Chocolate Peanut Butter Marble Cake Recipe

Preheat oven to 350 degrees F (175 degrees C). With a non-stick cooking spray coat a 13X9X2 inch baking pan. Dust with flour and set aside.

In a small bowl stir together the cocoa confectioners' sugar butter and 2 tablespoons hot water until smooth and set aside.

In microwavable bowl place peanut butter chips and shortening. Microwave on high for 1 minute or until chips are melted and smooth when stirred.

In large bowl combine cake mix brown sugar 1-1/4 cups water eggs and reserved melted peanut butter mixture; beat on low speed of electric mixer until moistened. Increase speed to medium beat 2 minutes until smooth. Remove 1-1/2 cups of the batter and add it to the reserved cocoa mixture; blend well.

Pour the peanut butter flavored batter into the prepared pan. Drop spoonfuls of the chocolate batter on top. Swirl with a knife or spatula for a marbled effect.

Bake at 350 degree F (175 degrees C) for 40 to 45 minutes or until a wooden toothpick inserted in the center comes out clean. Cool and frost as desired.
