Preheat oven to 350°F. Line an 8×8 baking dish with parchment paper or foil. If foil, then also grease the bottom and sides. Set aside.
Process Oreos using a food processor until fine crumbs. Add in melted butter and mix until the crumbs are completely coated in the butter.
2 1/4 cups Oreo crumbs, 6 tbsp butter
Transfer into the prepared pan and press down firmly to create a base.
Begin sprinkling each ingredient onto the base; chocolate chips, white chocolate chips, coconut, and Oreos.
3/4 cups white chocolate chips, 3/4 cups semi-sweet chocolate chips, 3/4 cups shredded coconut, 10 Oreos
Finish by pouring the entire can of sweetened condensed milk on top, covering the entire pan evenly.
14 oz sweetened condensed milk
Bake for 25-28 minutes or until slightly golden brown. Remove from the oven and allow it to cool completely before slicing. As it cools, the bars will set.
Store in an airtight container at room temperature or in the refrigerator for up to 5 days. Enjoy!
