Ingredients
Method
- Soften the cream cheese. Set it out at room temperature for 30–45 minutes. This helps it whip smoothly and prevents lumps.
- Whip the cream. In a clean bowl, beat the heavy cream to soft peaks. Set aside. This adds lightness without baking.
- Cream the base. In a separate bowl, beat the softened cream cheese with the powdered sweetener until smooth and fluffy, about 2–3 minutes.
- Add the flavor. Mix in lemon juice, lemon zest, vanilla, and a pinch of salt. Taste and adjust sweetness and lemon to your liking.
- Fold in the whipped cream. Gently fold the whipped cream into the lemon cheesecake base until just combined. Don’t overmix.
- Layer the berries. Divide half the blueberries among your cups. Spoon in the cheesecake mixture, then scatter the remaining blueberries on top. Press lightly so they set into the cream.
- Chill to set. Refrigerate for at least 45–60 minutes, or up to 24 hours. The texture will firm up and become velvety.
- Garnish and serve. Add a little extra lemon zest and a few blueberries on top before serving for a fresh finish.
Overeating is a pattern. This helps you fix that problem. A quick reset for cravings, snacking, and “I’ll start tomorrow” moments.
Built for busy home cooks who want real-life structure. Simple steps that fit meal prep, family dinners, and late-night snack attacks.
Why This Recipe Works
These cheesecake cups skip the crust, which keeps the carbs low and the prep fast. Lemon brightens the creamy filling and balances the sweetness from the berries and sweetener.
Using full-fat cream cheese and heavy cream creates that classic cheesecake texture without baking. The berries add natural sweetness, fiber, and color without sending carbs soaring. Everything comes together in one bowl and sets in the fridge in under an hour.
What You’ll Need
- Cream cheese: 8 ounces (full-fat), softened
- Heavy whipping cream: 1/2 cup

- Fresh lemon juice: 2 tablespoons
- Lemon zest: 1 teaspoon (from 1 lemon)
- Vanilla extract: 1 teaspoon
- Fresh blueberries: 1 cup, divided
- Pinch of salt: optional, for balance
- Optional garnish: extra lemon zest or a few blueberries on top

Keeping It Fresh
These cups keep well in the fridge for 3–4 days. Cover them tightly to prevent the cream from picking up fridge odors.
If you’re prepping ahead, add the blueberries on top just before serving for the best texture. For a longer hold, freeze the cups without berries for up to 1 month. Thaw in the fridge overnight, then add fresh berries and zest.
Why This is Good for You
This dessert keeps carbs low while delivering satisfying fats that align with a keto lifestyle.
Cream cheese and heavy cream provide satiety, which helps reduce cravings for high-carb sweets. Lemon adds vitamin C and a bright flavor that lets you use less sweetener. Blueberries, used in moderation, offer antioxidants and fiber without spiking carbs too high.
It’s a good example of how you can enjoy dessert while staying on track.
Common Mistakes to Avoid
- Using cold cream cheese. Cold cream cheese won’t whip smoothly and can leave lumps. Let it soften first.
- Overmixing the whipped cream. If you beat to stiff peaks or fold too aggressively, the texture can turn grainy.
- Adding too much lemon juice. Too much liquid can loosen the mixture. Balance juice with zest for strong lemon flavor.
- Choosing the wrong sweetener. Granulated sweeteners can feel gritty.
Use a powdered keto sweetener for a smooth finish.
- Skipping the chill time. The cups need time to set. Serve too soon and they’ll be soft and less creamy.
Variations You Can Try
- Almond crumble base: Press a quick mix of almond flour, melted butter, powdered sweetener, and a pinch of cinnamon into the bottom of each cup for a no-bake “crust.” Keep portions small to stay low-carb.
- Greek yogurt boost: Swap 2–3 tablespoons of the cream cheese with full-fat Greek yogurt for a tangier bite and extra protein.
- Different berries: Raspberries or blackberries work well and are naturally lower in carbs. Use the same amount.
- Meyer lemon or lime: Change the citrus profile by using Meyer lemon or lime juice and zest for a gentle or sharper citrus note.
- Lemon curd swirl (keto): Spoon in a ribbon of keto lemon curd for an elegant finish.
Keep it light to manage carbs.
- Protein boost: Fold in a scoop of unflavored or vanilla whey isolate. Start with half a scoop and adjust liquid if needed.
- Dairy-free option: Use a dairy-free cream cheese and whip full-fat coconut cream. Flavor with extra zest to balance the coconut.
FAQ
Can I use frozen blueberries?
Yes, but thaw and drain them well first.
Pat dry to avoid streaking the cream and adding extra moisture that can soften the texture.
What sweetener works best?
Powdered erythritol or allulose blends work best for a smooth texture. Allulose tends to be less cooling and melts more cleanly, but you may need a touch more to reach the same sweetness.
How many carbs are in each cup?
It varies with portion size and sweetener brand, but most versions land around 4–6 net carbs per serving when divided into 6–8 cups. Check your exact ingredients and serving sizes to be sure.
Do I have to whip the cream separately?
It’s best.
Whipping the cream first adds volume and a lighter texture. If you skip this step, the cups will be denser, more like a traditional no-bake cheesecake.
Can I make this ahead for a party?
Absolutely. Make them the day before, cover, and chill.
Add fresh berries and zest just before serving for the best look and bite.
What if I don’t have a mixer?
You can use a sturdy whisk. Soften the cream cheese thoroughly and whisk the heavy cream until it thickens. It takes a bit more elbow grease but still works.
How tart should it be?
That’s up to you.
For a brighter lemon pop, use the full zest and juice and start with less sweetener. For a milder flavor, add more sweetener and reduce the juice slightly.
Final Thoughts
Keto Lemon Blueberry Cheesecake Cups make dessert simple, satisfying, and low-carb without sacrificing flavor. They’re creamy and bright, with just enough sweetness and a pop of berry in every bite.
Keep a batch in the fridge for an easy treat or dress them up for guests with a little zest and a few fresh berries. This is the kind of recipe that fits your routine and feels special every time you make it.
