Full power first, check that the aircraft is pointing in a sane direction and is still flying second, then flaps (to 20 in my case) as the third action. So for a second or three I am going around at full power - there's no way I'm going to faff around with the flaps before I've got the power on.
Instructor didn't complain when I did exactly that on a currency check ride the other day.
Yeah, so er...we agree then.
