Make the Simple Crust: In a bowl, combine your graham cracker crumbs, sugar, and melted butter until it looks like damp sand. Press this mixture firmly into the bottom of 12 mini cheesecake molds or lined muffin cups. Pop them into the freezer for about 10 minutes to chill and set.
Whip Up the Creamy Filling: Get your softened cream cheese and beat it in a large bowl until it's wonderfully smooth and fluffy. Gently mix in the powdered sugar and vanilla extract until everything is well combined. In a separate, clean bowl, whip the cold heavy cream until it forms stiff peaks. Carefully fold this whipped cream into your cream cheese mixture to make it light and airy. Now, add just a drop or two of green food coloring to get that perfect Grinchy hue. Feel free to stir in a little lime zest if you like a fresh, zesty kick!
Assemble & Chill: Spoon your vibrant green cheesecake filling evenly over the chilled crusts. Smooth out the tops with a spatula. Cover them loosely with plastic wrap and place them in the refrigerator to chill for at least 3 hours, or even better, overnight. This step is key for them to set beautifully!
Decorate & Serve: Once your cheesecakes are perfectly set, it's time for the final touch! Pipe a dollop of extra whipped cream on top of each cheesecake. Finish by gently placing a red candy heart on each one – they're now ready to bring festive cheer! Serve them cold and enjoy these delightful bites.
