Small Batch Sour Cream Chocolate Cake with Sour Cream Chocolate Frosting

Pretty much the easiest best chocolate cake around. The chocolate cake is made in one bowl using sour cream and coffee to bring out chocolate flavor. The frosting is made of only chocolate, butter, and sour cream. If you have never had a frosting made of sour cream, you are missing out. It adds a tang and a richness that is unparalleled. And unlike frostings made with powdered sugar, it is the perfect balance of sweet and rich. I also paired the recipe down so that it is just made in an 8x8 inch pan instead of 2 or 3 round cake pans. It’s perfect for weeknight baking. Seriously, go make this sour cream chocolate cake with sour cream frosting!
