Let ice cream sit out of the freezer for 5-10 minutes to soften before assembling. Add crushed Oreo cookies into a shallow bowl.
Scoop about 1/3 cup of ice cream onto one of the monster cookies. Gently press another monster cookie on top to make a sandwich. Roll the sandwich in the crushed Oreos to coat the ice cream, gently press them into the ice cream to help stick. Place on a tray in the freezer immediately.
Repeat with the rest of the sandwiches, placing each one in the freezer when complete. Once all are assembled, wrap individually with plastic wrap. Freeze for at least 1 hour before serving to harden. Enjoy!
Use any kind of ice cream and toppings that you like! Have fun!
