I am making bridal shower cupcakes.. was planning on using buttercream.. but she requested red velvet cake.. so I am using cc frosting. I usually just do cake.. so Im a little unsure of how to get such a flat surface on the cupcakes to get the decoration right.. any tips?

I'm going to throw out an idea that sounds like something I would do:

Level your cupcakes....then load up with frosting, getting the frosting as flat as you can.

Place a piece of waxed paper on the cupcake and use a fondant smoother to flatten. Leave the waxed paper on and chill the cupcake, then remove the paper.

Do the cc frosting and on top of that use fondant.

If you bake your cupcakes at 325 instead of the standard 350- they will rise much more level.

I bake at 325°, but my oven's not level so my cuppies are always wonky. I just add more icing to the shorter side and you can't tell.

Yep, those are fondant topped
