Honestly, ounce for ounce, mitts are warmer than gloves. Also try to warm your hands up in the lodge before you put them in the gloves and go outside. The glove insulates heat your hand gives off. If your hand isn't giving off heat, then it doesn't matter what glove you have on. Also, running the gloves on a glove warmer or sticking a hand warmer in them before you go out can help too.
