Chocolate Pecan Cake

"Pecan frosting paired with chocolate cake? That’s the cat’s meow right there! The frosting is on the sweeter side thanks to the addition of brown sugar, but it truly is delicious. I had initially planned on topping this cake with a layer of freshly whipped cream, but I had extra pecan frosting left. I called an audible and just skipped the whipped cream topping in favor of more pecan frosting. (However, I do think frosting just the sides of this cake and then topping it with whipped cream would still be quite tasty!)"
