Blot Blot Blot
grab several clean white absorbent cloths. (Don't use paper towel the lint will just make a bigger mess) keep dabbing the spot with the cloths. If you have a hair brush use it to tap the towel into the fibers. just bang the bristles of the brush on the couch with a clean white towel between. never wipe, rub or scrub fabric. it will wear and distort the fibers leaving a permanent discoloration.
If you feel you need to get some friction, just wrap the cloth around your fingers or thumb and push down on one spot and then rotate your thumb then lift. don't go back and forth.
The pounding on the towel with a brush should remove most of the stain and the moisture.
if you have a vacuum that you can reverse the flow by putting the hose on the other end, use it as a blower to dry and fluff the fabric so it doesn't get stiff. Don't use a hair drier as it is too hot and will cook the stain in and also wreck the fabric. Don't use any cleaners or detergents without a specific recommendation from the manufacturer of the furniture. Detergents will leave invisible residue behind that will act like a magnet for dirt and in a month or so you will have an icky unidentifiable stain on the couch and it will haunt you for the rest of your days. you will have to buy throw cushions, tonnes of throw cushions at $30 each.
Because you bought a microfibre suede couch I am assuming you are a single male with no children. If you have a nasty stain on your couch none of your dates will want to sit on your couch with you so be careful how you deal with it.
Advice: Next time buy leather even cheap leather will outlast any fabric couch and they are so easy to clean and or repair.
BTW, was it a chocolate frosty or the new vanilla frosty?
