In a pot add 1/3 good scotch whisky.....1/3 honey.....and 1/3 whipping cream. Heat to almost boil and serve in VERY SMALL glasses

I am trying to make banana flips that I loved so much as a kid from the late 50's and on. I'm getting closer, but it's just not quite there yet with the filling. What I'm wondering is what happens if I change the proportions of the butter and shortening so it's either all butter or mostly butter. Here is the ingredient list: 2-3/4 cup powder sugar 1/4 cup flour 3/4 cup butter 3/4 cup butter flavor shortening 3/4 cup milk 1-1/2 tsp banana extract Any help would be greatly appreciated. Or if you have a recipe I could try that you think is good that you would be willing to share.
