Heath Bar Cake, you complete me.

Print Recipe Jump to Recipe

Heath Bar Cake has quickly become a favorite dessert in our house (it’s main cake competition is this oatmeal cake with coconut walnut icing). It is caramel-infused chocolate cake covered with cool whip and heath candy bar crumble!




Do you, cake eater, take this delicious heath bar cake above all other cakes to journey together throughout the years in the delicious affair of dessert eating?

I do!

Ah, Heath Bar Cake my delicious friend, I’m so glad you came into my life. Your moist chocolate caramel infused base, your heath bar candy crumble cool whip top…I’m gonna eat you up, I don’t think I can stop. You complete me.


I don’t remember exactly when Melissa first made Heath Bar Cake for me. Sometimes it’s hard to remember specific details surrounding moments of euphoria. Or maybe it’s just that I have requested it so many times since that day that the details have now gone fuzzy. She probably gets tired of me asking for it, but I can’t help it. I love Heath Bar cake!


I love you Heath Bar Cake

The Secret to Great Heath Bar Cake

The secret to great heath bar cake is the caramel infusion of the cake layer which keeps it nice and moist and delicious! Perhaps you are familiar with the TV show Friends and the episode in which someone steals Ross’s Thanksgiving leftover sandwich (MY SANDWICH!) causing him to go Red Ross. The key to the sandwich was an extra gravy soaked slice of bread known as “the moist maker”. I liken this cake to that. Moist and oh so delicious.  And if someone steals my Cake I might just go Red Ross!

  • 1 box Devils Food Cake Mix (16.5 ounces)
  • 3 eggs
  • 1/3 vegetable oil

  • Use a fork to poke holes in the cake.
  • Pour the sweetened condensed milk and caramel sauce over top of the cake.
  • Refrigerate overnight (you can refrigerate less, but it doesn’t taste as good) so the condensed milk and sauce can really seep into the cake.
  • Spread cool whip on top.
  • Smash the heath bars up (take out your aggression out on them with a rolling pin while they are in a ziplock bag).
  • Sprinkle heath bar on top. That’s it, cake time!
