In a large mixing bowl, beat the cream cheese until smooth. Add the sugar, salt, and vanilla extract, and mix until well combined.
12 oz cream cheese, 2/3 cup granulated sugar, 2 teaspoon vanilla extract, 1/2 teaspoon salt
Mix in the sour cream, and the cookie butter into the cream cheese mixture. Make sure to scrape the sides and mix until well incorporated,.
1/3 cup sour cream, 2/3 cup Biscoff spread
Add in the eggs one a time and mix until combined. Scrape the sides again then add in the cornstarch and mix gently in order not to incorporate too much air into the batter.
2 large eggs, 1/2 teaspoon cornstarch
Pour the filling over the crust in the springform pan, smoothing the top with a spatula.
Bake in the preheated oven for about 30-35 minutes, or until the edges are set but the center is slightly wobbly. You can either bake your cheesecake in a water bath (making sure to wrap the bottom of the pan tightly with foil) or place a dish full of hot water in the oven alongside your cheesecake to maintain high moisture in the oven.
Once baked turn off the oven and crack the oven door open slightly to allow the cheesecake to cool down for an hour.
Remove the cheesecake from the oven and allow it to cool completely. Melt the Biscoff cookie butter for 5-10 seconds just enough to soften it slightly then spread it onto your cheesecake. I used an offset spatula to create the swirls you see here. Refrigerate for at least 4 hours, or overnight, to set.
Slice and enjoy the creamy and indulgent Biscoff cheesecake!
