Place Oreos into a food processor and process until fine crumbs form. Set aside.
Using a mixer on medium speed, whip together the cream cheese and and butter until mixture is smooth and creamy. Slowly mix in powdered sugar. Add in vanilla and crushed Oreos and mix until combined.
Line a small bowl with plastic wrap. Place cream cheese mixture into plastic lined bowl. Cover and refrigerate at least 2 hours.
Once firm, carefully remove cheese ball from bowl and place onto a wax paper lined flat surface. Lightly place a small star shaped cookie cutter on top of the cheese ball. I used a knife to make a small mark on both sides of the cookie cutter to create sections so I knew where to change colors. Remove cookie cutter.
Sprinkle one color of the sparkling sugar onto each of the 3 sections. From left to right, I did red first, then white, then blue.
Place star cookie cutter back on top. Using the color that you want for the star, sprinkle the sugar onto the inside of the cookie cutter until covered. Carefully remove cookie cutter and you'll have a star.
Serve immediately or refrigerate until ready to eat.
