This Low Carb cheesecake mousse is the dessert I reach for when I want cheesecake without turning on the oven. It is cream cheese and whipped cream folded into soft clouds, about 3 grams of net carb a serving, and it tastes like the inside of a cheesecake with none of the work. The trick that keeps it light is folding, instead of beating it into a dense fluff the way most recipes do.

Today for Valentine's Day I made my Valentine a sweet treat, my Cheesecake Mousse. This is such a simple recipe that you can make it this morning, let it chill, and serve it tonight. Add a few berries and you will win his or her heart. Happy Valentine's Day everyone!

Fold it for mousse, not fluff

Most low-carb cheesecake mousse recipes have you beat everything together into one thick bowl of fluff. I keep mine lighter by whipping the cream on its own to soft peaks, then folding the sweetened cream cheese in by hand. Folding keeps the air you just whipped in, so you get a mousse that holds a soft swirl instead of a dense scoop. Stop folding the moment the streaks disappear, since overworking it knocks the air back out and you are back to fluff.

The sweetener that won't go gritty

My original recipe uses Splenda, and it still works because it dissolves clean. If you would rather skip it, the one that matters is using a powdered sweetener rather than granular. Powdered erythritol, monk fruit, or allulose all fold in smooth, while granular erythritol stays sandy under your teeth no matter how long you mix, which is the number one complaint I hear about keto desserts. Use the same quarter cup, taste, and adjust, since allulose and monk fruit blends each land a little differently on the tongue.

Get the real cheesecake tang

A plain mix of cream cheese and sweetener tastes more like sweetened frosting than cheesecake. The tang is what your tongue reads as cheesecake, so I add a squeeze of fresh lemon juice, and on a richer day a spoonful of sour cream. Start with room-temperature cream cheese too, because cold cream cheese leaves lumps that lock in the second you fold in the cream, and no amount of stirring takes them back out. Soften it on the counter for an hour, beat it smooth, then build from there.

Cheesecake mousse, made ahead and dressed up

This one is a make-ahead friend. Spoon it into glasses in the morning, chill it, and it is ready by dinner, which is exactly how I served it to my Valentine. It holds in the fridge for about 3 to 4 days, lightest the first day or two before the cream starts to settle. Fresh berries are the classic finish, low in carbs and bright against the cream. It also takes a flavor twist well:

For a richer, Italian-style version, swap the cream cheese for mascarpone, which is sweeter and less tangy. Serve it next to a low-carb strawberry cheesecake or a scoop of vanilla custard ice cream, with more Low Carb desserts to round out the table.

Frequently asked questions

Why is my cheesecake mousse lumpy?

Cold cream cheese. Once you fold in the whipped cream the lumps are locked in, so soften the cream cheese fully at room temperature and beat it smooth before anything else goes in.

What sweetener works best in low carb cheesecake mousse?

A powdered sweetener so it never turns gritty. Powdered erythritol, monk fruit, or allulose all fold in smooth, and Splenda dissolves cleanly too. Skip granular erythritol, which stays sandy.

How many carbs are in this cheesecake mousse?

About 3 grams of net carb per serving with Splenda, and closer to 2 with a sugar-alcohol sweetener. The cream cheese and cream carry almost all of it.

How long does cheesecake mousse keep?

About 3 to 4 days, covered, in the fridge. The whipped cream is lightest the first day or two, so make it the morning you plan to serve it.

Can you make it without Splenda?

Yes. Swap in an equal amount of powdered monk fruit or allulose for a sugar-free version with no sugar alcohols.
