was taken, it continued to fall apart, and ultimately, ended up tying a ribbon around it just to hold it together!
