Preheat the oven to 350°.

Grease a 9x13 baking dish.

In a mixing bowl, combine the Oreo crumbs, ¼ cup sugar, and melted butter.

Press the cookie crust mixture into the prepared pan and press it down into an even layer. You can use the back of a spoon or your fingers!

Bake for 10 minutes. Remove from the oven and set aside to cool slightly while you prepare the filling.

Reduce the oven temperature to 325°.

Place the cream cheese in a large bowl, and use an electric mixer to beat the cream cheese until smooth. Add the sour cream and mix until combined.

Mix in the sugar and vanilla extract. Slowly add the eggs to the mixture and mix until well combined.

Separate the batter into 3 bowls. Add red food coloring to one bowl, and blue food coloring to another.

Spoon the batter onto the crust in alternating colors.

Use a knife to gently swirl the colors around to create a marbled effect.

Bake for 35 to 40 minutes or until the filling is set - the center should be just slightly jiggly.

Remove from the oven and cool completely.

Place in the fridge to chill for at least 4 hours.

Slice, top with whipped cream and sprinkles, and then serve!
