Make the No Bake Christmas Cookie Lush Recipe: a festive, layered Oreo dessert you can assemble in 20 minutes and chill for 4 hours.
Line a 9x13 baking dish with parchment for easy removal and gather the crushed cookie mixture. Crush 36 vanilla Oreo cookies into fine, sandy crumbs in a food processor or by rolling them in a heavy zip-top bag until uniformly crumb-sized; mix those crumbs with 6 tablespoons of melted butter and half a tablespoon of holiday sprinkles so the crumbs bind into a slightly glossy, compactable paste. Press this mixture firmly and evenly into the bottom of the pan using the flat base of a measuring cup or the back of a spoon so the crust sets dense and even. Keep the pan on the counter, with a small bowl of extra crumbs nearby for later touch-ups.

Soften one 8-ounce package of cream cheese and beat it smooth with 1 cup powdered sugar and a splash of peppermint extract until it becomes shiny, lump-free and satiny; this should read as a soft, scoopable cream that holds gentle peaks. Fold in one 8-ounce tub of whipped topping using a silicone spatula, then sprinkle in another half tablespoon of holiday sprinkles so the mixture stays airy but spreads cleanly. Transfer and gently spread this pale, pillowy cream cheese layer over the chilled crust, smoothing it into a uniform layer but keeping a hint of rustic texture at the edges so the layers read clearly when sliced.

Whisk the cheesecake instant pudding mix with 2 cups of cold milk until it thickens to a glossy, custard-like consistency—thick enough to leave a ribbon when the whisk is lifted. Stir in another half tablespoon of sprinkles for flecks of red and green. Carefully spoon the cooled, dense pudding over the cream cheese layer, using a small offset spatula to spread it as an even, distinct middle layer; take care to keep the top of the cream cheese intact so the three layers remain separate and visible.

Spread the remaining tub of whipped topping over the pudding, smoothing it to a pillowy, cloud-like finish with soft ridges that catch the light. Crush the final 12 vanilla Oreos into a mix of fine crumbs and rough chunks, then scatter them across the top so some pieces are rustic and chunky while others are dusting. Finish with the remaining sprinkles for bright holiday pops; the top should read as festive, textured, and generous—an inviting contrast of creamy white, golden cookie bits, and tiny red and green confetti.

Chill the assembled pan for at least four hours (or pop it briefly into the freezer for firmer slices) until the layers knit and slices come away clean. When ready, use a sharp knife to cut the lush into squares that reveal clean, distinct bands of crust, cream cheese, pudding, and fluffy topping—each slice should show embedded cookie bits and sprinkle specks. Plate a single festive square on a white plate and present it with scattered crumbs and a few stray sprinkles on the quartz for a joyous, homey finish.
