I want to try MMF or rolled buttercream but all I have is a 225 watt hand mixer. Can it be done?

yes, knead the sugar in like you would flour into hand-made bread dough.

(Builds strong arms!)

Sure you can make MMF w/out a stand mixer...
That's what I always do.. I use my hand to knead, but before that I use a wooden spoon to mix the hot Marchmallow into the powdered sugar at first..

Sure can. I don't even have a hand mixer at the moment. So that's all I can do is make things by hand. It's a little messier, but works out fine. I just mix it with a wooden spoon until it's too stiff, and then go at it like bread dough.

Just make sure you remember to take off your rings and/or bracelets! I forgot one time ... won't ever forget again!

you can prolly do in in a food processor with the dough blade.
