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 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!

Products Used:

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, we really like Skippy with just 4 net carbs.

Sweetener: We use and love Lakanto products. Their powdered sweetener is perfect for this recipe, since it won’t add the grainy texture of granulated sweetener. Use code THATLOWCARBLIFE for 20% off your order!

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!

Thrive Market: You may have noticed that a few of those links are for Thrive Market. We are obsessed with that shop – it’s similar to Costco in that it’s a membership site and you get a cheaper price on products. Beyond that, though, we love how easy it is to shop there.

You can sort by dietary needs and you won’t see all the extra stuff you don’t want.

Their keto section is phenomenal. I just looked and they have 733 keto products currently! Amazing!

They have different membership options available, ranging from monthly to yearly, so go check them out! The prices are great and we always save more than we spend on the membership.

How to:

This recipe is quick and simple!

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.

In a second bowl, add some cold whipping cream and beat with a mixer until stiff peaks form.

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.

Spoon into a pretty serving bowl, top with some Lily’s peanut butter cups, and dive right in.

This one is hard to resist!

    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.
