To other commenters: A typical bag of Nestle’s chocolate chips is 12 oz or 340g. I think anything in the neighborhood will work fine. I might use a bit more chocolate next time to make the chocolate layer thicker.

Also, I just used the fridge (not the freezer) to cool things down, and it worked fine. I left it in a little longer. I also store the bark in the fridge.

Thanks again for the great recipe! I have sent several friends this way for the recipe.
