Preheat the oven to 350°F (177°C) for the crust. Grease a 9-inch springform pan and line the bottom with parchment paper. If using a water bath, wrap the outside of the pan tightly with foil to prevent leaks.
Add the Biscoff cookies to a food processor and process until fine crumbs form, about 2 cups. Stir the crumbs together with the melted butter until evenly combined.
32 Biscoff cookies, 5 tablespoons salted butter
Gently press the crust mixture into the bottom of the prepared pan and slightly up the sides. Bake for 10 minutes, then remove from the oven. Reduce the oven temperature to 300°F (150°C).
In a large bowl, beat the cream cheese until completely smooth and creamy. Take your time here. This step sets the foundation for a lump-free cheesecake.
32 oz full-fat cream cheese
Add the sugar and beat until fully incorporated. Scrape down the sides and bottom of the bowl to ensure everything mixes evenly.
1½ cups granulated sugar
Mix in the Greek yogurt, melted butter, vanilla, and salt. Continue scraping the bowl as needed so the batter stays smooth and uniform.
1½ cups plain full-fat vanilla Greek yogurt, 8 tablespoons salted butter, 2 teaspoons vanilla bean paste or pure vanilla extract, ½ teaspoon salt
Add the eggs one at a time, mixing well after each addition. Once the eggs are added, mix gently. Overmixing at this stage adds air, which can lead to cracks as the cheesecake cools. The batter should be thick, silky, and smooth.
5 large eggs
Pour the cheesecake batter over the pre-baked crust and smooth the top.
Place the springform pan into a roasting pan or large baking dish. Carefully pour hot water into the outer pan until it reaches about halfway up the sides of the springform pan, creating a water bath. This helps the cheesecake bake gently and evenly.
Bake at 300°F for 60 to 75 minutes, until the center reaches an internal temperature of 145°F. The edges should be set, and the center should still have a slight jiggle.
Turn the oven off, crack the oven door open slightly, and allow the cheesecake to rest in the oven for 30 minutes. This gradual cooling helps prevent cracks.
Remove the cheesecake from the oven and let it cool completely at room temperature.
Once cooled, cover and refrigerate overnight before removing the springform ring or slicing. Cheesecake needs time to fully set, and this step makes all the difference.
