Preheat your oven to 350°F (175°C). Combine graham cracker crumbs and melted butter. Press into the bottom of a 9-inch springform pan. Bake for 10 minutes until lightly golden, and cool completely.

Beat softened cream cheese until smooth. Gradually add granulated sugar until combined. Stir in the zest and juice from the oranges.

Melt dark chocolate and let it cool slightly before folding into the cream cheese mixture along with the heavy whipping cream.

Pour the filling over the crust, spread evenly, cover with plastic wrap, and refrigerate for at least 4 hours.

Before serving, drizzle melted chocolate on top and garnish with fresh orange slices.
