2011's Most Over-The-Top Fast Foods Slideshow

Plain old stuffed crust? That's so last decade — at least according to Domino's Pizza. Earlier this year, the chain rolled out a line of "Stuffed Cheesy Bread" that's full of "cheese, cheese, and more cheese." In fact, the breads — which come in Spinach and Feta, Bacon and Jalapeño, and plain Cheese — contain as much cheese as an entire medium pizza.

A bowl can hardly contain "layers of your favorites" without including bacon. Or so was the logic at KFC, which added bacon as a limited-time topping to the chain's line of "Famous Bowls." How did they do it? Well, they took a 680-calorie combo of mashed potatoes, corn, Popcorn Chicken, gravy, and cheese — then added bacon.

Fast-food excess is hardly reserved for food alone. Take Starbucks' Trenta-sized cups, the veritable Big Gulps of coffee consumption, which each contain 31 ounces of caffeinated brew to pour down your gullet. And if caffeine-induced twitching isn't enough of a health risk, consumers should be advised to pace themselves: The cups are actually larger than the typical human stomach.

What's more horrifying than an ice cream sundae that features vanilla soft serve, maple syrup, and bacon bits? An entire menu of creations based on the same bacon-centric principle. Denny's, however, has gone there: The chain's "Baconalia!" menu included that cringeworthy sundae, along with a triple-decker BLT, Bacon Meatloaf, and Bacon Flapjacks.

If fast food has taught us one thing, it is this: Any food item can be stuffed inside any other. Burger King's Stuffed Steakhouse Burger, introduced earlier this year, is a prime example. Not content to simply put cheese atop a burger patty, the chain stuffed bits of Cheddar and jalapeño inside the beef, for "an experience you can see and taste in every bite."

Pizza Hut's "epic-size" repast offers up two medium pizzas, eight wings, and five breadsticks — in one convenient box! For the low prize of $20, ravenous diners might be tempted to scarf down the entire thing themselves, but please, make this one a family affair: The items in a single box are estimated to contain around 5,000 calories.

If you're craving a pancake and sausage breakfast, but just can't find the time, Dunkin' Donuts discovered a solution in 2011. An order of the chain's Sausage Pancake Bites offered diners three nuggets of flapjack dough that each enclosed a sausage link. A trio of nuggets also managed to enclose 20 grams of fat, more than most doughnuts.

Think outside the bun — and the conventional taco shell. In an apparent bid to include as much junk as possible in a single meal, Taco Bell used California and Ohio residents as guinea pigs to test shells made entirely of Doritos' nacho-flavored chips. The cheesy delicacy might be introduced nationwide next year, when, presumably, the chain will also swap burrito wraps for potato chips.

Why eat one sandwich, when you can eat three? The KFC Double Down may have replaced a burger bun with fried chicken, but this year, Friendly's managed to outdo even that monstrosity. They swapped out a cheeseburger's bread with two entire grilled cheese sandwiches. This gastronomical innovation, not surprisingly, is also a caloric nightmare: 1,500 per sandwich(es). Even that doesn't seem to be helping the company — the 76-year-old family-dining brand filed for Chapter 11 bankruptcy protection on Oct. 5.
