What’s better than a homemade cake from scratch? No frosting is needed, you will top your cake with Heath candy bars.

There is something that is just somehow more sophisticated about the word “toffee” than the word “caramel.” Many kids were gobbling up Snickers and Whatchamacallit chocolate bars growing up, but it seemed only adults ate Heath bars. Maybe it was the candy’s simplicity that kept kids away, or perhaps the blame rests on greedy parents who never told their children how delicious the bars. For whatever reason, Heath bars remained the domain of folks who could see over the counter at the grocery store.

This Heath Bar Cake recipe recreates the flavor of the candy bar and then goes above and beyond by topping it with a layer of crushed candy. No matter when you discovered the joy of Heath bars, you are sure to love this cake. And, don’t be stingy. Go ahead and share this cake with the little ones. You can still keep the candy bars a secret!

What Makes This Recipe Special?

Many Heath Bar Cake recipes are floating around on the internet, but most of them use a chocolate cake mix and whipped cream with a sprinkling of Heath bar pieces on top. This recipe is very different. It is based on a classic crumble topping.

If you are not familiar with making a crumble topping, it is pretty easy to do, and you don’t even need a stand mixer.

  1. In a large bowl (remember, you will be adding the rest of the ingredients to this bowl after making the crumble), combine the butter, flour, and brown sugar. The butter should be very cold and cut into small cubes.
  2. Quickly use your hands to push all the ingredients into a solid block. Make sure there are no dry bits on the bottom of the bowl or stuck to the outside of the block.
  3. Use the back of a fork to start breaking apart the block into a crumble, not crumbs.
  4. Reserve a cup of the crumble and place it in the fridge.
  5. Continue with the recipe with the remaining crumble.

Tips for Making a Heath Bar Cake from Scratch

  • Keep the Heath bars in the freezer. Popping the chocolate bars in the freezer overnight makes them easier to break into small pieces. Place the frozen bars in a plastic bag and hit them with the back of a heavy spoon. Don’t smash the bars too hard. You want the pieces to be about the same size as your crumble.
  • Keep things light. Use a light-colored baking pan for this recipe. Darker pans will bake the cake faster and color the exterior, two things you don’t want in this recipe. If you only have dark-colored baking pans, there is no need to buy a new one for this recipe. All you need to do is wrap the outside of the entire pan with tinfoil with the shiny side facing out.
  • Keep the cake covered on the counter for 2-3 days. If you plan on storing it longer, let the cake cool completely and then wrap well with plastic wrap and then with tinfoil, and store flat in the freezer for up to 2 months. Allow frozen Heath Bar Cake to thaw on the counter before eating.

      If the cake was warm you might want to wait a bit before cutting. If the cake was cold when you tried to do this, I would use a bread knife on this, that may help. It may also help if you dampen the knife before cutting.

    I’ve been making this recipe for many years, but mine calls for buttermilk instead of regular milk…either way, it’s delish!! Thanks for reminding me it’s time to make it again!

    You can get milk chocolate Heath bar bits now which would make this a step easier. Going to bake this to take to my church quilting group on Monday!
