Cheese Cake Mousse
In the bowl of a stand mixture add your cream cheese, sugar, and vanilla. Mix on low speed for a minute then increase speed to medium high until cheese is softened.
Scrape the cheese mixture off the side of the bowl. Then add the other half of the whipped cream to your mixture. Fold in the cream.
Assemble
You can use individual trifle cups or one large trifle dish. Either way start by adding about a half an inch layer of the shortbread crumbles. Then add about half an inch layer of the cheese cake mousse on top. Spread out this layer evenly. Then add about half an inch layer of the mango mousse on top of that. Repeat until you reach the top of your dish. Garnish with a few fresh mangos if you have any. Serve and store cold.
