I have searched hi and lo and cannot figure out the tip used to create the swirl on the standard size cupcakes. Can someone please tell me what it is and where online I can buy one?

let me clarify more - I already have the 1M, I'm looking for the one to make a smooth swirl

Sorry but I'm not sure what you mean. To clarify can you look at my photos and the mickey cake has some cupcakes with it.....do you mean a swirl like that? If so I can help, if not I may have another idea....lol sorry I'm on cold meds, work with me

I use a Wilton 2A for a smooth 1M swirl. HTH.

if you don't want to buy a specific tip for it then you can use a coupler with out a tip on it. If it's a wilton one with a slot in the side then just use a piece of tape over the slit to close it up.

Ok since I'm still not sure what you mean here are two methods I use:
1st if I want to pipe a tight smooth swirl I use a wilton #10.
2nd is when I want to have the look of large dollops....I use a disposable piping bag, cut the tip off but start small and pipe, if its too small cut more until you're satisfied with the size swirl you're creating. I sometimes use a coupler as mentioned by PP but like having control over how large I want my swirl so usually just cut the tip of the piping bags . You can also do this with a zip loc baggie.
HTH as mentioned I'm on cold meds and sslo 5 months pregnant so my kind is pretty much shot lol
