We’re in a loop, in case you haven’t noticed. We’re just rotating around a trifecta of seasonal favorites: mint, gingerbread, and eggnog. Round and round, we go. Where it stops, nobody knows! The pattern has to break, eventually, right? Perhaps… but not today!

I had eggnog mousse in my head as an idea, and I found a positively ancient recipe among my Gma’s stash that I adapted to make this mousse. Hers was actually a pie recipe – eggnog cream pie – and it didn’t have anything to do with coconut or rum, so my recipe is altogether pretty different from the original. I think maybe the only ingredients that remained the same were gelatin and eggnog. Nevertheless, it did sort of serve as the inspiration!

It’s super creamy and rich, full of coconut and rum flavors. Kind of like a Pina Colada gone Eggnog. Or a wintertime/holiday Pina Colada, if you will. But in mousse form. Yes, that. Are you still with me? It also boasts lots of cinnamon and nutmeg! Spicy goodness.

I really wanted to add something crunchy to this. I fought the temptation to add walnuts. When I made it last weekend though, S.O. was suffering from a toothache for the 3rd day in a row and he pleaded his case against anything even mildly crunchy. I gladly obliged since he was pretty earnest about it. At that point, I was also leaning back towards keeping this dessert ultra-creamy anyway.

It turned out that he needed a root canal so he was really quite serious about the ‘no crunchy’ demand… poor thing. I’ve never had one (knock on wood), and I pray I don’t anytime soon. Ugh.

Are you surprised though? In this house? It was a matter of time before one of us needed a root canal. So in between sleeping, choking down gargantuan Tylenol tablets (laced with a very special ingredient), and eating his usual 4 bananas/day, he also stuffed himself silly with this Creamy Coconut Rum Eggnog Mousse. And I don’t think he ate it only because he couldn’t eat sturdier foods. I like to believe it’s because it was just plain delicious.

Well, I know that is why I ate mass quantities. :)

    I love the idea of eggnog mousse, Sarah! Such a fun dessert to make and even better to eat! And I love the addition of coconut, too. You made a great dessert for your husband to eat while he was recovering from a tooth ache, and I’m sure he ate a ton because he loved it!

    looks great…I love coconut and all the spices in there. And I really need to try it… going to get a small pack when I go grocery shopping today. Taking your words for it…that it doesn’t taste like egg 😀

      Yes, you’ll have to trust me… I promise it doesn’t taste like egg! That would be super gross actually as a beverage, wouldn’t it? I think you’ll like it, but I want to hear your thoughts when you try it!!

      I know what you mean! I like it in coffee too! And I like to mix into other things so it’s not quite as strong and thick – it’s so great mixed into things! Hope you’re having a great weekend, Stacey! :)

    • says

      Yay! I’m so glad you like it, Thalia! It was super simple and it’s sooooo good. It’s rich, but still light! Let me know if you try it!

      It really felt like a wintertime Pina Colada with the coconut and rum flavors! It was quite delish, I must say! :) Thanks so much, Kelly! You’re always so kind!
