Notes
Cookie Crust Consistency: Ensure that the cookie crumb mixture for the crust is well combined with the melted butter and evenly pressed into the pan. This will help create a solid and uniform crust base for the dessert.
Chilling Time: Refrigerating the dessert for 2-3 hours before serving is crucial for allowing the layers to set properly. This chilling time helps the pudding layers firm up and allows the flavors to meld together, resulting in a delicious and cohesive dessert.
Garnish Variation: Feel free to get creative with the garnish. In addition to the ground cinnamon and nut topping, you can sprinkle extra crushed Oreos or toasted pecans on top for added texture and flavor. Customize the garnish to suit your taste preferences and presentation style.
