Preheat your oven to 350°F (175°C) and line an 8x8-inch baking dish with parchment paper for easy removal of the bars.
In a mixing bowl, combine the Biscoff cookie crumbs and melted butter until well mixed. Press this mixture evenly into the bottom of the prepared baking dish to form the crust. Bake for 10 minutes, then remove from the oven and let it cool slightly.
In a separate bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add the powdered sugar, continuing to mix until well combined.
Add the Biscoff cookie spread and vanilla extract to the cream cheese mixture, beating until everything is well incorporated and smooth.
Fold the whipped cream into the cream cheese mixture gently until there are no streaks.
Spread the cheesecake filling evenly over the cooled Biscoff crust, smoothing the top with a spatula.
Refrigerate for at least 4 hours, or overnight, until the cheesecake is set.
Once chilled, lift the cheesecake out of the baking dish using the parchment paper and cut it into bars.
Sprinkle the top with additional Biscoff crumbs for garnish before serving.
Notes
Serve the bars on a decorative platter with whipped cream and extra Biscoff cookie spread.
