Iron skillet chocolate pie recipe?

Does anybody have a recipe for Iron Skillet Chocolate :Pie? I tried one that used corn starch and cocoa powder, but my husband didn't like it. He said the recipe tasted too much like pudding. He said his mom made one that had butter, bakers chocolate, sugar, flour, egg yolks, topped with meringue and baked. He does not know the amounts of each ingredient, and I have not been able to find one using bakers chocolate and omitting the corn starch
