    Extra ingredients make for an 18oz cake box size, we used to could buy. Extra egg will make a pound cake consistency, which is a plus! I also add a jar of hot fudge sauce! Perfect!

  2. Julie Johnston says:

    I would say, the extra ingredients is to equal up to what we used to buy in the 18oz cake mix box. The extra egg will give it a bit more bounce and moisture, kind of a pound cake consistency. Perfect!!!!

  3. Joyce leiser says:

    Need more info using the flour, sugar, etc. added to the cake mix? What does do to the cake?

  4. Sandy Fitzpatrick says:

    Can this be frozen with cool whip
    On top??

  5. It would be helpful to have exact amount of the caramel topping. There are several different sizes of this at the store.

  6. So just to be sure I make the cake mix according to directions on box using 3 eggs plus the one egg in this recipe total 4 eggs?

    1. Kelly Gregg says:

      I believe so. I was also confused but if you don’t use the wet ingredients per the box instructions it’s extremely dry. So once I began it all made sense to add it all together.

    I always use German Chocolate cake mix

    1. Kasey Schwartz says:

      Great variation!

  8. I love this cake! I use a straw instead of a fork or skewer as a “poker”. It removes a tiny bit of the cake so the sweetened condensed milk/caramel mixture really soaks in good. I use Butterfinger instead of Heath bars too sometimes. Yum!

      What a great tip! Glad you enjoyed!

  9. Donna fioritto says:

    Do u mix the Carmel sauce and sweetened condensed milk together first or pour them seperate- not clear on that! And what iscreason for extra flour and egg

    1. Kim Smith says:

      I was wondering about the extra flour and sugar myself……

      1. How has this not been answered yet?! It’s the most important detail that’s been left to our own to decide. 😆

  10. I live in Canada and haven’t seen Heath bars in the store… What would an alternative candy bar be?

    1. Butterfingers! Or you could order Heath bars on Amazon maybe.

    2. Denise Kennard says:

      Look in the baking section. Where the chocolate morsels are. There should be bags of chopped Heath bar pieces.

  11. I’d like to make this a layered round cake. Any suggestions on proportion changes?
