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.

How To Make homemade chocolate cake with peanut butter frosting

  • Greasing a baking dish.
    Preheat oven to 300 degrees. Grease the bottom and sides of a 13x9 inch baking pan.
  • Dry ingredients mixed together in a bowl.
    Mix the flour sugar, cocoa, salt, baking powder, and baking soda together in a large bowl.
  • Beating eggs with a mixer.
    Beat the eggs with an electric mixer until they are bright yellow and slightly thick.
  • Oil, coffee, and vanilla to the eggs.
    Add the oil, coffee, and vanilla to the eggs. Mix until well incorporated.
  • Adding some of the dry ingredients to the bowl.
    Add the flour to the mix, alternating with the buttermilk, mixing after each addition until just incorporated.

  • All ingredients incorporated.

    Pour the batter into the prepared baking pan. I always hold the pan up a few inches from the counter and let it fall to get rid of air bubbles in the batter.
