I don't have a stand mixer, only a hand mixer and a food processor and was wondering if anyone made buttercream in their food processors?
Would it be too fast?
I don't know how it would work in a food processor. The hand mixer is fine for small batches I would think. If you would be making a SMBC, the food processor is not the equipment you would want to use.
I have not seen in any of the cooking shows where a pastry chef would use a food processor in making the frosting. Batters and doughs, yes but not frosting or icing.
If you are doing an American buttercream (butter shortening, powder sugar, flavoring) it works quite well and gives you air bubble-free frosting. Just don't overload it (you might have to 1/2 your recipe) and don't run it to long because the motor gets hot. I used to use it all the time.
Electric frosting (uses food processor):
(Not an American b/c.)
Before I had a stand mixer, I made my American b/c's with a hand mixer. As has been said, you just can't make huge batches...
