Don’t wait, don’t hesitate. Whip up a batch of this wonderful Mascarpone Mousse as soon as humanly possible. It’s one of those easy keto desserts that delights all the senses. So impossibly rich and creamy, sweet but not overly so, and with a perfect balance of flavors.
You may have noticed that creating eye-catching desserts that don’t look or taste sugar-free is kind of my specialty. And I love giving them a bit of a gourmet twist. Whether it’s Keto Kentucky Butter Cake or dreamy Keto Raspberry Mousse Tart, I love pushing the boundaries on what can be done with low carb ingredients.
I have a particular love of using mascarpone cheese in my dessert recipes. The slightly sweet flavor of this Italian-style cream cheese comes naturally from the cream, without any sugary additives. I use it everything from Keto Tiramisu to my famous Keto Chantilly Cake.
I first made this easy mousse recipe in 2015 and it’s been a fan favorite ever since! If you’ve never tried roasted strawberries, I highly recommend.

Reader’s Thoughts
“I made this today, OMG! Who ever thought to roast strawberries, omg and then add them to a mascarpone mousse ???? DELICIOUS!!!! And I had NEVER made my own whipped cream before, DEFINITELY A GAME CHANGER for me! Thank you for this recipe! It is AMAZING!” — Christa
Ingredient Notes
- Mascarpone cheese: This creamy Italian soft cheese has a naturally sweet taste. Most brands are made with cream so they have very few carbs per serving. But a few brands contain milk and have more carbs so read your labels!
- Cream cheese: Mascarpone can split easily so a little cream cheese helps stabilize the mousse. Make sure it’s at room temperature before you beat it, to ensure a smooth consistency.
- Heavy whipping cream: This lightens up the the delicious mousse.
- Sweetener: You need a powdered sweetener for the mousse. I recommend allulose for the strawberries, to make them more syrupy, but erythritol also works.
- Strawberries: Fresh berries work best for roasting, although you can do frozen if that’s all you have. You can also use blueberries.
- Vanilla extract: A touch of vanilla brings out the best flavor in the roasted berries.
Step by Step Directions
- Prepare the berries: Place the berries in a greased baking dish and sprinkle with the sweetener. Add the vanilla extract and toss to combine, then spread out in a single layer.
- Roast the berries: Roast 20 to 25 minutes, until the berries are soft and tender and have released much of their juices.
- Combine the cheeses: In a large bowl, beat the mascarpone, cream cheese, sweetener, and vanilla together until well combined.
- Whip the cream: In another bowl, beat the heavy cream until it holds stiff peaks. Fold the whipped cream into the mascarpone mixture until no streaks remain.
- Divide and serve. Pipe or spoon the mousse into 6 small dessert cups. Top with the roasted berries and serve immediately.
Tips for Success
Mascarpone can be finicky and split easily, so make sure not to over-beat it. Using some cream cheese helps stabilize it during the beating process. Make sure both the mascarpone and the cream cheese are softened before beating together.
While I highly recommend the flavor of the roasted strawberry topping, you can also use fresh berries. It would also be delicious with any one of these keto toppings:
Frequently Asked Questions
Real Italian mascarpone contains just two ingredients: heavy cream and lemon juice. It has a naturally sweet flavor from the heavy cream but has no added sugar. American-style cream cheese is made with cream and milk, along with an acid like lemon juice or vinegar. Store-bought brands also use thickeners and stabilizers such as xanthan gum to make it more shelf stable.
You can store this mousse in the fridge for up to 5 days, as long as your ingredients are fresh. You can make it a few days before serving if you need to plan ahead.

Absurdly delicious. We’re not even doing Keto or any kind of diet, nobody can complain about this being a weird ‘diet dessert’.
I cheated a little, I live in Germany now, and instead of looking for artificial sweetners, I just added small teaspoons of powdered sugar and taste tested until it was what I liked. Instead of using 8 and 4 ounces specifically, I converted to grams and then rounded up to the closest available size packaging.
This was really good, and maybe it’s just me, but I find it to be a good substitute for Cool Whip, especially since it holds form better and longer than regular whipped cream, but is still pretty airy.
So glad you liked it!
I have tried this dessert twice using blueberries because I didn’t have fresh strawberries. It is delicious!!! Thank you so much. I do have a question though regarding the net carbs. Did you include the strawberries into the net carbs or do they need to be added to the net carbs count? Keep up the good work. I really appreciate your time and effort. Edie
The strawberries are included. Only if things are completely optional do I leave them out of the nutritional counts.
Thanks so much. I plan to take this to my next cousins get-together. My daughter even eats this and she is not KETO.
Glad to hear it!
This looks heavenly! Roasted strawberries! Umm Yum!!
Oh my, I could so easily eat the entire batch myself, which kinda defeats the point of it being low carb, LOL!
