I am a peanut butter lover. Once I went to a family dinner and someone made a peanut butter pie that I still think about it. That is why I decided to make this easy keto peanut butter mousse recipe for our Valentine’s Day dinner.

II should have made something my husband would like but I’m the one with the sweet tooth so I thought he would forgive me. 🙂 This keto dessert is super easy to make and I even put a little chocolate heart for some Valentine’s Day decoration.  

They are small but SUPER filling and have only 3.5g net carbs. So if you are on a low carb or keto diet and love peanut butter flavor, this is the dessert for you. Plus you can make this in 5 minutes and with just 4 ingredients so you can’t beat that.

Recipe ingredients and substitutes.

The 4 simple ingredients you need to make this keto dessert is peanut butter, sweetener, cream cheese and heavy cream. Originally when I made this I also used a keto friendly peanut butter powder but I found it’s not necessary. 

Creamy Peanut Butter
You want to use a natural, keto friendly peanut butter that only uses peanuts. So no sugar added types are best to keep the carbs down. I found this Crazy Richard’s brand at my local grocery store and it only had 4 grams of carbs per 2 tablespoons.

Just read the labels and pick the brand that has the least net carbs. This Teddie brand also only has 4g but I have not tried it. If you have peanut allergies you can substitute with almond butter, cashew butter or any other nut butter you like. I like sunflower seed butter sometimes as a good substitute for peanut butter.

Heavy Cream and Cream Cheese
You want to use full fat cream cheese if you on a low carb or keto diet. Sometimes the lighter versions have a higher carb count. And for the cream I would suggest heavy whipping cream. Even with these two common ingredients the number of carbs vary by brand.

Normally I suggest using coconut cream instead of heavy cream in many of my low carb recipes however I’m not sure if it can be whipped. It might be worth trying though if you are  dairy free.

Sweetener
I love Swerve sweetener and usually buy the confectioners powdered sweetener. Since this is a no bake dessert the keto powdered sugar mixes well. You can use any brand of your favorite sugar substitute. It can also be a granulated sweetener if that is all you have.

If you want to you can add vanilla extract. Just use ½ teaspoon vanilla if you do. Also if you want to garnish with the chocolate hearts just scroll down to learn what type of keto friendly chocolate to use. 

How to make keto peanut butter mousse.

Step 1: To a medium mixing bowl add the softened or room temperature cream cheese and sweetener. Using an electric mixer, blend until the both combine and have a fluffy texture It should be smooth and creamy. It might not seem like it’s going to come together but it will.

Step 2: Add the peanut butter to the bowl and mix. Then add the heavy cream. Beat this for a few minutes until the texture is a thick and creamy mousse and soft peaks form.

Step 3: Spoon the mixture into a piping bag or even and ziplock baggie with the corner cut off. Pipe into small dessert dishes and refrigerate until ready to eat.

How to make this keto friendly chocolate hearts.

These chocolate hearts are really easy to make. The delicious flavor of chocolate of course goes great with peanut butter.  You can see the photos below of how I did it.

1. Take half of the small Moser’s dark chocolate bar and melted in the microwave for about 1 minute. Take it out and mix it well until everything is melted. You can also use low carb chocolate chips. See below.
2. Then on a wax paper covered baking tray use a little spoon and put a little dollop on the wax paper.
3. Then taking the spoon and push the melted chocolate up on the sides and then dragged the bottom down to form a heart.
4. Freeze them for 5 minutes and you are good to go!

What type of chocolate should you use?

I like these Moser 85% dark chocolate bars that I get at Aldi. Each little bar like the one below has only 6 net carbs. I used ½ of the bar and got 4 hearts made. So that means each heart has roughly 0.8g net carbs.  You can use any chocolate you want but remember to count the carbs.

Below you can see that I also shaved the chocolate with a peeler and this makes a nice garnish too.

You can also use keto friendly chocolate chips too. You can melt them instead of the candy bar to make the hearts, mix them in or use them as a topping. I’ve used Swerve sugar free chocolate chips or Lily’s chocolate chips because they are low in carbs.

However you can use any keto or low carb chocolate you want.

If you want you can pipe this keto peanut butter mousse into a little dessert glass.  I used to use 4 oz mason glass jars but my husband took all of mine for his homemade chili powders. The ones below are 3.5 ounce dessert glasses. I found these on Amazon that are similar. 

Refrigerate these until you are ready to eat them and they keep for a few days. My batch made 4 of this size, so use that as a guide for your containers. Remember they are very rich and filling so less is more.
