Line a square baking pan (9 x 9) with parchment paper and lightly grease with baking spray.

Combine white chocolate chips and sweetened condensed milk in a medium saucepan over medium heat and stir until melted.

Stir in pudding mix, followed by the marshmallow fluff once pudding mix is fully incorporated.

Remove from heat and fold in crushed Oreo's.

Pour fudge into the prepared pan and chill in the fridge for at least 4 hours.

ENJOY!!
