In a large bowl, beat the cream until it holds stiff peaks.
In another large bowl, beat the cream cheese until very smooth. Add the powdered sweetener and the vanilla extract and beat until well combined.
Reserve a few tablespoons of whipped cream for the tops of the dessert cups. Fold the remainder into the cream cheese mixture until nicely combined.
Place the sandwich cookies in a blender or food processor and pulse a few times to turn into crumbs. Hold back about 1 tablespoon and fold the rest into the whipped cream mixture until well distributed.
Optional Step: Crush the brownie bites until they resemble coarse crumbs. Divide between 4 small dessert cups.
Pipe or spoon the mousse into the cups and top each with a small dollop of whipped cream. Sprinkle with the remaining cookie crumbs.
You can serve them right away or refrigerate for an hour to firm them up a bit. Delicious either way!
Notes
Make sure the cream cheese is nice and soft for the best consistency. Room temperature is not sufficient, so I recommend giving it a very quick zap in the microwave to soften it up more. If you can't access the pre-made sandwich cookies, you can still make this dessert easily. Simply make the same "keto cookie crumble" that I used for my cheesecake and brownies.Storage Information: You can store this Keto Cookies n Cream Mousse in the fridge for up to 5 days, as long as your cream and cream cheese were fresh. I do not recommend freezing this dessert.
