What you'll need: 1 Devils Food Cake mix, 1 large Cool Whip, 1 jar caramel (I prefer smuckers), 1 can sweet and condensed milk, and 5-6 skor bars/ heath bars chopped.
Bake you cake in a 9x13 pan. Once its cooled you cube it into 1 inch sections. Place half on the bottom of your trifle dish. Then pour half the can of sweet and condensed milk across the top, THEN half the caramel. Yes BOTH my friends, I know some of you out there use one or the other, I'm telling you right now, USE BOTH! then sprinkle with skor pieces, then cool whip.
Repeat this step all over again. But make this like 8 hours ahead of time and let it sit in the refrigerator so it can SOAK all the goodness up!
