We think this is very reminiscent of strawberry shortcake, but obviously without the shortcake.
Speaking of strawberries, we use a simple strawberry sauce over this keto mini cheesecake recipe too. We love strawberry cheesecake!

We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.
Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.

How To Make Strawberry Mousse:
Make the strawberry puree: First up, you’ll want to make the sweet strawberry sauce. Add berries and sweetener to a blender or food processor and process/blend until everything is broken down and you have a gorgeous pink liquid.
Pop that strawberry mixture in the fridge for about 30 minutes. We want our strawberry puree to be nice and cold.
Whip the cream: Add the whipping cream and sweetener to a glass bowl and use an electric mixer to whip the cream until stiff peaks form.
We’re using 1/4 cup of the powdered sweetener here and it doesn’t make the cream super sweet. This is a very light and delicate tasting dessert, not overly sweet or rich.
If you’d like the cream to be sweetener, up the powdered sweetener to 1/3 or 1/2 cup, depending on your preference. Our kids like this on the sweeter side, but I love it with just 1/4 cup of sweetener.
Pour 1/2 of the strawberry puree into the cream and gently fold it all together using a rubber spatula. Your cream should have ribbons of light pink throughout.
Divide the remaining strawberry puree evenly between 6 small dishes and then top it all off with dollops of the cream.
The Secret to Perfect Mousse:
Here’s something I learned the hard way: you absolutely have to chill that strawberry puree before folding it into the whipped cream. I know it seems like an unnecessary step when you’re craving dessert RIGHT NOW, but trust me.
Just blend your strawberries with sweetener, pop it in the fridge for 30 minutes while you do other things and then proceed. Your patience will be rewarded with sweet strawberry mousse.
Storage:
Fridge life: Keeps for 2-3 days stored separately (puree in one container, cream in another) so you can assemble fresh servings.
Best serving practice: Store components separately and assemble right before eating for the prettiest presentation and best texture.
Freezer situation: Don’t do it – whipped cream gets weird when frozen and thawed, and you’ll be sad.
FAQ’s:
Sure! You could just as easily make a mousse out of raspberries, blackberries, or blueberries.
We like monk fruit sweeteners the best but erythritol based sweeteners like Swerve are also popular! Allulose based sweeteners work too.
I have not tried it but I think that it would probably be okay to use frozen and thawed strawberries here. They should blend up into a puree just as easily, but the flavor may not be as good as fresh!
