CW -What kinds of production volume are you looking to do?FYI, generically, you can do these with what's called a "one shot" machine. Which one-shot machine is right for you depends on a number of factors - volume is one, the viscosity of the filling could be another, putting candy cups in the molds before filling might be the most challenging.
I have an easy way to make these. Use a round magnetic mold or cup mold. Mold the shell. You can use a transfer sheet to jazz it up.For the filling I use 100 gr melted cocoa butter, 170 gr powdered sugar, 650 gr peanut butter and salt to taste. Blend well, pipe in molds. Bottom next day. Recipe good for 7 magnetic molds of 15 pcs= 105 per batch.Some people use peanut flour to replace some of the powdered sugar.I easily make and sell about 200 per week.
