Ingredients
- 1 box devil’s food chocolate cake mix
- 1/2 cup chocolate chips
- 16 oz heavy whipping cream
- 1 can sweetened condensed milk
- 2 tbsp sugar
- 2 tsp vanilla extract
- 1 stick butter
- 1 cup dark brown sugar
- 1/4 tsp salt
- 2 cups powdered sugar
- 1 bag Heath Bar candy bits
Instructions
Make the chocolate cake:
- Before baking the cake, place a metal mixing bowl in the freezer to chill.
- Mix and bake devil’s food cake according to box instructions.
- Bake in two 9-inch round pans.
- While the cake is baking and cooling, prepare the whipped cream, chocolate ganache, and salted caramel frosting.
Make the whipped cream:
- Take the chilled mixing bowl out of the freezer.
- Add 1 cup of heavy whipping cream, 2 tablespoons of sugar, and 2 teaspoons of vanilla extract to the bowl.
- Using the whisk attachment on a stand mixer, mix on medium speed until stiff peaks form, about 5 minutes.
- Place whipped cream in the fridge until ready to use.
Make the salted caramel sauce:
- Add the stick of butter to a small saucepan and place over medium heat.
- When the butter is melted, add the cup of dark brown sugar and 2 tablespoons of heavy cream. Whisk until sugar is completely dissolved, then add the salt.
- Continue stirring occasionally until the mixture starts to bubble. Allow mixture to bubble for 2-3 minutes. Do not stir while mixture is bubbling. Swirl gently, being careful not to let the mixture swing up the sides.*
- When the mixture has bubbled for at least 3 minutes and has thickened slightly, remove from heat and poor into a heat proof bowl or jar. Set aside and allow to cool completely.
Make the chocolate ganache:
- Add chocolate chips and 1/2 cup of heavy cream to a small saucepan and place over medium heat.
- Heat mixture until chocolate is completely melted and mixture is homogenous. Stir constantly to prevent burning. Remove from heat immediately.
Assemble cake:
- Place the first cake layer on a plate or cake stand. Use the blunt end of a fork or spoon to poke holes in the surface of the cake, pressing approximately 3/4 of the way through the cake.
- Pour sweetened condensed milk over the surface of the cake, using a spoon to spread evenly and press into the holes. I only used half the can. It’s rich – a little goes a long way.
- Repeat with chocolate ganache.
- Scoop whipped cream on top of ganache layer and spread evenly, leaving a 1/2 perimeter around the edge of the cake so the whipped cream doesn’t squish out when you add the top cake layer.
- Sprinkle with Heath bits.
- Add second cake layer on top of whipped cream.
Finish the caramel frosting:
- Pour the cooled caramel sauce into the mixing bowl of a stand mixer fitted with paddle attachment.
- Add 2 cups of powdered sugar and start mixing on slow speed, working up to medium as frosting comes together.
- Slowly pour in 2 or 3 tablespoons of heavy whipping cream and continue mixing.
- If frosting is too thin, add more powdered sugar until frosting reaches desired consistency. If frosting is too thick, add another tablespoon of heavy cream.
- Whip on high speed until frosting is thick and fluffy.
- Frost cake, then sprinkle with more Heath pieces.
Notes
*This is to prevent crystallization, which will result in a gritty sauce. If mixture starts to crystallize, cover with a lid for a couple minutes. Trapping the heat will form condensation, which will melt the crystals. You can also add a little more water and bring to a boil to re-melt the crystallized sugar.
