1-First, prepare the pudding filling by combining one box (3.9 oz) of white chocolate pudding mix with 2 cups of cold 2% milk in a mixing bowl. For that signature Grinch look, add 2-3 drops of neon green gel food coloring and 1-2 drops of regular green food coloring, then mix until soft peaks form this takes about 2 minutes with an electric mixer.

2-Next, spread the vibrant green mixture evenly into the Oreo pie crust, ensuring it’s level for a neat finish. Pop the pie into the refrigerator for at least 3 hours to let it set properly, which helps the flavors meld and the texture firm up.

3-Adding the Toppings: After chilling, take the pie out and spread a layer of ½ container of whipped topping over the pudding for extra fluffiness. For the final touch, sprinkle ½ cup green sanding sugar and ½ cup mini red heart sprinkles across the top. If you want to get creative, add ½ cup of large red heart sprinkles on each slice before serving to make it even more festive.
