Line a 9 inch springform pan with parchment, then spray lightly with non-stick spray.
nonstick baking spray
In a medium bowl, combine the crust ingredients until it resembles moist sand. Press the crust into the bottom and sides of the prepared pan, leaving about a ½ inch or a little less of pan at the top. Press very firmly. Place the crust uncovered into the freezer.
2 cups graham cracker crumbs, ¼ cup brown sugar, 9 tablespoon butter
In a large bowl with hand mixers or in a stand mixer, whip the heavy cream, powdered sugar, and vanilla with a whisk attachment on medium-high speed until stiff peaks form, about 3 minutes. Scoop gently into a bowl and set aside in the fridge.
1 ¼ cup heavy whipping cream, ⅓ cup powdered sugar, 1 tablespoon vanilla
In the now empty bowl, use a paddle attachment to beat the cream cheese and granulated sugar on medium speed until really smooth, 30-60 seconds. Scrape the bowl well.
24 oz cream cheese, ⅔ cup granulated sugar
Add the sour cream and lemon juice on medium high for 2-3 minutes. The mixture should be fluffy, but still relatively thick. Scrape well.
¼ cup sour cream
Using a rubber spatula, add the whipped cream on top of the cream cheese mixture. Fold the cream into the batter gently and slowly so that it doesn’t deflate, turning the bowl each time you fold to help it mix more evenly.
1 tablespoon lemon juice
Pour the filling into the crust with an offset spatula and smooth the top. Cover with plastic wrap, then refrigerate for 12 hours or up to 2 days.
Once completely chilled and it is time to decorate, remove from the pan. Serve cold with toppings, if desired.
