Separate the Oreo cookies into halves while keeping the cookie pieces intact.
In a bowl mix peanut butter, powdered sugar, and vanilla extract until smooth.
Spread a thin layer of the peanut butter mixture onto the inside of each Oreo half.
Scoop a small amount of softened vanilla ice cream onto one Oreo half.
Place another Oreo half on top to create a sandwich.
Gently press the sandwich together so the ice cream spreads evenly.
Roll the edges of the ice cream in mini chocolate chips and crushed Oreos.
Place the sandwiches on a tray lined with parchment paper.
Freeze for about 2 hours until firm.
Serve straight from the freezer for the best texture.
