This one is for the impatient soul who needs a slice right this second. Take a large, flat metal baking sheet and run it under cold tap water for a minute. Dry it off completely.

Now you have a warm-brownie-on-the-inside, cool-on-the-outside situation. It's oddly perfect. You get that fresh-baked taste without the risk of burning your tongue or making a crumbly mess.
