This video shows you how to make a rich yogurt cheesecake. First, crush black cocoa cookies and mix them with milk, then press the mixture into a mold and chill in the refrigerator until firm. Next, mix softened cream cheese with eggs, granulated sugar, and unsweetened yogurt in that order, add lemon juice and vanilla extract for flavor, and sift in cornstarch to make a smooth batter. Pour the batter into the mold lined with the cookie dough, bake in a preheated oven, let it cool slightly, then chill in the refrigerator for half a day until firm. It's moist, rich, and easy to make, making it perfect for a home café or as a gift.
