Servings: 12
Author: Susan (Between Naps on the Porch)


  • Duncan Hines Devil's Food Cake Mix
  • 1 cup Kahlua coffee-flavored, rum-based liqueur
  • 1-2 bags of small Heath candy bars or 8 large Heath bars
  • 2 family size whipped topping
  • For the Cake Mix you'll need:
  • 3 eggs
  • 1/3 cup vegetable oil
  • 1 cup water


  • Bake Devil's Food cake in a 9 x 13 inch pan the day before you plan to serve the trifle.
  • After cake has cooled, cut it into squares about 1 1/2 to 2 inches square.
  • Leaving cake (sliced up) in the pan, pour Kahlua all over the top of the cake, getting the liqueur down in-between the slices.
  • Cover with plastic wrap and put in refrigerator overnight.
  • Next day, 2-4 hours before serving time, assemble trifle in a large bowl or trifle dish as follows.
  • Layer of cake (one third of cake)
  • Layer of whipped topping
  • Layer of Heath bar (I layer it on pretty heavily)
  • Repeat above layers twice more but only put a light sprinkling of Heath Bar on the top when completing the last layer. I always mound up the last layer of whipped topping, it just looks pretty.


Tip: Break the toffee bars up with your fingers and use kitchen shears to break up some of the larger pieces before chopping it up in a food processor. That way you won't have to over-chop the toffee to get it crunched up into small, bite-size chunks. The toffee softens up inside the trifle and it's nice to come across it while eating the trifle.
