How did Award-Winning Chocolate Cake earn the blue ribbon, the trophy, and the title of champion? Simple… by being the most intensely chocolate, perfectly sweet confection to come out of any oven! The cake itself is tender and rich, with a little added tang thanks to the addition of sour cream. Sour cream also adds a lovely contrast to the heavenly frosting spread all over the cake, bringing out the chocolate flavor and balancing out the luscious sweetness. Honestly, the question isn’t how Award-Winning Chocolate Cake won the award but rather what other awards we can give it!
