These Eggnog Mousse Bars are SO delicious and SO quick and easy to whip up! They're almost no-bake and can be made up to a day in advance. They're perfect for a festive Christmas dessert!
Serves: 16
Crust Ingredients:
  • 1 1/2 cups crushed gingersnap cookies
  • 5 tablespoons Plugrá butter, melted
Eggnog Mousse Ingredients:
  • 1 3/4 teaspoons unflavored gelatin
  • 2 tablespoons water
  • 3/4 teaspoon nutmeg
  • 3/4 teaspoon cinnamon
  • 1/4 cup sweetened condensed milk
  • 1/2 teaspoon vanilla extract
  • 1/4 cup spiced rum or Southern Comfort (or a mixture)
  • 3 cups well-chilled heavy cream, divided
  • 5 tablespoons powdered sugar
  1. Make the crust: Prepare an 8-inch square baking pan with a parchment paper sling and preheat the oven to 325 degrees F. In a medium bowl, stir together the gingersnap crumbs and melted butter with a fork until the crumbs are moistened. Press (using a flat-bottomed glass or dish) the crumbs evenly and flat into the prepared pan. Bake for 8 minutes and set it aside to cool completely (I stick mine in the fridge).
  2. Make the eggnog mousse: Prepare a large bowl of ice water and set aside as an ice bath (I just stopped up my sink and used it). Place 2 tablespoons of water in a small saucepan and sprinkle the gelatin evenly over the top. Let it soften for 2 minutes. Add in the nutmeg, cinnamon, and sweetened condensed milk. Heat the mixture over medium heat, whisking constantly, until the gelatin is dissolved and the mixture is smooth, about 2-3 minutes. Remove the saucepan from the heat, whisk in the vanilla extract and rum (and/or Southern Comfort), and then transfer the saucepan to the ice bath. Cool, whisking frequently, until the mixture is cold and thick.
  3. In the meantime, whip 2 cups of the chilled heavy cream to stiff peaks. Stir about 1/3 of the whipped cream into the cold condensed milk mixture to lighten it up, and then pour this mixture into your remaining whipped cream, folding it in gently until there are no streaks. Pour this mixture over your shortbread crust. Chill the entire dessert until it's set up nicely (a few hours). Whip the remaining cup of cream with the powdered sugar to stiff peaks for topping. Lift the bars out of the pan, slice into bars, and top each bar with a dollop of whipped cream and a sprinkling of nutmeg.

    I am the same – I hate clutter, but I have a habit of letting things accumulate. I need to be better about this coming year!! These bars look amazing. I would seriously want to eat the whole pan myself!!

    Love these! Anything with eggnog is my friend. I have really learned to let stuff go – the perfectionism, really. I am ending this year on kind of a down note, so I need to be happy enough with that, right??

    Okay, I literally have tears in my eyes right now. I loooove this post and your honesty. Your list is wonderful and I know how much those things can eat away at your psyche, even if it’s just background noise (I think that’s almost worse). You have sincerely inspired me to make my own list, thank you!! Happiest of Holidays to you and yours <3

    I know how you feel – I always look at what I’m NOT doing. I should be looking at what I AM doing! Thanks for that!! 🙂 These bars look heavenly, and I hope you have a Merry Christmas!

    I’m a “stuff” collector, too! I need to purge, purge, purge! These, however, are something I would never toss out! They’re so pretty and they sound really great! Hope you have a Merry Christmas!

    Great attitude, Julie! Our year has been full of so very many transitions, yet every one of us is adjusting well, healthy, and happy. That’s a huge accomplishment to me and worthy of celebration 🙂

      Thanks! Nope, no typo! There’s homemade eggnog in the ingredients — all but the raw eggs, that is. All the spices, cream, and vanilla are responsible for that awesome eggnog flavor that you get when making the drink 🙂 Enjoy!
