Making these cheesecake cups is a straightforward process, and I’ll guide you through it step-by-step, just like my mom did with me when we whipped up family desserts.

1. Preheat your oven to 325°F and line a muffin tin with 12 paper liners.
2. In a bowl, mix the crushed Biscoff cookies with the melted butter until well combined. Press about 2 tablespoons of the mixture into the bottom of each liner to form the crust.
3. Bake the crusts in the preheated oven for 5 minutes. Remove and let cool while you prepare the filling.
4. In a large mixing bowl, beat the cream cheese and sugar together until smooth and creamy, about 3 minutes.
5. Mix in the vanilla extract, followed by the eggs, one at a time, ensuring each is fully incorporated before adding the next.
6. Blend in the sour cream and a pinch of salt, mixing until the filling is smooth and velvety.
7. Divide the cheesecake filling evenly among the prepared crusts, smoothing the tops with a spoon.
8. Bake in the oven for 18-20 minutes, or until the centers are set but still slightly jiggly. Remove from the oven and let cool completely in the tin.
9. While the cups are cooling, melt the chocolate chips with the vegetable oil in a microwave or over a double boiler until smooth.
10. Once the cheesecake cups are cool, spoon the melted chocolate over each one, spreading gently with the back of a spoon.
11. Chill the cheesecake cups in the refrigerator for at least 2 hours before serving, allowing the flavors to meld beautifully.

Remember, patience is key here. Letting the cups cool and set properly ensures that each bite is as luscious as the next.
