Preheat oven to 350 degree F. Line a 15 x 10 x 1-inch baking sheet with parchement paper.
Press cookie dough into parchment paper lined pan. Bake for 17-19 minutes, until lightly browned.
While cookie bars are baking, combine sweetened condensed milk and white chocolate morsels in a glass bowl. Microwave for one minute, stirring until combined. Heat an additional 30 seconds, and stir until smooth.
When cookie bars come out of oven, allow to cool about 10 minutes. Spread white chocolate mixture over cookie bars and immediately press the crushed OREO cookies into the top. Chill for 30 minutes, cut into bars and enjoy!
Notes
Use any cookies you like. Oreo has so many fun flavors!
Place the Oreos in a gallon sized ziploc bag. Use a mallet or rolling pin to break the cookies into coarse pieces. I like to crush them into a variety of sizes for better texture. You can pulse them in a food processor too, but be careful not to pulverize the cookies into a powder.
Use a clean, sharp knife (not serrated) for slicing these bars. I got 48 bars about 2 inches wide. You can cut them smaller to get even more bite-sized servings!
