Chocolate Sheet Cake

Well, I'd just love to take credit for this mouth melting morsel of a recipe, but I have to give all the credit for added poundage to my ever growing hips to Pioneer Woman. Check out her "Best Chocolate Sheet Cake Ever." I made it and ate it and now I'm dieting again! The pecans are what sold me. I'm nutty you know? Kaedell, are you keeping track of the people in our family and whether or not they're getting their recipes on here? Get your whip out - I'm crowning you "Chief In Charge." Also I love the "Lazy Cooking category" and I suppose Seth will dominate this area. Here's the how to for the cake:
