This keto cheesecake fluff is a creamy, spoonable dessert made with softened cream cheese and whipped heavy cream. I stir in the first third of the whipped cream to loosen the base, then gently fold in the rest. Serve in four dishes or use it as a dip for berries; each quarter batch has an estimated 2.8g net carbs.
When I want cheesecake flavor without turning on the oven, this is an easy bowl to put together. Cream cheese gives it the tangy base and whipped cream makes it light enough to scoop with a spoon or dip into with a strawberry.
There are three base ingredients: cream cheese, powdered sweetener and heavy cream. A teaspoon of lemon juice and a pinch of salt round out the flavor. The lemon and salt are optional in the original recipe, but I like what they add to the richness of the cream cheese.
The useful little trick is in the folding. I stir about a third of the whipped cream into the cream cheese first. That loosens the thick base so the rest of the cream can be folded in gently. Scrape around the bowl and lift the mixture over itself, stopping when it is evenly combined.
Start with softened cream cheese and cold heavy cream. The five-minute time is mixing time once the cheese is ready; softening and any chilling come before or after that. Beat out lumps in the cream cheese before adding the whipped cream.
Divide the finished fluff into four equal portions. The amount of air you whip in changes the final volume. Berries, syrups and other toppings are additional to the plain recipe estimate.
This simple base works well in different dessert combinations. Pair a small portion with keto chocolate mousse for a layered dessert, or bake my keto cheesecake when you want a firm slice.
Flavor ideas and dessert combinations
For a simple variation, blend a little vanilla or another food-grade flavoring into the cream cheese before adding the whipped cream. Extract strengths vary, so start with the product’s suggested amount in a small portion and taste before flavoring the entire batch.
Lemon zest adds citrus aroma without a large amount of extra liquid. Fresh berries can go on top just before serving. Liquid syrups and fruit puree can thin the fluff, while peanut butter, cocoa and pudding powders change its consistency and sweetness.
For a chocolate or peanut butter dessert with its own ingredient amounts, follow my chocolate mousse or peanut butter mousse recipe. They can be layered with a portion of plain fluff. The nutrition on this page does not cover added flavors or a combined dessert.
Toppings that work
Fresh berries add tartness and work as dippers. Add washed, dried berries just before serving so their juice does not collect in the stored fluff.
Chopped nuts, toasted unsweetened coconut or low carb granola give a little crunch against the soft cream. Add them to individual portions rather than stirring them into the storage container.
Sugar-free chocolate chips or a drizzle of syrup are optional finishes. Check the product’s serving information and ingredients; sugar-free toppings still change the nutrition and may add allergens.
How to store it
Cover and refrigerate promptly at 40°F or below. Use within 3-4 days as conservative storage guidance, and follow any shorter date on your ingredients. Keep the total time spent softening, preparing and serving perishable ingredients under 2 hours, or 1 hour above 90°F.
The fluff can firm up in the refrigerator. Keep berries, syrup and crunchy toppings separate until serving to limit extra moisture and sogginess.
Freezing changes the whipped texture and can make the mixture grainy or separate after thawing. Try a small portion first if you want a frozen dessert, and do not expect it to thaw back into the original airy fluff.
How to make keto cheesecake fluff
Make a smooth base. Beat the softened cream cheese with the powdered sweetener, lemon juice and salt. Check the bowl for lumps now, while you can still smooth them out without deflating whipped cream.
Whip the cream separately. Measure 3/4 cup of liquid heavy cream before whipping. Beat the cold cream until it holds stiff peaks, stopping before it becomes grainy.
Lighten, then fold. Stir the first third of the whipped cream into the cheese mixture. Gently fold in the rest until the color and texture are even. There is no fixed number of turns that works for every bowl or batch.
Portion and chill. Divide among four dishes and serve, or cover and refrigerate for a firmer texture. Keep berries and crunchy toppings separate until serving.
In a large bowl, cream together cream cheese, powdered sweetener, lemon juice and salt until smooth and silky. Set aside.

Frequently Asked Questions
Does the cheesecake fluff need to chill before eating?
I eat it right away sometimes, and it's good. But I've noticed it tastes better after 30 minutes to an hour in the fridge . The lemon juice and sweetener settle into the cream cheese, and the texture firms up slightly. If you can wait, chill it. If you can't, it's still good straight from the bowl.
Do I have to use powdered sweetener?
I always use powdered. I've tried granulated erythritol, monkfruit, and allulose in this, and granulated creates a grainy texture that doesn't go away no matter how much you mix. If powdered isn't available, I pulse granulated sweetener in a blender for about 30 seconds first. That fixes it.
Can I make this without an electric mixer?
I've done it with a hand whisk. It works, but your arm will feel it . The cream cheese step is fine with a whisk and some effort. The heavy cream is the hard part. It takes a solid 5-8 minutes of vigorous whisking to reach stiff peaks by hand. I'd say use a hand mixer if you have one. If you don't, it's still completely doable.
Can I freeze this long-term?
I freeze it all the time. I scoop it into silicone ice cube trays or small containers and it keeps for up to 3 months . The texture changes though. Frozen, it turns into something like cheesecake ice cream, and I actually love it that way. Don't thaw and expect the fluffy mousse texture to come back. Eat it frozen or let it sit for just a few minutes at room temperature.
Can I use this as a frosting or cake filling?
I've piped it onto keto cupcakes and used it to top flourless cookies . It holds up if the cream cheese is properly softened and the whipped cream hits stiff peaks. For frosting, I keep it thicker by using half a cup of heavy cream instead of 3/4. For filling between cake layers, I use the full amount so it stays lighter. Chill whatever you frost for at least an hour before serving or it slides.
How do I fix it if the cream cheese turns lumpy?
I've had this happen when I rushed the softening. If the cream cheese is still cold in the center, you get lumps no matter how hard you beat. My fix: 15 seconds in the microwave, then beat again before adding anything else . This only works at the cream cheese stage though. Once you've folded in the whipped cream, lumps are locked in and there's no saving it.
What's the difference between cheesecake fluff and cheesecake mousse?
I use the terms almost interchangeably. The main difference is that mousse recipes sometimes use gelatin for structure, and fluff leans on whipped cream for airiness. This recipe is pure whipped cream and cream cheese, no gelatin, so it's lighter and more cloud-like than a traditional mousse. It's one of the simplest low carb cream cheese desserts I make. If you want something denser, my keto chocolate mousse goes in that direction.
Can I make this with sugar-free pudding mix?
I have. A tablespoon or two of sugar-free instant cheesecake or vanilla pudding mix folded into the softened cream cheese gives it a thicker, more set texture and a deeper flavor. I add it before the whipped cream so it blends in smooth. I start with a small amount, since too much pudding mix can turn the flavor artificial. I still reach for the four-ingredient version most nights, but the pudding trick is my go-to when I want it to hold a piped shape longer.
How can I make keto cheesecake fluff?
I cream 8 oz softened cream cheese with 1/4 cup powdered sweetener, 1 teaspoon lemon juice, and a pinch of salt, then fold in 3/4 cup heavy cream whipped to stiff peaks. It takes 5 minutes and makes 4 servings. Stir the first third of the whipped cream in to loosen the base, then fold the rest in gently so the fluff stays airy.
How to make low carb cheesecake filling?
This fluff is my low carb cheesecake filling. Beat 8 oz softened cream cheese with 1/4 cup powdered sweetener and 1 teaspoon lemon juice until smooth, then fold in 3/4 cup whipped heavy cream. Each serving has 2.8 g net carbs. I use it to fill cheesecake bites, pipe it onto cupcakes, or serve it as a dip for berries.
I am obsessed with this recipe. It’s so quick and easy! I make a double batch of the vanilla version every weekend for desserts throughout the week, adding a tiny bit of real berries or sugar free preserves. Every time I ask my husband to pick up more cream cheese at the store, he knows I’m making more fluff!
Halfway through the fold I was sure I’d overworked it and it would go flat. It didn’t. Stayed light in the fridge overnight, which the other mousse-type ones I’ve made never do.
You can use a whisk, but whipping cold cream to stiff peaks by hand may take longer than the five-minute card estimate. An electric mixer makes the job easier.
Nothing about four ingredients and a mixing bowl should work this close to memory. I’d written off no-bake cheesecake as something that doesn’t translate to keto, but the lemon does more here than I expected, just enough bite to cut through the richness without tasting like sweetened cream cheese. It’s lighter than what I grew up eating (more mousse than the dense Cool Whip version from my mom’s kitchen), and I think that’s the whipped cream folded in thirds. Not quite the same thing, but close enough to surprise me.
Stir the first third of the whipped cream into the base, then fold in the remainder until evenly combined. Three passes is not a dependable count for every batch.
Making this for book club Friday, usually 10-12 of us, so I’m planning to triple it. Should scale straight across, I think, but I’m second-guessing the heavy cream. Large batches can get finicky when whipping. Do you recommend splitting into two separate bowls, or will triple the amount work in one go?
Scale the ingredient amounts for the number of portions you need. Whip in batches if the bowl is getting full, following your mixer capacity. Leave room for the cream to expand and fold gently afterward.
Coconut cream does not behave exactly like heavy dairy cream, and a dependable replacement for this fluff has not been established. Use heavy cream for the original method; the cream cheese also means this recipe is not dairy-free.
Four ingredients and it sets up without gelatin or thickeners, which most no-bake versions need. The 2.8 net carbs checks out too. Only thing I’d want is a bit more sweetener, but easy to adjust.
Start with the listed 1/4 cup powdered sweetener. If you adjust it, taste a small portion first and check the sweetness of your product. More sweetener can change the texture and nutrition.
Been making this every week since March, but last time I swapped the lemon juice for a tiny bit of lime and folded in fresh strawberries and now it’s the only dessert I want all summer.
That lime swap makes more sense for strawberries than lemon does, the tartness reads different against the berries. I haven’t tried that combo but I’m making it this week.
Made this with my daughter hovering the whole time asking to lick the beaters, and when she tried the finished fluff she goes ‘mom this is the cream cheese one, can we have it with strawberries every week.’ She has no idea it’s four ingredients and 2.8 carbs and I’m not telling her.
My daughter dipped into it before I even got out the berries, just a spoon straight from the bowl, and I think that’s actually the intended way to eat this. Lighter than I expected for something that’s mostly cream cheese.
Added a splash of vanilla to the cream cheese mixture on a whim and it pushed it over into actual cheesecake territory. I wasn’t sure if it would mess with the texture but it folds in fine. Four ingredients plus one is still basically no effort, and now I keep a batch in the fridge for when the 9pm sweet craving hits.
Vanilla can add a different flavor to the cream cheese base. Start with the directions for your extract and taste a small portion rather than treating another batch as a tested amount for everyone.
Never made anything like this before and I genuinely did not think four ingredients could taste this much like actual cheesecake filling but here I am eating it straight from the bowl with a spoon (okay, multiple spoons). The lemon juice is doing something I did not expect.
Ha, the bowl beats any presentation anyway. Try it after 30 minutes in the fridge next time – it firms up and the whole thing gets even closer to actual cheesecake filling.
Six batches in and I finally figured it out: stop folding two or three turns early. It goes from thick to actually airy and I got weirdly obsessed with how much that one thing changed it.
Fold until the mixture is evenly combined, then stop. The number of turns depends on the bowl and batch; there is not a fixed folding window that works for everyone.
First keto cheesecake I’ve made and honestly didn’t expect much from such a short ingredient list. That lemon juice in the cream cheese base really does something. Does it hold up overnight or does the cream start to weep?
Cover and refrigerate promptly. The texture can firm up or release a little moisture, so I would not guarantee no weeping. Keep berries separate until serving.
Berries in there are so good. One thing I’ve learned the hard way though: add them right before you eat it. Blueberries especially release juice and turn the whole fluff watery by morning.
