Creating No Bake Fireworks Oreo Cheesecake Bars is easy if you follow these steps:

1. Prepare the Pan: Line an 8×8-inch square baking dish with parchment paper, leaving some overhang for easy removal later.
2. Make the Crust: In a mixing bowl, combine the crushed Oreo cookies and melted butter. Stir until well combined. Press the mixture firmly into the bottom of the prepared baking dish.
3. Mix the Cheesecake Filling: In a large bowl, beat the softened cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until well blended.
4. Whip the Cream: In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
5. Add the Sprinkles: Gently fold in the fireworks sprinkles, being careful not to deflate the whipped cream.
6. Assemble the Bars: Pour the cheesecake filling over the Oreo crust, spreading it evenly. Smooth the top with a spatula.
7. Chill: Cover the dish with plastic wrap and refrigerate for at least 4 hours or overnight for the best results.
8. Cut into Bars: Once chilled, lift the cheesecake out of the pan using the parchment paper. Cut into squares or rectangles.
9. Garnish: Sprinkle additional fireworks sprinkles on top before serving.

These steps will guide you in creating these incredible cheesecake bars effortlessly.
