In a medium microwave-safe bowl, combine 14 ounces of white chocolate with 14 ounces of sweetened condensed milk. Microwave for 1 minute on high, then stir gently.

Return the bowl to the microwave and heat in 15-second intervals, stirring after each, until the mixture is fully melted and creamy.

While the chocolate mixture is melting, take 28 Oreo cookies and place them in a ziplock bag. Crush the cookies into fine crumbs.

Once the chocolate mixture is smooth, gently fold in the crushed Oreos until fully integrated.

Line a medium baking dish with parchment paper. Pour the Oreo mixture into the prepared dish, spreading it evenly.

Place the baking dish in the refrigerator to chill for at least 8 hours.

After the fudge has set, lift it out of the dish using the parchment paper and cut into squares.
