Creating the Decadent Baileys Chocolate Cheesecake Trifle is an enjoyable process. Follow these detailed steps to ensure success:

1. Prepare the Cookie Crust: In a mixing bowl, combine chocolate cookie crumbs and melted butter. Mix until the crumbs are evenly coated. Set aside.

2. Make the Cheesecake Filling: In another bowl, beat the softened cream cheese with powdered sugar using an electric mixer until smooth and creamy.

3. Add Baileys and Vanilla: Slowly pour in the Baileys Irish Cream and vanilla extract, mixing on low speed until fully combined and smooth.

4. Prepare the Whipped Cream: In a separate bowl, whip the heavy cream and sugar until stiff peaks form.

5. Combine Whipped Cream with Cheesecake Mixture: Gently fold the whipped cream into the cheesecake mixture until well incorporated. This will give the cheesecake a light and airy texture.

6. Layer the Trifle: In a large trifle dish or individual glasses, begin layering the dessert. Start with a layer of chocolate cookie crust at the bottom, followed by a layer of the cheesecake filling.

7. Repeat Layers: Continue to layer the cookie crumbs and cheesecake mixture, creating multiple layers until you reach the top of the dish.

8. Chill: Cover the trifle with plastic wrap and refrigerate for at least four hours, or overnight to allow the flavors to meld beautifully.

9. Garnish: Before serving, sprinkle the grated chocolate and additional chocolate cookie crumbs on top for a delightful finishing touch.

10. Serve and Enjoy: Dish out servings for yourself and your guests, and watch as they delight in every bite.

These simple steps will guide you in creating a show-stopping dessert that impresses all who indulge in it!
