To create your No Bake Orange Creamsicle Cheesecake, follow these easy steps:

1. Prepare the Crust: In a bowl, combine graham cracker crumbs and melted butter. Mix until crumbs are evenly coated.

2. Press the Crust: Pack the mixture into the bottom of a 9-inch springform pan, pressing firmly to create a solid base. Use the back of a measuring cup for evenness.

3. Blend the Filling: In a large bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add the powdered sugar, mixing until well blended.

4. Add Flavor: Incorporate the orange zest and juice into the cream cheese mixture, blending thoroughly.

5. Whip the Cream: In another bowl, whip the heavy cream and vanilla extract until stiff peaks form. This step provides a delightful lightness to the filling.

6. Combine Mixtures: Gently fold the whipped cream into the cream cheese mixture. Use a spatula to maintain the airiness of the whipped cream, creating a creamy texture.

7. Prepare the Gelatin: If using, dissolve the unflavored gelatin in a few tablespoons of warm water. Let it cool slightly before adding it to the filling mixture.

8. Fill the Pan: Pour the fluffy filling over the prepared crust, smoothing the top with a spatula.

9. Chill the Cheesecake: Cover the pan and refrigerate for at least 4 hours, or overnight for the best results.

10. Serve: Once set, gently remove the sides of the springform pan. Slice and serve with additional orange zest or whipped cream on top for garnish.

With these straightforward steps, you’ll be well on your way to creating a divine No Bake Orange Creamsicle Cheesecake.
