NOTE: you may use a full size muffin tin. Recipe will yield 9-10 cheesecakes.
Preheat the oven to 350 degrees then line the muffin tin with papers and set aside.
Coarsely chop the snickers candy bars then set then aside as well.
Crush the pretzels to crumbs using either a food processor or add to a zip-top bag and crush with a rolling pin then transfer to a small bowl.
Pour the melted butter over the top of the pretzel crumbs, add the sugar and blend then divide the pretzel mixture between the cups using the back of a measuring spoon to gently press into the bottom of the liner.
Add the room temperature cream cheese, vanilla, granulated sugar and peanut butter to a medium bowl. Cream together using a hand mixer then fold in the egg and blend completely.
Using a spoon, blend about half of the coarsely chopped Snickers into the mix by hand. Reserve the remaining candy topping until after the cheesecakes are baked.
Divide the cheesecake mixture between the cups (they should be almost full) and bake at 350 degrees, 12-15 minutes or until the edges are set and there's only a slight jiggle in the center. Remove from the oven to cool.
To make the ganache, pour the chocolate chips and 2 tablespoons of the milk (more may be added as needed) into a microwave safe bowl. Heat on high 30 seconds then stir. If the chips aren’t all melted microwave a few more seconds until the ganache is smooth and a consistency that will let you drizzle it easily.
Once the cheesecakes are completely cooled, drizzle the ganache over the top followed by a drizzle of caramel sauce then top with the remaining candy pieces. Refrigerate 2 hours up to overnight.
