Expert Tips

  • Trademarks referred to herein are the properties of their respective owners.
  • Cake is best served the same day, as cookie topping will begin to soften after a day.
  • For best success with this recipe, be sure to use a 15x10-inch pan with at least a 1-inch rim so there is less risk of cake batter spilling over while baking.
