Creating the Irresistible No-Bake Orange Creamsicle Cheesecake is straightforward. Follow these easy steps:

1. Prepare the Crust: In a bowl, mix together graham cracker crumbs, granulated sugar, and melted butter until well combined.
2. Form the Crust: Press the mixture firmly into the bottom of a 9-inch springform pan to create an even layer. Set aside.
3. Soften the Cream Cheese: In a separate bowl, beat the softened cream cheese until smooth and creamy.
4. Add Sugar: Gradually add in the powdered sugar and continue to mix until fully combined.
5. Incorporate Flavor: Pour in the orange juice, orange zest, and vanilla extract, mixing until the mixture is smooth and well-combined.
6. Whip the Cream: In another bowl, whip the heavy cream until stiff peaks form.
7. Fold Together: Gently fold the whipped cream into the cream cheese mixture, being careful not to deflate it.
8. (Optional) Prepare Gelatin: If using gelatin, dissolve it in 2 tablespoons of water and let it sit for a few minutes until it blooms. Then, gently warm it until it dissolves completely. Gradually fold it into the cheesecake mixture.
9. Fill the Crust: Pour the cheesecake filling into the prepared graham cracker crust, smoothing the top with a spatula.
10. Chill: Cover and refrigerate the cheesecake for at least 4 to 6 hours or until firm.
