Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.
In a large mixing bowl, prepare the funfetti cake mix according to package instructions by combining the cake mix, water, vegetable oil, and eggs. Mix until smooth.
Fold in the crushed Oreo cookies until evenly incorporated.
Pour the batter into the greased baking dish and bake for about 30-35 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool completely in the pan set on a wire rack.
Once cooled, crumble the cake into a large bowl. Add the cream cheese frosting and combine until the mixture is well-mixed and holds together.
Scoop out about 1 tablespoon of the mixture and roll it into a ball. Place the formed cake pops onto a parchment-lined baking sheet. Repeat until all the mixture is rolled into balls.
Freeze the cake pops for 30 minutes to help them retain their shape.
In a microwave-safe bowl, melt the white chocolate chips in 30-second intervals, stirring in between until smooth.
Dip the end of each lollipop stick into the melted chocolate, then insert it into the cake pop to help it stay in place.
Fully dip each cake pop into the melted white chocolate, allowing any excess to drip off.
Before the coating sets, sprinkle rainbow sprinkles on top to add some extra flair.
Place the finished cake pops upright in a piece of styrofoam or a cake pop stand to allow them to set completely.
Notes
Allow cake pops to cool completely before crumbling for best results.
