Ingredients You'll Need
Peanut butter lovers get ready to jump for joy. Soft and buttery, a bowl of mousse is always a crowd-pleaser, and this keto peanut butter mousse is the perfect example. Sweet and comforting, earthy and light as air, it’s the kind of dessert that one generous spoonful will put a big smile on your face.
Besides being the perfect keto pick-me-up, it can also be used as frosting for your favorite keto cakes or pie and tart filling. Serve it in a wine or Martini glass for a nostalgic 90s vibe. Here's what you'll need to make it:
- Heavy Whipping Cream: Rich heavy whipping cream is part of the base of the mousse, bringing a thick texture, light color, and subtle sweetness. When whipped, the cream becomes fluffy and light which is the optimal texture of the mousse.
- Cream Cheese: Alongside whipping cream is cream cheese, a tangy flavored ingredient thickening the mousse to help it become silky smooth. Allowing the cream cheese to soften to room temperature will make it easier for the blender to do so, so remove it from the refrigerator an hour or so before you plan to make the mousse.
- Peanut Butter: Peanut butter flavors take center stage with this mousse, and to keep things keto-friendly, it’s best to use natural, unsweetened peanut butter. Using smooth peanut butter keeps it in line with the other ingredients, which are all smooth and silky, so there are no lumps in the final mousse.
- Low Carb Sugar Substitute: A powdered low-carb sugar substitute is the perfect sweet addition to the mousse, as it blends well and doesn’t leave any bits or lumps behind. Instead, the powdered sugar replacement brings a light sweetness that doesn’t take away from the natural earthiness of the peanut butter or delicate vanilla flavor.
- Vanilla Extract: Vanilla adds sweetness to the mousse, but it also lightens the overall flavor, uniting ingredients together in the dessert. High-quality unsweetened vanilla extract is an ideal choice as it has a well-rounded vanilla flavor that isn’t sweetened by glucose syrup, sugar, or artificial flavorings.
- Salt: A sprinkling of salt in sweet recipes helps bring balance and enhances the flavors within the mousse. Salt helps bring out the nutty peanut butter notes and uplifting notes of vanilla, just be sure to only add a small amount to avoid making an overly salty mousse!
How To Make Keto Peanut Butter Mousse
Our keto peanut butter mousse is effortless, with an electric blender doing most of the hard work. Containing familiar ingredients and requiring just 10 minutes of prep time, our mousse recipe is one to keep on standby when the sweet cravings hit or you need a family dessert this weekend. Let the kids enjoy the fun by garnishing the mousse with their favorite topping, such as grated dark chocolate, chopped peanuts, or shredded coconut.
- Using an electric blender, beat the whipping cream for 3-5 minutes until it doubles in size and holds firm peaks. Set aside, preferably in the fridge, until the other ingredients are ready to be incorporated.
- Whisk the cream cheese, peanut butter, powdered sweetener, vanilla extract, and a pinch of salt together until combined.
- Remove the whipped cream from the refrigerator and fold the cream cheese mixture into the cream with a spatula until all the ingredients have united with no streaks of peanut butter or cream.
- Serve immediately for a soft mousse texture, or refrigerate for 1-2 hours so the mousse can set even more. Serve cold alone or garnish with simple low-carb toppings.
Storage Tips
In the fridge: Any leftover mousse will keep in the fridge for up to 4 days. Make sure you keep it in an air-tight container.
In the freezer: You can freeze this mousse, which will keep for up to 2 months. Just place it in the fridge to let it thaw, and make sure you don't try to heat it in any way.
Recipe Variations
Keto Peanut Butter and Chocolate Mousse: For a chocolatey boost to the mousse, add a tablespoon of cocoa powder to the cream cheese mixture before blending. Once incorporated, the cocoa powder will darken the color of the mousse and bring a hit of mouthwatering chocolate flavor. Garnish with a final light dusting of cocoa powder for a gorgeous and tasty finish.
