You might notice that I don’t share a ton of peanut butter recipes here on my blog. It’s because my oldest son has a peanut allergy, so I usually don’t keep peanut products at our house. Once a month, though, I try to make something easy with peanut butter for my other two kiddos. This is to prevent them from developing an allergy due to avoidance.

They LOVED this Peanut Butter Mousse and literally devoured it! It was super easy to make and I plan to try it with cookie butter next time so my allergy kiddo can try it, too.

How to Make Peanut Butter Mousse – Step by Step

A full list of ingredients, measurements, and instructions are located in the recipe card below.

Step 1: Make Oreo crumble

Divide the crushed Oreos between 4 or 6 small jars. If using 4 jars, the mousse will yield 3/4 cup each. If using 6 jars, the mousse will yield 1/2 cup each.

Step 2: Combine cream cheese and peanut butter

In a large bowl, beat together the softened cream cheese and peanut butter with an electric mixer on medium speed until well combined. 

Step 3: Add powdered sugar

Gradually add the powdered sugar followed by the vanilla, beating on low speed. 

Step 4: Add heavy cream

When all of the powdered sugar has been incorporated, slowly beat in the heavy cream over low speed. Gradually increase the speed of the mixer as the heavy cream incorporates– you don’t want to splash the cream everywhere. Continue mixing on medium speed until the mousse is light and fluffy– about 4 minutes. Make sure to scrape down the sides of the bowl as needed. 

Step 5: Serve

Divide the peanut butter mousse between the jars and place in the fridge to chill for at least 1 hour before serving (this will help solidify the mousse). 

Tips and Notes for making The Best Peanut Butter Mousse

• Oreo substitute: I’m using Oreo crumbs to make the cookie crust but you could use chocolate graham crackers or another kind of cookie, or leave the crumble out entirely. 
• Use softened cream cheese. Cream cheese adds richness and tang to the mousse. Make sure it’s fully softened or you’ll end up with lumps in your peanut butter mousse. 
• What kind of peanut butter to use: I recommend a classic creamy peanut butter (not an all natural brand) as all natural peanut butter tends to be wetter and results in a softer mousse. 

Storing and Freezing

Any leftover peanut butter mousse can be stored, covered, in the refrigerator for up to 4 days. It can also be frozen! To freeze, place in a freezer safe container or freezer Ziploc bag and store in the freezer for up to 3 months. Thaw in the fridge before serving. Storing individual servings in the freezer makes it easy to grab a quick dessert whenever the mood strikes!
