Chocolate-Peanut Butter Cake


This showstopper of a cake has your name written all over it. The recipe counts on baking soda rather than the typical addition of baking powder to help it rise. Baking soda can't work on its own, so it needs the help of acidic liquids—including buttermilk and brewed coffee—to create a reaction that results in a light, fluffy, risen cake. The cake recipe calls for a short list of ingredients—including shortening, all-purpose flower, cocoa, baking soda, salt, brown sugar, granulated sugar, butter, eggs, baking squares, vanilla extract, buttermilk, and coffee—plus a few extra ingredients for the peanut butter frosting too. (Don't skimp on the frosting. It's delicious.) Once your cake is baked and frosted, garnish it with peanut butter cream-filled sandwich cookies, which you can use to decorate as you see fit. This Chocolate-Peanut Butter Cake is a deliciously decadent dessert, and it'll satisfy your sweet tooth in no time at all.

  1. Preheat oven to 350°F. Grease (with shortening) and lightly flour a 13- x 9-inch pan.

Beat at low speed just until blended after each addition. Beat in coffee until blended. Pour batter into prepared pan.
