Follow these steps to create the delightful No-Bake Creamsicle Cheesecake:

1. Prepare the Crust: In a large bowl, combine the graham cracker crumbs and melted butter. Mix until well combined. Press this mixture into the bottom of a 9-inch springform pan to form an even crust.

2. Make the Filling: In another bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add the powdered sugar, mixing until incorporated.

3. Add Flavor: Pour in the orange juice, orange zest, and vanilla extract. Mix until everything is well blended and smooth.

4. Whip the Cream: In a separate bowl, whip the heavy cream until stiff peaks form. This will give your cheesecake a light and airy texture.

5. Combine Mixtures: Gently fold the whipped cream into the cream cheese mixture. Be careful not to deflate the whipped cream; you want to maintain its lightness.

6. Prepare Gelatin (if using): If you want a firmer cheesecake, dissolve the unflavored gelatin in warm water. Stir until fully dissolved, then allow it to cool slightly before adding to the cream cheese mixture.

7. Pour the Filling: Pour the cheesecake filling over the prepared crust in the springform pan. Spread it evenly with a spatula.

8. Chill: Cover the cheesecake with plastic wrap or foil and refrigerate for at least 4-6 hours, preferably overnight, until firm.

9. Release the Cheesecake: Once chilled, carefully remove the sides of the springform pan to reveal your beautiful cheesecake.

10. Garnish (optional): For an extra touch, you can garnish the top with whipped cream, orange slices, or additional orange zest before serving.
