Is there another way to put filling in cupcakes than using the Bismarck tip 230? I don't have this tip!!
I just use a plain old circle tip (not sure of the proper term)... think it's around a size 12? large enough to let the filling come out in a relatively short time, not too big so it ruins the top of the cupcake. push it in squeeze and remove. works great!
You can use any tip that will allow the filling to come out without squeezing too hard. I have used a #5 and it worked good.
I have a hard time judging how much filling I put in a cupcake when I use a tip. I usually end up erring on the side of safety, and end up with not enough filling.
My favorite way of filling cupcakes is to cut a cone out of the top, put filling into the hole, slice off part of the cone, and put the top back on. I cover the entire surface with icing, so no one notices that the cupcake has been cut.
