Follow these simple steps to create your No Bake Fireworks Oreo Cheesecake:

1. Prepare the Crust: In a medium bowl, combine the crushed Oreo cookies with melted butter. Mix thoroughly until all crumbs are coated.
2. Form the Base: Press the Oreo mixture firmly into the bottom of a 9-inch springform pan. Use a flat spatula to create an even layer.
3. Make the Filling: In a large mixing bowl, beat the cream cheese until smooth. Gradually add in the powdered sugar and vanilla extract, mixing until well combined.
4. Fold in Whipped Topping: Gently fold in the whipped topping until evenly blended, ensuring there are no lumps.
5. Add Mix-ins: Stir in the mini marshmallows and half of the rainbow sprinkles, reserving the rest for garnish.
6. Combine Filling & Crust: Spread the cream cheese filling over the crust, smoothing the top with a spatula.
7. Chill: Cover the cheesecake with plastic wrap and refrigerate for at least 4-6 hours, preferably overnight for the best texture.
8. Add Toppings: Once set, remove the cheesecake from the springform pan. Top with additional Oreo crumbles, remaining rainbow sprinkles, and a few extra mini marshmallows for decoration.
9. Slice and Serve: Cut the cheesecake into slices and prepare to wow your guests with this amazing dessert!
