Add the butter, cream cheese, and vanilla extract to a medium bowl and beat together with a hand mixer until well combined.

Add the powdered sugar, half a cup at a time, to the cream cheese and butter mixture and beat together until well combined. Continue until all powdered sugar is fully incorporated with the butter and cream cheese. Add any add mix-ins if preferred and stir to thoroughly combine.

Place the beaten mixture into the freezer for 45 minutes to chill.

Add the chocolate chips to a glass bowl and place it in the microwave. Heat it for 15 seconds at a time, stirring often, until the chocolate is mostly melted. Remove the bowl from the microwave and continue to stir until the remaining chocolate chips melt.

Remove the chilled filling from the freezer and add each ball to the melted chocolate one at a time. Use a fork to coat the ball in chocolate before dripping off any excess chocolate and placing the ball back on the parchment paper. Repeat until all bon bons are coated in chocolate. Place the bon bons in the fridge for an additional 15 minutes to fully set before enjoying.