Piping Bag Mousse Tip: Once completed, the mousse can be served however you like, but using a piping bag is an effective way of upping your presentation game. Fill a piping bag with the mousse and either cut the corner of the bag or use a nozzle to decant the mousse into ramekins. This gives such an effective finish, especially when serving the mousse at a family holiday or dinner party.
Keto Layered Peanut Butter Mousse: Layering the mouse with a spoonful of peanut butter between each layer is the dream for nut lovers. When using clear glasses or jars, layering the mousse with peanut butter creates a gorgeous finish of light creamy mousse and sand-colored nut butter.
Frequently Asked Questions
How Many Carbs Are In Keto Mousse?
Our keto peanut butter mousse recipe contains 2.5g of net carbs per serving. By omitting sugar and using a low-carb substitute for sweetness instead, it’s easy to keep this mousse recipe low-carb.
Why Is My Mousse Not Setting?
If your mousse isn’t firming up and setting after spending a couple of hours in the refrigerator, you may have under-whipped the heavy cream. It needs to be whipped until soft peaks form, and it begins to hold its shape.
Why Is My Mousse Grainy?
Overmixing the heavy cream can lead to a grainy mousse, so it’s important to find the balance of a stiff cream that’s perfectly whipped and not overwhipped. Aim to whip the ingredients until they thicken. This should only take a short amount of time with a hand spatula combining the ingredients together gently.

Can you use Monk fruit sugar in place if the Erylritol?
Yes, you can use any sugar-free sweetener 🙂
My husband loves peanut butter! I can’t wait to make this for him. Good thing I read through your whole text—the first time you list the ingredients it says 1 tsp of salt. As I read on you say to add a pinch of salt, and the recipe card at the bottom states 1/4 tsp.of salt. I thought you might want to know so you could correct it.
Hi Debra, thanks for pointing that out! I've fixed the recipe 🙂 Hope your husband enjoys the recipe!
Can you make this with stevia instead of erithytol? And can you use pb2?
Hi Jana, yes you can use both stevia and pb2 in this recipe!
Hi Jennifer, I would like to know if monkfruit is ok to substitute on the sweetener.
Hi Lillian, you can definitely use monkfruit instead of Erythritol in this recipe!
Hi Jennifer, thanks so much for this amazing yet simple recipe. Absolutely delicious. I have a question though: Does it freeze well? If it’s in the fridge, how long can you keep it for?
Thanks again.
Hi Vuyo, thank you for the kind words 🙂
You can freeze the mousse for up to 2 months, just make sure you put it in the fridge to thaw and don't try to heat it in any way. You can also keep it in the fridge for up to 4 days in an air tight container.
Hope that helps!
Hello. I made this for my day one of my keto journey. My question is it’s so fulling can I eat half and leave e rest for tomorrow for my next snack??
Hey Roxy, yes you can definitely keep it in the fridge covered for tomorrow 🙂
I hate PB so I used almond butter instead and it was still SO good! Is the serving portion correct for the macros? It says 1 cup per serving and 6 servings per recipe but what I made definitely wouldn’t serve 6 at that portion. Thanks!
This was amazing! Definitely will be making again, the serving size says 1 cup and it says it makes 6 servings using one cup makes barely two servings just wanted to point out
The top of the nutrition information on the recipe card says 2.5 net carbs but at the bottom when it is giving all the other nutritional information, it says 3.5 net carbs. I’m not sure is is 2.5 or 3.5 net carbs?
Hi Trish!
Sorry for the typo. The correct net carb count is 2.5 grams.
First lemme say that this mousse tastes amazing!
... But the calories are not correct. The calories are listed as 311 for 2 servings. When I carefully plug all the ingredients into MyFitnessPal, I can only get it down to 334 calories for 3 servings.
Can this be made with Almond Butter in place of the Peanut Butter?
Hi Ralph, yes it can!
Awesome as we have a peanut allergy issue in the house. Thank you.
