  • Sounds interesting, bet hubby would love it. Wonder how it would taste with some chocolate added to the icing. - 1/21/11

  • I just ran a VERY similar recipe through the calculator using real butter instead of oil, KEITHGABLEs calculation appears to be correct. Please be sure to note that it's 24 servings which in an 11X17 cooking sheet is approximately 2.75 X 2.85 inch piece. Small but incredibly rich and satisfying :) - 6/24/10

  • I considered making this but it seemed it would be higher in fat and calories than shown. I plugged in the ingred. substituting applesauce for oil, reducing sugar and butter, and skim milk rather than buttermilk and doing that gave me a higher calorie and fat content; the info above is incorrect. - 10/2/07
