1 small box instant chocolate pudding (3.9 oz)
2 c. heavy cream or whipping cream.
Combine the pudding mix and heavy cream in a mixing bowl. I prefer to mix with a hand held mixer, but a whisk is just fine too. If using a mixer, start on low speed until well combined. Then, switch to high speed and whip the pudding until thick and fluffy. If mousse is too thick, mix in a little bit of heavy cream or milk to reach desired consistency.
If mixing by hand, simply whisk rapidly for a couple of minutes or until mixture is nice and thick. Refrigerate until ready to use.
I love this as a filling for my chocolate cakes!
