Combine Biscoff cookie crumbs, granulated sugar, and melted butter in a bowl and press firmly into the bottom of mini cheesecake pans to form crusts.
In a large bowl, beat cream cheese, powdered sugar, Biscoff spread, and vanilla extract until smooth using an electric mixer.
Add heavy cream to the mixture and whip on medium-high speed until thick and fluffy.
Pipe the cheesecake filling onto the cookie crusts, slightly above the top edge of the pans.
Chill the cheesecakes in the refrigerator for 12 hours or overnight before removing them from the pans.
Whip heavy cream, powdered sugar, and vanilla extract together until medium-stiff peaks form for the whipped cream topping.
Slightly melt additional Biscoff spread in the microwave for about 30 seconds for drizzling.
Assemble by piping or spooning melted Biscoff spread over each cheesecake, adding a swirl of whipped cream, sprinkling cookie crumbs, and topping with half a Biscoff cookie.
