Keto Lime Protein Mousse
Ingredients — 2 large servings
- 200 g full-fat cream cheese — softened
- 100 ml heavy whipping cream
- 30 g unflavored or vanilla whey protein isolate — choose one with 0–1 g carbs
- 1–2 tbsp lime juice — for strict keto, use less
- 1 tsp finely grated lime zest
- Liquid stevia or sucralose — to taste
- ¼ tsp vanilla extract
- Pinch of salt
- Optional topping: crushed pecans/walnuts, but these add carbs
Method
- Beat the cream cheese until completely smooth.
- Add whey protein, sweetener, vanilla and salt.
- Slowly add the heavy cream while mixing.
- Add lime juice and zest.
- Whip for another 1–2 minutes until thick and fluffy.
- Refrigerate for 30–60 minutes.
- Layer into a cup like the picture.
- Finish with a little lime zest.
🔥 For the lowest possible carbs
Skip:
- Graham crackers
- Cereal
- Regular condensed milk
- Sugar
- Honey
- Banana
- Most commercial whipped toppings
For the crunchy layer in the picture, use finely chopped pecans or walnuts rather than cereal/crackers. But remember that nuts aren’t zero-carb either.
Approximate nutrition
Using 200 g cream cheese + 100 ml heavy cream + 30 g whey isolate, divided into 2:
| Per serving | Approx. |
|---|---|
| Calories | 350–400 kcal |
| Protein | 18–22 g |
| Fat | 30–35 g |
| Total carbs | ~4–6 g |
| Net carbs | ~3–5 g |
Important: exact numbers depend heavily on the brands you use.
If your goal is strictly 0 g net carbs, I can also give you a zero-sugar, zero-carb-style lime dessert using protein isolate + fat, designed to stay as close to 0 g net carbs as realistically possible.
Zero-Carb / Keto Lime Mousse — Q&A
Q: Is this really zero carb?
A: Not literally. Dairy, lime juice, and protein powder can contain small amounts of carbs. You can make it extremely low-carb, but true 0 g requires carefully selected ingredients and label verification.
Q: Can I make it without sugar?
A: Yes. Use stevia, sucralose, or another zero-calorie sweetener.
Q: Can I use lime juice?
A: Yes, but lime juice contains some carbohydrates. For the lowest-carb version, use lime zest plus a small amount of juice.
Q: Can I use lemon instead?
A: Yes. The same principle applies—use zest for strong flavor and keep the juice modest.
Q: Can I use Greek yogurt?
A: You can, but yogurt contains lactose, so it will generally add more carbs than cream cheese and heavy cream.
Q: What protein powder is best?
A: Whey protein isolate is usually a good choice because many varieties are very low in carbohydrates. Check the nutrition label rather than assuming all whey powders are low-carb.
Q: Can I make it without protein powder?
A: Yes, but the protein content will be considerably lower.
Q: What can I use for the crunchy topping?
A: Pecans or walnuts work well. However, nuts are not zero-carb, so omit them if you’re targeting the lowest possible carb count.
Q: What about the cereal-looking topping in the photo?
A: Avoid regular cereal, granola, cookies, or graham crackers if you’re trying to keep carbs extremely low. They can add substantial carbohydrates.
Q: Can I make it high protein?
A: Yes. Add whey isolate and adjust the amount according to your protein target. A serving can reach roughly 20 g protein depending on the ingredients.
Q: Can I make it dairy-free?
A: Yes, but you’d need to replace the cream cheese and heavy cream with suitable unsweetened, low-carb alternatives. The nutrition will change.
Q: How long does it keep?
A: Keep it covered in the refrigerator and preferably consume it within 2–3 days.
Q: Can I freeze it?
A: You can, but thawing may make the texture less smooth. Refrigeration gives the best mousse consistency.
Q: How do I make it taste more like the dessert in the picture?
A: Use plenty of lime zest, a little lime juice, vanilla, sweetener, and a small amount of finely chopped pecan or walnut for texture.
Q: What makes it thick and fluffy?
A: Whipping the heavy cream and thoroughly beating the cream cheese creates the mousse-like texture. Chilling it afterward makes it firmer.
Q: Is this keto-friendly?
A: It can fit a keto diet when made with low-carb ingredients, but the actual net carbs depend on your specific brands and quantities. Check the labels of the cream cheese, protein powder, and sweetener.
