Ingredients You’ll Need
For the Base Mousse:
- 8 oz cream cheese, softened
- 1/2 cup natural peanut butter (no sugar added)
- 1/2 cup heavy whipping cream
- 3-4 tbsp powdered erythritol (or your preferred keto sweetener)
- 1 tsp vanilla extract
- 1/4 tsp salt
Optional Toppings:
- 2 tbsp sugar-free chocolate chips
- 1 tbsp chopped peanuts
- 1 tbsp unsweetened shredded coconut
- A sprinkle of cinnamon
- A drizzle of sugar-free chocolate sauce
Step-by-Step Instructions
Step 1: Prepare Your Ingredients
Allow the cream cheese to soften at room temperature for about 30 minutes. Measure out all remaining ingredients so they’re ready to go. This quick prep ensures your mousse comes together smoothly without any clumps.
Step 2: Whip the Base
In a large mixing bowl, combine the softened cream cheese and natural peanut butter. Use an electric mixer on medium speed to beat until completely smooth and well incorporated, about 2 minutes. Make sure to scrape down the sides of the bowl occasionally.
Step 3: Add Sweetener and Flavorings
Add the powdered erythritol, vanilla extract, and salt to the peanut butter mixture. Beat again until everything is well combined and the sweetener is fully dissolved, about 1 minute. The mixture should look smooth and slightly fluffy.
Step 4: Whip the Cream
In a separate bowl, whip the heavy cream until stiff peaks form, about 3-4 minutes on high speed. You’ll know it’s ready when the cream holds its shape when you lift the beaters.
Step 5: Fold Everything Together
Using a rubber spatula, gently fold the whipped cream into the peanut butter mixture. Use a light hand and fold just until combined – overmixing will deflate the mousse and make it dense rather than airy.
Step 6: Portion and Chill
Divide the mousse into individual serving containers (small ramekins, mason jars, or dessert cups work great). For the best texture and flavor, refrigerate for at least 1 hour before serving, though you can enjoy immediately if you can’t wait!
Step 7: Add Optional Toppings
Just before serving, sprinkle with your choice of toppings for added texture and visual appeal. A few sugar-free chocolate chips, chopped peanuts, or a light dusting of cinnamon can elevate this simple treat to something special.

Pro Tips for Success
- Choose the right peanut butter: Look for natural peanut butter with just peanuts and salt listed in the ingredients. Avoid brands with added sugars or hydrogenated oils that can add unwanted carbs.
- Sweetener tips: Powdered sweeteners blend much better than granulated ones. If you only have granulated sweetener, pulse it in a blender or food processor first to create a finer texture.
- Texture troubleshooting: If your mousse seems too runny, refrigerate it for 30 minutes to allow it to set up. If it’s too firm, let it sit at room temperature for 5-10 minutes before serving.
- Make ahead strategy: This mousse actually tastes better when made a day ahead, as the flavors have time to meld. Perfect for meal prep!
- Temperature matters: Make sure your cream is very cold for the best whipping results, but your cream cheese should be room temperature to avoid lumps.

Almond Butter Alternative
Substitute the peanut butter with unsweetened almond butter for a slightly different flavor profile and potentially fewer carbs.

Top 4 FAQs About Keto Peanut Butter Mousse
Is this keto peanut butter mousse truly keto-friendly?
Yes! With only 4g of net carbs per serving, this dessert fits perfectly within keto macros. The high fat content from cream cheese, heavy cream, and peanut butter helps keep you satisfied without spiking blood sugar.
Can I make this mousse dairy-free?
Absolutely! Substitute the cream cheese with dairy-free cream cheese alternative and replace heavy cream with chilled full-fat coconut cream (the solid part from a can of coconut milk). The texture will be slightly different but still delicious.
How can I make this peanut butter mousse sweeter without adding carbs?
If you prefer a sweeter mousse, you can add an additional tablespoon of powdered erythritol or a few drops of liquid stevia. Both options add sweetness without increasing the carb count significantly.
Can I use crunchy peanut butter instead of smooth?
Yes! Using crunchy peanut butter will add texture to your mousse. Just be aware that the final texture won’t be as smooth, but many people enjoy the little bits of peanut throughout the mousse.
