To prepare the pretzel crumbs

1. Stir together the melted butter, brown sugar, and salt. Stir in the pretzel crumbs and set aside while you prepare the mousse and cream topping.

To prepare the mousse

1. Beat together the cream cheese and cookie butter on medium speed in the bowl of a stand mixer. Scrape the sides of the bowl as needed to ensure it becomes well combined. Add the sugar and vanilla and beat until well combined.
2. In a separate bowl, whip together the cream until stiff peaks form. Fold half of the cream into the cookie butter mixture. Once combined, fold the remaining whipped cream in. Set aside while you prepare the whipped cream topping.

To prepare the whipped cream topping

1. Beat the cream on medium low speed until it begins to froth slightly. Increase the speed to medium high and beat until soft peaks form. Add the sugar and vanilla and then continue beating just until stiff peaks form.

To assemble the cookie butter mousse cups

1. Using a piping bag fitted with a large round tip, pipe the mousse mixture into 6- 6 ounce glass jars. You will add approximately 1/3-1/2 cup of the mixture to each jar. Alternatively, you can just scoop the mixture in to a bowl or the jars if you don’t have a piping bag, or use a plastic bag with the end clipped off to pipe it in. Sprinkle 2 tablespoons of the pretzel crumbs over top of the mousse and then top with a large dollop of whipped cream. Sprinkle with any remaining pretzel crumbs and then serve!
