Preheat your oven to 350°F (175°C). Ensure the rack is positioned in the center for even baking.
In a large mixing bowl, combine the sugar cookie crumbs with the melted butter. Stir until the mixture has a consistency similar to wet sand, ensuring all crumbs are moistened.
Firmly press this mixture into the bottom of a 9-inch springform pan to create a solid crust. Use the back of a measuring cup to ensure it’s even. Bake for 10 minutes, then take it out of the oven and let it cool completely while you prepare the filling.
In another large mixing bowl, beat the softened cream cheese until it becomes smooth and creamy, free of lumps. Gradually add in the granulated sugar, mixing until you achieve a well-combined and airy texture.
Add the pure vanilla extract and almond extract to the cream cheese mixture; blend well to incorporate the flavors fully.
Carefully add the eggs, one at a time, mixing gently after each addition just until blended. Avoid overmixing to keep the cheesecake light and creamy.
Gently fold in the sour cream using a spatula until the batter is smooth and evenly combined. This will add richness to your cheesecake.
Pour the cheesecake filling evenly over the cooled sugar cookie crust in the springform pan.
Bake in the preheated oven for 45-50 minutes, or until the edges are set while the center looks slightly wobbly. Turn off the oven and leave the cheesecake inside for 1 additional hour to gradually cool, which helps prevent cracking.
After an hour, remove the cheesecake from the oven and transfer it to the refrigerator. Chill for at least 4 hours, but ideally overnight, to ensure the best taste and texture.
Before serving, whip the powdered sugar into the remaining sour cream until smooth, then spread this mixture evenly over the top of the cheesecake. Finally, decorate with festive sprinkles for a holiday touch.
