Preheat oven to 300°F. Bring 4 cups of water to a boil in a pot while you make the cheesecake.
Make the crust: Stir the crushed cookies and butter together then press it into a 9-inch springform pan. Freeze until the filling is ready.
8.8 ounces Biscoff cookies, ½ cup salted butter
Make the filling: In the bowl of a stand mixer fitted with the paddle attachment, beat the cream cheese until smooth, about 2 minutes. Add the yogurt, cookie butter, sugar, eggs, and vanilla and mix again until completely incorporated.
16 ounces cream cheese, 1 cup plain Greek yogurt, ⅔ cup Biscoff cookie butter, ⅓ cup granulated sugar, 2 large eggs, 1 teaspoon pure vanilla extract
Remove the springform pan from the freezer and wrap the outside in aluminum foil.
Pour the filling onto the crust and spread it out evenly.
Place the pan into a larger roasting pan and pour the boiling water around the pan.
Bake for 65-80 minutes, or until the center jiggles only slightly but it isn’t watery in the center.
Turn off the oven and let the cheesecake set in the closed oven for 1 hour to prevent cracking.
Remove the pan from the oven and take the cheesecake pan out of the roasting pan.
Use a knife to go around the edges of the cheesecake to loosen it.
Let it cool completely at room temperature for about 2 hours, then refrigerate for at least 8 hours or overnight.
Release the springform side from the pan, remove it from the cheesecake base and place the cheesecake on a cake stand on a baking sheet with sides to catch the cookie butter when it falls.
Scoop the cookie butter into a microwave-safe bowl and microwave for 1½ minutes, stirring every 30 seconds to ensure that it’s evenly melted.
14 ounces Biscoff cookie butter
Pour the cookie butter over the cheesecake evenly and let it drip down the sides then smooth out any parts that need it.
Let it set up in the fridge for about 15 minutes while you make the topping.
Whip the heavy cream and vanilla until stiff peaks form.
1 cup heavy cream, 1 teaspoon pure vanilla extract
Fold in the powdered sugar and add it to a piping bag fitted with a piping tip (I used a Wilton 2D piping tip) then pipe whatever design that you prefer onto the cheesecake.
½ cup powdered sugar
Sprinkle on the crumbled cookies then slice and serve.
