Beat cream cheese until soft and smooth.
In the microwave, heat white chocolate in 20-second increments until melted.
Mix the melted white chocolate into cream cheese and mix well.
Add in vanilla and sugar and mix well again.
Beat the last egg slightly then add it to the cream cheese mixture. Mix until fully combined.
Using a spoon, add spoons of the cheesecake mix onto the Oreo and smooth the top as best as you can. Don’t spread the cheesecake mix to the edges. If you do it will burn.
Add the rest of the broken Oreos on top of the cheesecake mixture. Bake 35-40 minutes or until the brownie begins to pull away from the pan.
Cool on the counter for 1 hour. Then cover and refrigerate 2-3 hours before serving.
