  • 3/4 cups white sugar

  6. Pour mixture in a greased 9x12 dark bottom pan.
  7. Break up the candy bars with the back of a spoon or other hard object.

Recipe Notes

Make sure to use softened butter or margarine, not melted.
Do not overbake or cake will be dry so adjust timing accordingly and start checking your cake with a toothpick at about 35 minutes.
Push some chunks of candy down into batter for a sweet surprise in your bite.
