Get Ready: Preheat your oven to 325°F (163°C). Line a mini cheesecake pan or a mini muffin tin with paper liners, or lightly grease the cavities if you're using a silicone mold.
Make the Crust: In a small bowl, combine the graham cracker crumbs, granulated sugar, and melted butter. Stir until the mixture looks and feels like wet sand. Spoon about 1 tablespoon of this mixture into each prepared cavity and press it down firmly with the back of a spoon or a small glass. Bake for just 5 minutes, then take them out and let them cool slightly.
Prepare the Creamy Filling: In a large mixing bowl, beat the softened cream cheese until it's wonderfully smooth. Add the granulated sugar and mix until everything is fully combined. Gently beat in the eggs one at a time, making sure to scrape down the bowl as needed. Finally, mix in the vanilla extract, sour cream, flour, and a tiny pinch of salt until just incorporated. Remember, don't overmix!
Fill & Bake: Evenly divide the cheesecake filling among the crusts, filling each cavity almost to the top. Bake for 15–18 minutes, or until the centers look mostly set but still have a slight jiggle. Remove from the oven and let them cool in the pan for 10 minutes. Then, transfer them to a wire rack to cool completely before refrigerating for at least 2 hours, or even overnight, for best results.
Whip the Cream: In a chilled bowl, beat the cold heavy whipping cream with powdered sugar and vanilla extract until beautiful, stiff peaks form. Transfer this delightful whipped cream to a piping bag fitted with your favorite star or round tip.
Assemble Santa Hats: Once your mini cheesecakes are perfectly chilled, pipe a lovely swirl of whipped cream on top of each one. Carefully place a hulled strawberry, pointed side up, onto the whipped cream. For that perfect Santa hat look, add a small dot of whipped cream right on the very tip of each strawberry!
