So, I still have a few dessert recipes to share from my dessert party – and all of them lend themselves well not only to single serving desserts, but also even to bite-sized desserts, like I put together for the party! You can make this key lime mousse dessert ahead of time for easy serving when you’re entertaining, which is a critical detail for me. Key lime pie is one of my all-time favorite desserts, but it tends to be a bit heavy – this mousse version is nice and light with all the flavor. And best of all, it’s no-bake – just a couple minutes on the stove and some whipping is all you need!
We juice our own limes for this recipe, and my daughter just LOVES to “help” – but you can use bottled key lime juice if it’s available. I haven’t looked hard enough to find it, and plus – it’s all part of the bonding time in the kitchen, right? Haha.
If you’re juicing your own, pick up at least an extra lime in case they’re extra small – and they look pretty as garnish, too so an extra won’t go to waste!
- 1 c. crushed vanilla wafers (or grahams)
- ¼ c. melted butter
- 1 -15 oz. can sweetened condensed milk
- Juice from 3 key limes (about ½ cup)
- 1 tsp. Knox gelatine (1/2 an envelope)
- 1 c. heavy whipping cream
- 2 Tbsp. sugar
- Add melted butter to crumbs, and sprinkle into the bottom of your pans or serving bowls. Tamp down with the bottom of a glass to form a crust.
- In a separate bowl, mix condensed milk and lime juice together.
- In a small saucepan, sprinkle gelatine over ¼ c. cream. Allow it to rest 1-2 minutes, then stir it well over low heat until the gelatine dissolves completely.
- Add sugar to the remaining cream, and beat until fluffy while you allow the saucepan mixture to cool.
- Slowly add the mixture from your saucepan to the whipped cream, mixing on low. Then, fold the lime mixture in as well until fully blended.
- Spoon onto crust(s) and refrigerate for 2-3 hours. Top with whipped cream minutes prior to serving, and optionally, garnish with lime zest and/or lime slices.
You can print the recipe above on a sheet of 8.5×11 paper, or if recipe cards are more your style, I’ve got a free printable to offer you below! Print this on card stock for best results – I had prepared printable cards for the party, and I’m happy to share them with you guys, too!

Oh man, I totally feel your frustration! I clicked on what I thought was going to be an amazing key lime mousse recipe just last week and ended up staring at legal jargon too. Super disappointing when you’re craving that perfect tart-sweet dessert fix!
Since we’re both hunting for good key lime mousse recipes, I found this solid one during my own search: mix condensed milk, lime juice (fresh is best!), and zest, then fold into whipped cream. Chill for 4 hours – game changer! Though I’m still tweaking the lime-to-sweet ratio personally.
Have you tried making mousse before? I’d love to compare notes on getting that ideal light-but-creamy texture. Maybe we can help each other avoid more recipe dead-ends like this webpage!

Hey, I noticed the title mentions a key lime mousse dessert, but the content seems to be about terms of service and copyright. Was this a mix-up or maybe a placeholder? I’d be curious to see the actual dessert recipe if it’s available. Key lime mousse sounds like something I’d love to try making at home. Do you have any tips for balancing the tartness of key lime with the sweetness in desserts? I find that can be tricky.
