Bake for 25 to 30 minutes. Begin making the icing when cake is done. In a small bowl, melt the butter, cocoa powder and Dr. Pepper in the microwave. Once the butter is melted and the mixture slightly bubbles, pour in the powdered sugar and little at a time, whisking vigorously by hand. When all the powdered
