Ingredients

Crust:

  • 48 Biscoff Cookies from 1 ½ x 8.8-ounce packages
  • ½ cup (113 g) unsalted butter melted
  • teaspoon salt

Filling:

  • 24 ounces (680 g) full fat cream cheese softened to room temperature
  • ¾ cup granulated sugar
  • 1 cup Biscoff cookie butter spread
  • ½ cup (120 g) sour cream
  • 1 teaspoon (5 ml) pure vanilla extract
  • 3 large eggs at room temperature

Biscoff Topping:

Instructions

To Make the Crust

  • Adjust the oven rack to the lower-middle position. And preheat the oven to 350°F (180°C,) or 160°C for a fan oven.
  • Line a 9x13-inch (23x33 cm) baking pan with parchment paper, letting the paper overhang on the sides so that the bars are easy to remove later. Set the pan aside.
  • Crush the Biscoff cookies using a food processor or blender until they are turned into fine crumbs. In a medium mixing bowl, mix together the crumbs, melted butter, and salt.
  • Add the crumb mixture to the prepared baking pan and press down firmly to cover the bottom of the pan in an even layer.
  • Bake in the preheated oven for 10 minutes. Remove from the oven and let cool on a wire rack. Leave the oven on.

For the Cheesecake Filling

  • Add the softened cream cheese and sugar to the bowl of your stand mixer (or use a hand mixer and a large mixing bowl). Beat on medium speed until smooth and creamy.
  • Add the cookie butter, sour cream, and vanilla extract and beat until well incorporated, scraping down the sides of the bowl with a rubber spatula a few times.
  • Then add the eggs, one at a time, mixing just until each egg is incorporated into the filling. Avoid overmixing.
  • Pour the filling into the crust and use a spatula to spread it out evenly. Bake at 350°F (180°C) for 30-35 minutes, or until lightly browned and the center of the cheesecake is set. (It's ok if the center is soft, as long as it's no longer liquidy)
  • Allow the cheesecake to cool in the pan on a wire rack until it is cool to the touch. Then, transfer to the refrigerator and chill for 4 hours.

For the Topping

  • Microwave the cookie butter in a microwave-safe bowl for 30 seconds, then stir. If needed, microwave for an additional 15 seconds and stir again.
  • Pour the melted cookie butter over the chilled cheesecake and spread out evenly. Return the pan to the fridge to chill for 30 minutes, or until the topping is firm. Slice into squares to serve.

Notes

  • You should be able to find Lotus Biscoff cookies and spread in the grocery store. You can also substitute store-brand cookie butter and speculoos cookies if you like. 
  • Instead of traditional Biscoff cookies, try making the crust with cream-filled Biscoff instead. You will need to use about 30 cookies, and the crust will be a bit thinner, but much sweeter.
  • One jar of Biscoff spread has just slightly less than 2 cups of cookie butter in it. You can use 1 cup for the filling, and all of the remaining spread for the topping, but it may not be as thick as shown. For best results, pick up two jars!
  • If you would like to make these bars extra sweet, feel free to add an additional ¼-½ cup of granulated sugar. I kept the sugar light since the cookies are already quite sweet. 
  • To Store: Keep cheesecake bars in the refrigerator in an airtight container for up to 5 days. Freeze for up to 3 months.
