I've been wanting to try brush embroidery for the first time, and decided to do so for a V-Day cake I'm making for DH and myself.
The recipe I chose has a marshmallow-like frosting, and looks fluffy like 7-minute frosting in the picture. It has no butter in it- just egg whites, sugar, water, corn syrup, and flavoring.
Can you do brush embroidery on a non-buttercream/non-fondant surface, or would it be too soft?

I'd like to know too!
I have only done brushed embroidery on fondant or a crusting buttercream.
You could always spread some of the icing on some wax paper and then try to do your brush embroidery on it to see if it will work.
I think your icing would be too soft. Our Wilton Instructor taught brush embroidery on fondant.
As a Wilton instructor, I also have only taught brush embroidery on fondant, mmf, or really crusted buttercream. If the icing crusts, you can do it, but you must use a very light hand.
