Trapped in the Dessert!

You're lost in a massive building that's completely new to you. It's your first day of work, and of course you've gotten yourself lost and can't find the HR lady's office for your meeting. You walk through a door and find a very tight hallway with four doors along the left side and nothing else. The door you just came through clangs closed loudly, and your attempts to reopen it are fruitless. You decide to venture to the first door on the left. As you open it, an avalanche of something hard starts falling on your head. You stumble back and realize that you're being surrounded by a mountain of peanut butter cups! You go to the next door... a mountain of doughnuts! The third reveals a mountain of brownies, and the fourth a mountain of gooey chocolate chip cookies! You decide that someone has infinitely outdone the old secret candy drawer! Above each mountain is a faint light from what seems to be an open door on the opposite side of these rooms full of sweets. Which room will you attempt to traverse? HR is expecting you, after all.
