Preheat your oven to 350°F. Use foil to wrap the exterior bottom of a 9-inch springform pan to keep it watertight, and grease the interior generously. Smash your Oreos into crumbs using a food processor or by pressing them in a sealed bag. Blend crumbs with melted butter in a bowl until they cling together, then pack the mixture firmly into the pan's base with your hands or a flat-bottomed tool. Bake for about 8-10 minutes, just until the edge firms up a bit. Put aside to cool.

Lower the oven heat a bit to 325°F. In the meantime, pour an inch or two of warm water into a big roasting tray or deep baking sheet. Put this water pan on the lower oven rack for 5-10 minutes, so it's ready to create steam while your cheesecake bakes.

Use a mixer—either stand or handheld with beaters—to whip the cream cheese until no lumps remain. Blend in sugar, salt, vanilla, and flour, scraping down the sides as needed to ensure smoothness. Keeping the mixer on low, add eggs one at a time and stop mixing as soon as each one disappears. Carefully fold sprinkles into the batter by hand. Pour this creamy mixture onto your baked crust, then even out the top with a spatula.

Let the cheesecake bake for 60-90 minutes. You’ll know it's done when only 3-4 inches in the middle jiggle slightly. Switch off the oven, leave the cheesecake inside, and let it cool gently for another 1-2 hours as the oven loses heat. Take it out and leave it at room temperature until totally cooled. Then tuck it into the fridge overnight. The next day, run a knife along the pan's inner edges before you unlock the springform.

In a tiny pot, warm heavy cream just shy of boiling—stir every few seconds. Pour this hot cream over your white chocolate chips in a bowl, stir non-stop until silky smooth. Add a hint of food coloring if that’s your thing. Cool the ganache slightly before smoothing it across the firm, chilled cheesecake.

Whisk together heavy cream, powdered sugar, vanilla extract, and the vanilla pudding powder until stiff peaks show up. Scoop it into a piping bag with a star nozzle. Pipe swirls around the cheesecake's rim and finish things off with extra colorful sprinkles (if you feel fancy).
