Costco Copycat Vanilla Mousse Cream Filling for Cakes and more

 6oz cream cheese softened

1/2 cup powdered sugar, sifted 

1 teaspoon vanilla

2 cups heavy cream

1 package instant vanilla pudding (dry power only, 3.4 oz or 1oz sugar-free)

1.  Beat cream cheese until smooth.  Add powdered sugar and beat on low until well incorporated, scraping down the sides and bottom of the bowl intermittedly.

2.  Slowly add the vanilla and cream and whip on slow until well incorporated and smooth.  (I switched to the whisk attachment for this).  Scrape down the bowl and whisk again.

3.  Pour in the powdered pudding mix.  Increase the speed and whip for 2-3 minutes until the filling is thick.  If it get too thick, you can add 1/4 cup 1/2 cup of more cream or even 2 tablespoons of milk until you reach the desired consistency.

4.  Use a filling for cakes.  If the filling isn't super thick, you may want to pipe a frosting edge around the cake before filling with the cream mousse.
