Lightly grease a 9" round springform pan with cooking spray. If desired, place a parchment paper round on the bottom of the pan and spray again. Set aside.
In a medium bowl, combine the graham cracker crumbs, light brown sugar and melted butter until moistened and combined. Pour the crust mixture into the prepared pan and press into an even layer. Place in the freezer for at least 30 minutes.
Next, add the orange gelatin to a heat-safe bowl and whisk the boiling water and orange zest into it until dissolved. Let cool completely to room temperature (about 30 minutes).
In the bowl of a stand mixer, cream the cream cheese, granulated sugar and 1 teaspoon of the vanilla extract together with the paddle attachment until fluffy and smooth, about 1 minute. Scrape out of the stand mixer bowl and place in another small bowl. In the stand mixer bowl, add the heavy whipping cream, confectioners' sugar and remaining 1 teaspoon vanilla extract and using the whisk attachment, whip on HIGH speed until stiff peaks form, about 5-7 minutes. Fold half of the whipped cream mixture into the cream cheese mixture. Fold the remaining half of the whipped cream mixture into the cooled orange gelatin mixture.
Add half of the cream cheese mixture to the bottom of the pan and spread it out into an even layer; top with half of the orange mixture. Remember, we are working with two different textures and the orange mixture, while thickened, will still be runnier than the cream cheese mixture so layering will be tricky. Dollop the remaining cream cheese mixture evenly over the orange layer and try your best to spread a little - doesn't have to be perfect and it may look lumpy; this is okay! Lastly, add the last of the orange mixture.
Cover and refrigerate at least 8 hours or overnight. Carefully remove from the pan and garnish with whipped cream and orange segments, if desired.
