I love these FFPBBars but can no longer find packaged Coconut Pecan Frosting Mix. Have been using canned frosting and adding additional coconut and extra pecans to make filling thicker so that it doesn't run.

Yes, the recipe my family had called for a Jiffy frosting mix, which isn't sold any more. For years we've just used a homemade mocha frosting instead as the entire filling, but we make the frosting a bit thicker than usual.

As a child, my mother used to make these. We found this recipe to be the closest to it, however we are unable to find the dry frosting mix as well. We always add about a third of a cup of flour to the filling in order to thicken it up.
