I need some cupcake help please!?

Don't fill them with ice cream, they would get really messy, I would leave them as they are, or fill with some type of frosting or buttercream. Make a sheet cake, any size you would like and then take a stick, like a kabob stick (realllly big toothpick) and stick it into the cake. Then push the cupcakes through the center and stack them like that. It would be differant and cute!
