I found this while hunting for recipes that call for buttermilk, in an attempt to use some up before the Sell-By Date of No Return, and it's amaaaazing. If you like the chocolate & peanut butter combo, definitely try it. It tastes like a Reese's cup in cake form! :D It's quite rich, and absolutely perfect with a glass of milk. Sadly there wasn't a chance to take pictures before it was devoured, but the recipe is under the cut.
Recipe from

Peanut Butter Fudge Cake
For cake:
* 2 cups all-purpose flour
* 2 cups white sugar
* 1 teaspoon baking soda
* 1 cup butter
* 1/2 cup unsweetened cocoa powder
* 1 cup buttermilk
* 2 eggs, beaten
* 1 teaspoon vanilla extract
* 1 1/2 cups creamy peanut butter
For frosting:
* 1/2 cup butter
* 1/4 cup unsweetened cocoa powder
* 1/3 cup buttermilk
* 4 cups sifted confectioners' sugar
* 1 teaspoon vanilla extract
Directions
1. Combine flour, white sugar, and baking soda in a large mixing bowl; set aside.
2. Melt 1 cup butter or margarine in a heavy saucepan; stir in 1/2 cup cocoa. Stir in buttermilk, and eggs until well blended. Cook over medium heat, stirring constantly, until mixture boils. Remove from heat. Mix into flour mixture, stirring until smooth. Stir in 1 teaspoon vanilla. Pour batter into a greased and floured 13 x 9 inch baking pan.
3. Bake at 350 degrees F (175 degrees C) for 20 to 25 minutes, or until an inserted wooden pick comes out clean. Cool 10 minutes on a wire rack. Carefully spread peanut butter over warm cake. Cool completely.
4. To Make Frosting: Combine 1/2 cup butter or margarine, 1/4 cup cocoa, and buttermilk in a small sauce pan. Bring to a boil over medium heat, stirring constantly. Pour over confectioners' sugar, stirring until smooth. Stir in 1 teaspoon vanilla. Spread chocolate frosting over peanut butter on cake. Cut into squares.
I forgot to sift the confectioners' sugar and add the vanilla to the frosting (baking while watching television = not a great idea haha) but it that didn't seem to affect anything.
