If you are going to make the homemade frosting, just mix the frosting ingredients in a stand mixer until you have a nice frosting.
Break up the Oreos in a food processor. Add the rum and vanilla, process. Add the milk. Process. Add the honey and process again.
By the time, all the cookie should be broken up, and you might have something that looks like black sand.
Remove from the food processor, and put it into the bowl of a stand mixer. Do not process any further, or you will burn out your motor.
Add the frosting, chips, and walnuts. Stir until all are well combined.
Unless it is a cold day, refrigerate the mixture for about 30 minutes to let it firm up.
Have ready a size 24 ice cream scoop, and a dish with chocolate jimmies. Also, have ready a nice serving dish.
Take a scoop of the cookie mixture and roll in in the chocolate jimmies. Put the finished ball on the serving plate, and continue to roll until all the cookie mixture is finished.
Refrigerate at least one hour before serving.
Notes
You could omit the chips or walnuts, and you could use powdered sugar instead of jimmies. You can also dip the balls in melted chocolate.
