Leave it to the chubby guy (me) to find something like this...
Hostess just came out with a new "party size" Twinkie baking kit. And it lets you bake a giant, two-pound Twinkie that should serve at least eight people... Unless it's my house and then it serves one or two!
If you're interested, the kit is on sale at Walmart for $15. And it even comes with the custom baking pan you need to make it.
