Crush Oreos. I use a food processor. But you can crush with a rolling pin.
Set aside about 3/4 to a cup of crushed Oreos for the topping.
Melt 1 stick of butter. Add melted butter to crushed Oreos (minus the set aside portion). Mix until crushed Oreos are coated in melted butter.
Add a small portion of Oreo mixture into the bottom of each cup. This recipe will make between 6 and 10 cups depending on the thickness of your crust and how much ice-cream you add to each. Tap the Oreo mixture down to make a crust in the bottom of the cup. Freeze for at least 20 minutes.
Add a large dollop of hot fudge to each cup on top of the frozen crust. Spread fudge to cover crust. Freeze again for at least 20 mins.
Add ice-crea, to each cup. We added about a cup of ice-cream to each cup. If you want it to be more proportioned to the crust, add less ice-cream. We liked that NOT all bites of ice-cream made it down to the crust. BUT if you want it more like traditional mud pie, add a smaller layer of ice cream. We added more to fill the larger cups...and because we LOVE mint chip ice-cream:) Freeze again.
You can add an optional second layer of fudge at this point if you like hot fudge. We do. It helps to microwave the jar for just a few seconds and then drizzle the hot fudge. Otherwise you might dig into your ice-cream layer. Freeze again.
Add a large dollop of whipped cream to each cup and spread to cover ice-cream. Sprinkle Oreos on top for a finished look.
You can use this exact recipe for making traditional mud pie. Just add your layers to a 9x13 pan instead of individual cups.
