HOW TO MAKE THIS KEY LIME KETO MOUSSE DESSERT RECIPE
One of my favorite desserts is Key Lime Pie so I thought I’d create a keto/low carb mousse version. Without a crust, it is nut-free for those with tree nut allergies and it keeps the carb count lower.
It took several tries to get the tartness of the Key Lime Mousse just right. Also, the measurements I have included for both the key lime zest and key lime juice may vary as some limes aren’t nearly as tart as others. So, when you make this dessert make sure to taste the recipe as you go to get the perfect tartness. I would recommend refrigerating overnight for maximum flavor.
I also have a Keto Key Lime Pie Recipe that will incorporate a pecan crust for extra texture and crunch to keto key lime mousse.
TIPS for this keto mousse recipe
Always make sure your bowl, beaters, and any measuring tools you use are completely dry. Otherwise, the added moisture could interfere with the heavy cream beating to stiff peaks.
Ingredients:
- Cream Cheese
- Heavy whipping cream
- Key lime zest
- Key Lime Juice
- Lakanto Monkfruit Powdered
Steps:
Step 2: In a separate bowl, beat on medium speed the cream cheese, Lakanto Monkfruit Powdered, lime juice, and lime zest until the mixture is smooth.
Step 3: Combine the two bowls and beat with a mixer until everything is combined.
Step 4: Spray an 8 X 8 pan with cooking spray and spread the key lime layer evenly in the bottom of the pan.

Step 5: Combine the heavy whipping cream and Lakanto Monkfruit Powdered and beat until stiff peaks form.
Step 6: Spread the homemade whipped cream on top of the key lime layer.
Step 7: Refrigerate overnight and enjoy it!
Recipe Notes:
The amount of key lime juice used in this recipe can vary depending on the ripeness and size of the limes you are using. It is important to taste this recipe as you add the lime zest and juice as you may need a little more or less.
The sugar alcohols from Lakanto Monkfruit Powdered are not included in Nutritional Information since most subtract sugar alcohols from carb count. Optional ingredients are not included in nutritional information. Nutritional information is provided only as a guide.
Tips for making this keto key lime mousse
Allow the cream cheese to come to room temperature so that it will be nice and creamy. This will make a lighter mousse with an airy texture.
Don’t overbeat heavy whipping cream or it can become grainy. If this happens, simply add a little heavy whipping cream and with a couple turns of a whisk you’ll have creamy peaks once again.
Gluten-Free Keto Mousse recipe
Along with being low in net carbs, this recipe is also gluten-free. However, if you have a gluten allergy, make sure to check the ingredients before making it. My daughter has a nut allergy, so I know you cannot leave anything up to chance.
CAN YOU FREEZE KETO MOUSSE?
Yes, you can freeze this Key Lime Keto Mousse recipe for up to two months. To thaw stick it in the fridge overnight, or until it can either be sliced or scooped out with a spoon. I have often enjoyed it frozen as well. To do so, I let it sit out for about 10-15 minutes first.
HOW DO YOU STORE KEY LIME KETO MOUSSE?
Mousse can either be stored in the fridge for five days or the freezer for two months. It will take several hours once placed in the fridge for the mousse to firm up completely. I often pop it in the freezer for 45 minutes to an hour so that it can firm up quickly before serving. Then, I set it out on the counter for a few minutes to make serving easier.
WHY ARE LIMES AND KEY LIMES DIFFERENT?
Key limes are smaller than limes and are known to pack a more acidic punch than regular limes. However, you can substitute limes for key limes if you do not have any available. Taste your keto mousse as you go because you may need to add more lime juice than you would key lime juice.

Very tasty. I made a chocolate almond crust and toasted some to garnish.
That sounds fabulous! I’m so glad you loved it.
Grace I’ve been looking for a good crust
recipe, would you mind sharing yours?
I can’t locate the carb count–only the calorie count. How many carbs, please?
Sorry about that. I had to update the back end of my blog. That info is now included at the bottom of the recipe box.
Thanks!
How much is one serving?
I divided the casserole dish into 9 equal servings. I didn’t measure them.
Is it possible to substitute Monk Fruit sweetener for the swerve confectioner?
I haven’t personally tested it, but it is worth a try.
I Notice the recipe has the monk fruit in the list of ingredients but I need the directions it says swerve.
Hey, Lily I only see Monkfruit.
I used monk fruit today. I used just shy of a 1/2 a cup and it worked perfectly
Awesome! Glad you liked it!
Planning to make this for Easter weekend. Could you tell me about how long it keeps in the fridge? Thank you!
I would say it would be the same as any other type of dessert 3-5 days.
Hi. Does it need to have the cream cheese?
Hi Kristi, I’ve only tried making it as is. I haven’t tried without cream cheese so I’m not sure how it would taste.
with or without a lock on the fridge?
I’m wondering if I did the lime zest correctly. The finished mousse had strands of the lime peel in it and I hated that texture! Is there a way to get it smooth? What did I do wrong?
Hmmmm….when you zest the limes it should be very delicate little bits of zest not strands. What did you use to zest the limes?
No key limes in Canada right now. Can I use regular limes?
Sure
Wendy look for Nellie’s and Joe’s bottled key lime juice I use that because key limes are too expensive here
I’m wondering how many carbs it is without the whip cream and 2 table spoons of swerve at the top
Try to use the MFP app.
Can you use regular limes or Meyer Lemons in the recipe?
Hi,
I am new to Keto but is there another brand of confectioners sugar that is Keto approved that I can find at my local grocery store? I really want to make this Key Lime Mousse.
Hey Maggie, I am not sure what your local grocery store would carry. Sorry!
Okay my Keto friends I have tried several Keto friendly desserts since starting this weight loss journey. I made this Key Lime Mousse (subbed lemon for lime). Well this recipe is perfect!!! I didn’t have to adjust one ingredient, perfect. Quick and easy, perfect. Delicious!!!
Bernice, so glad you enjoyed it!!
I used my coffee grinder to pulverize the monk fruit sweetener for powdered sugar! I plan this for Easter!
Hope you enjoyed!
Absolutely delicious. Love it ! I give it 10 **********.
Just made this for my husband on his birthday. It was fabulous! I used Swerve Confectionary and it was just fine. It is equal ratio to your Lakanto Monkfruit Powder.
Awesome! Glad you both enjoyed!
Thank you! The answer to my question!
This is delicious! Could not find key limes, and online it said you could add lemon with the lime as a substitute, it worked great. 3T lime zest 2T lemon zest, 2t lime juice 1t lemon juice.
Hey, Deb, glad you enjoyed!!
