My favorite candy bar isn't a bar at all; it's a cup. For that reason alone, making a Peanut Butter Cup Shotible seems like it would be the most obvious candidate for development, but I found myself with two hurdles to overcome.
First, I had to overcome the problem with the chocolate cup being a hazard for the teeth. Similar to the Rocky Road Shotible, I made a hybrid cup. I combine the basic vanilla wafer cookie recipe and melted milk chocolate. It made for a great consistency and the chocolate flavor wasn't overpowering.
The second challenge was to figure out what alcohol to use in the filling. What compliments peanut butter? After months of searching, I finally found a peanut flavored vodka.
I made some whipped cream and folded it into come softened cream cheese and peanut butter. I then mixed in the vodka.
