when making oatmeal no-bake cookies, mine always turn out too soft?

almost running & they don't dry into a firm cookie but more like a chewy chocolate mess. what is the problem here? Am I not cooking the ingredients long enough? Mt recipe says 1-3 minutes ~ how do I know when enough time has passed?

You're not cooking them long enough. Get a timer. Your microwave should have one on it. Get it set to 3 minutes....and then as soon as your ingredients start to boil (and I mean really do boil), hit the timer to start. Then once the timer goes off, it should be safe to turn the heat off. Just be sure to stir them the entire time their cooking or else you'll end up with a burnt gooey mess.
