I'm doing Sesame Street cupcakes and will be making hair for Elmo and Cookie. I don't want to use my normal crusting buttercream because the "hair" would be all hard and crunchy.
Some suggested SMBC. Is that what I need to use? I've never worked with it before. What is a good recipe to use? And can I make it ahead of time?
Try the marshmallow buttercream recipe on this website. It's my favorite!
It is made with marshmallow fluff and is delicious and easy! It does not crust.
i have used the hair/grass tip with my smbc and it works just fine
but if you should make sure you heat your egg whites to 160 to make sure they are food safe since it sounds like you are baking for kids (i check the temp every time i make it to be sure).
there are some great recipes for smbc here on cake central.
smbc can be softer than most crusting buttter creams so you may want to alternate bags if you have warm hands in order to keep the hair well defined.
