Melt white chocolate chips in a microwave safe dish. Microwave for 30 seconds and then stir. Continue with 30 second intervals until melted. Stir in between each interval.
Add sweetened condensed milk to the melted white chocolate. Stir quickly as the texture changes quickly. Add in crushed Oreos and vanilla extract and stir until completely mixed in. Set aside a small handful of cookies for topping the fudge at the end.
Pour into a parchment paper line 8x8 baking sheet. Spread to cover the bottom of the pan. Top the fudge with remaining crushed cookies and gently press down. Place in the refrigerator about 4 hours until set and firm.
Remove from the pan and peel the parchment paper away and cut into square to serve.
Notes
Do not use off-brand white chocolate, it doesn't melt properly causing the consistency of the fudge to change.
Store leftover fudge in the refrigerator or freeze.
Use Almond Bark instead of white chocolate.
Milk Chocolate can be used for a chocolate experience.
Put in a ½ teaspoon of mint extract or mint Oreos.
A peanut butter flavor fudge would be ¼ cup of creamy peanut. Or use peanut butter Oreos.
Pumpkin Oreo is tasty, add 2 tablespoons of pumpkin puree for a fun fall twist.
Replace original Oreo's with birthday cake or golden Oreos.
