To make the whipped cream cheese layer, whip together the cream cheese, vanilla extract, and sweetener in a large bowl, using hand held mixer. Beat until smooth. Add milk and pudding mix, stirring constantly as you pour pudding mix into bowl to prevent lumps from forming. Continue to mix until smooth. Fold in whipped topping. Store in fridge until ready to layer trifle.
Once coffee is chilled, you are ready to begin layering. Using a large trifle dish, begin layering with lady fingers that have been quickly dipped into chilled coffee.
Once the first lady finger layer is complete, start next layer which is the whipped cream cheese/pudding layer. Spread pudding layer evenly over lady finger layer.
Next, sprinkle a layer of cocoa powder over the pudding layer.
Begin next layer, starting with lady fingers dipped in coffee. Repeat pudding and cocoa layers. Repeat one more time, ending with cocoa layer.
Sprinkle mini chocolate chips over the top if desired! Return to the fridge until ready to serve. Enjoy!
