End the lunch party with a deliciously creamy keto lemon mousse. Tangy mascarpone mousse paired with a toasted almond gluten-free crust.
Can I tell you something? I love lemons.
Lemon curd, lemon cake, lemon oil, keto lemon mousse, you name it. That fresh tart flavor is perfect to pair with a cream or sweet treat. And of course, there’s always lemon garlic shrimp, but you get the idea.

What are Meyer lemons?
Now when you look at the pictures in this post, what do you see? They are not in fact oranges as they may appear. They’re Meyer lemons, or rather a cross between a lemon and a mandarin orange.
I ended up trying these out, not on purpose but because I was in a hurry. Yes, the bag of Meyer lemons looked bright, fresh, and like good fruit so I grabbed them! Did I realize it was not a regular lemon?
However, good came out of it! While I myself prefer a regular lemon, my husband is loving these Meyer lemons. He eats them plain and thought they were perfect for the keto lemon mousse.
So the moral of the tale is, if you’d like to be adventurous and try new things, go for the Meyer lemons! If you’d prefer the traditional tart tang of a true lemon, make sure you get those. Lesson to self.
While I think you’ll love my super helpful tips and fun stories, I also realize we are sometimes pressed for time and just need a good recipe!

What is a mousse?
The term “mousse” comes of course from our friends the French. Way back when, chefs would try to impress their employers. Just like today.
The chefs of the royal courts would whip up cream or egg whites into what they called a “crème mousseuse”. Literally, this translates as foamy cream. They made all sorts of sweet and savory variations on this idea.
Because who doesn’t like whipped cream?
Therefore, a chocolate mousse, keto pumpkin mousse, or lemon mousse can mean any number of things. This is true as long as it has some sort of whipped foam, often meaning bubbles, in the dessert.
Sometimes egg yolks are added to chocolate or other ingredients to make it more rich and dense, but there are so many ways to make a mousse.
This easy whipped keto lemon mousse just happens to be one of my favorites!
TO MAKE KETO LEMON MOUSSE YOU’LL NEED:
- medium or large-sized bowl
- a spatula
- a fork
- measuring cups and spoons
- hand-held or standing mixer
- serving dishes or ramekins
A grapefruit is just a lemon that saw an opportunity and took advantage of it.

For the crust or topping:
- finely ground blanched almond flour
- powdered sweetener (such as Swerve Confectioners)
For the mousse:
- heavy whipping cream
- mascarpone cheese (or cream cheese will work too)
- powdered sweetener
- vanilla extract
- lemon extract (or lemon essential oil)
- lemon zest
HOW TO MAKE KETO LEMON MOUSSE
So how do you make a keto lemon mousse?
Well, to start, decide how you’d like to serve it. I strongly advise NOT skipping the crust. It adds a crunch and salty and nutty flavor that goes well with the lemon mousse.
For the toasted almond crumble, you can serve it under the mousse or sprinkled on top.
Toasted almond crumble
First, put the almond flour in a skillet on medium heat. Second, spread it out evenly over the pan. Stir it around continuously for 3-4 minutes to toast the almond flour.
You might be tempted to skip the toasting, but I really love the flavor it brings out. It’ll only take a few extra minutes.
Next, stir 2 teaspoons of powdered sweetener into the toasted almond flour.
Then, once it’s evenly dispersed, pour in the melted butter. I like to use a fork to smash the mixture into crumbs.
Now set aside the crumble to use as topping. Or, if you’ve decided to serve it under the mousse go ahead and divide it evenly into 6 ramekins or glasses.
(Disclosure: the glass in the pictures is 2-3 servings.)
How to make the whipped lemon mousse
To make a mousse, something needs to be whipped. In this case we’re whipping heavy cream.
First off, take out a bowl and mixer and whip the cream to stiff peaks.
To whip the cream, make sure the bowl is clean and cool. The cream should also be cold or else it will melt and not whip up. Whip the cream until it stands up in a peak without falling in on itself when you turn the beater upside down.
Also, if the cream is whipped too long it can turn to butter, so keep an eye on it!
Next, set aside the whipped cream, and take out another medium bowl. Then using a mixer, beat the mascarpone and all the other ingredients together until smooth.
Now’s the fun part! Spoon the whipped cream into the mascarpone cheese mixture and combine it well. Take the spatula around the sides and cut through the middle so as little air as possible is lost from the whipped cream.
Lastly, to serve. Usually I just spoon it in the serving dish, but you can also pipe it in for a better presentation. Top with some extra lemon zest if you like and refridgerate until ready to serve.
This recipe can be made the day before and served from the refrigerator. However, I like the texture best if it’s served immediately.
How to make keto lemon mousse fat bombs
Bonus! Did you know you can also make an easy fat bomb snack to get you through mid-afternoon?
I like to spoon or pipe circles of the lemon mousse mixure onto a silicone mat on a baking tray. Sprinkle the toasted almond crumble on those for taste and to make it look nice. My piping skills may need some practice!
Then, just pop them into the freezer for a couple of hours. After that, remove them to a zipper bag or airtight container. They’ll store in the freezer for about a month so you can grab one or two when you need.
Although really, I doubt they’ll last the month.
Keto fat bombs
To be perfectly honest, I’ve never liked the term fat bomb. Perhaps it’s the fear of having too many. Or maybe it’s that ingrained from childhood avoidance of fat.
But, our bodies need fat to burn. If not, I’m constantly snacking on other unhealthy things that do me no good. And can I tell you, sometimes one of those little keto lemon mousse bombs is the perfect thing to get me through until dinner.
So why not try it out? A keto lemon mousse for your next lunch or dinner party? Or save it for yourself in fat bomb portions in the freezer. Either way, I hope you love it.
