Let’s start a club.
The Peanut Butter Eaters Anonymous Club. In the club we’ll eat peanut butter straight from the jar. We’ll spread peanut butter on every piece of low carb chocolate we can find. And we will definitely, without a doubt, make this keto peanut butter mousse.
If you think you could be a member of that club, you’re going to want this recipe, because oh man. So good!
I’ve been enjoying making mousse lately, because it’s such a quick way to satisfy that craving for dessert.
My keto chocolate mousse and pumpkin mousse have been on repeat around here, so I thought I’d mix it up and throw some peanut butter at my next batch of mousse.
So rich and decadent with just a few minutes of work and a handful of ingredients!

Peanut Butter – You’ll want to look for a peanut butter that is sugar-free, if you’re strict keto. This creamy peanut butter is perfect. It’s 2 net carbs and the only ingredient is peanuts. If you’re just cutting carbs and not super strict, we really like Skippy with just 4 net carbs.
Sweetener: We like to use Lakanto monk fruit sweeteners. Their powdered sweetener is perfect for this recipe, since it won’t add the grainy texture of granulated sweetener. Swerve confectioners sweetener works too!
Peanut Butter Cups: These are totally not necessary, but how can you resist chopping up a peanut butter cup to sprinkle over the top of your mousse? We use Lily’s. Their chocolate candy is the best! (This post is not sponsored – just sharing what I love.)
Other – You’ll also need some heavy whipping cream and vanilla extract!
We use Thrive Market for a lot of our specialty ingredients and keto snacks or products. Their prices tend to be cheaper than the local stores and I love that you can so easily sort products by diet.
Like Costco, this is a membership site, but we find that it’s more than worth it based on the amount we save over the regular grocery store.
They have monthly or yearly plans. Check it out here.

How To Make Peanut Butter Mousse:
- Peanut Butter – Add room temperature cream cheese, peanut butter, powdered sweetener, and vanilla to a mixing bowl and use a hand mixer to beat that together until it’s thick and creamy.
- Whipped Cream – In a second bowl, add some cold whipping cream and beat with a mixer until stiff peaks form.
- Combine – Combine whipped cream into the peanut butter mixture with your mixer. You don’t want to overmix it, but you do want it to be all combined together.
- Serve – Spoon into a pretty serving bowl, top with some Lily’s peanut butter cups, and dive right in. This one is hard to resist!
Keto Mousse Toppings:
We like to top these with Lily’s Peanut Butter Cups but there are some other good options you could swap those with or just add to the mix!
- Chopped Nuts
- Sugar-Free Chocolate Chips
- Chopped Berries
- Shredded Coconut
- Chia Seeds
- Cocoa Powder
- Sugar Free Chocolate Syrup
Recipe FAQs:
You can keep this keto peanut butter mousse recipe stored in the refrigerator for about 4 to 5 days.
Although I have only tried this with peanut butter I’m sure you could swap it out for almond butter, cashew butter, or other varieties!

Peanut butter can be a great option on the keto diet, but be sure to read your labels and look for a peanut butter that doesn’t contain added sugars or unhealthy oils.

Hello Karly,
Is there a way I can convert the current ingredient list for the Keto Peanut Butter Mousse from 6 to 40? I would like to serve individual cups at a Christmas party.
Thank you

The easiest way would be to multiply the recipe by 7. You’ll end up with 42 servings.
