I have an old recipe binder that I started years ago when I was bitten by the baking bug. The pages are yellowed now and some of the recipes have broken free from the binder and are tucked in there as best they can be. That's where this recipe has lived for many years. I can't tell you where it originated from, but I can tell you that my sister in law gave it to me. In April 2008 this chocolate cake made its debut as the first recipe I ever put on my blog. It's very special to me and brings back memories of birthday parties and special occasions with my kids.

Wow! This is an old-fashioned recipe with simple ingredients that's classic and delicious. The chocolate cake is super moist and tender thanks to the buttermilk. Coffee brings out the chocolate flavor and adds a lot of richness. The peanut butter frosting is super easy to make and the perfect topping to this wonderful cake. This recipe is simple enough for every day, but fancy enough for a special occasion. Trust us, there won't be a crumb left.
