Peanut Butter Mousse Recipe

Utterly decadent and delicious, this velvety smooth dessert is always a hit any time you like!

Calling all peanut butter lovers! Get ready for a delicious treat when you prepare this peanut butter mousse recipe for dessert. It is so rich, creamy, and peanutty that you may not be able to stop at one serving. But, since nut butter is rich in protein, I tell myself that it’s ok to indulge in this yummy dessert on occasion.

I love peanut butter, although lately my go-to is almond butter. However, I have fond memories of existing on peanut butter and strawberry jam sandwiches when I was pregnant with my second child, my daughter. In fact, I often joke that I ate so much peanut butter back then that it’s no surprise she didn’t like it at all until she was almost an adult. The funny thing is that I ate a lot of tuna sandwiches with child number one, and he still won’t eat the stuff as an adult. I’m curious if anyone else has experienced anything like that.

Now that I’ve digressed a bit, let’s get back to discussing why you’ll love peanut butter mousse as much as I do. First, it’s so light and fluffy you’ll feel each delectable bite just melt away on your tongue. Next, it’s incredibly easy to make, and you can enjoy it right away. There’s no need to boil water for gelatin or use a double boiler and eggs. This recipe doesn’t need any of that. So, even if you didn’t plan anything for dessert or want a quick treat, it takes only five minutes to go from start to finish. A hand mixer and a spatula are all you need. How’s that for an easy dessert?

If you like your mousse a bit thicker, I recommend refrigerating it for at least 30 minutes, though I like to let it chill for a few hours before serving. It’s also a great make-ahead dessert. Once you’re ready to enjoy this creamy treat, grab your spoon and tuck into every sweet-and-salty delicious bite.

Customizations, substitutions, and other fun ideas

There is so much that you can do with this recipe to make it your own. First, any nut or seed butter will work, which is great if you are concerned about anyone with peanut allergies. You can also go dairy-free by using plant-based cream cheese and heavy cream. Powdered sugar substitutes are just as easy to use. Also, if you don’t have any powdered sugar on hand, it’s easy to make by following our recipe for How To Make Powdered Sugar. I use this recipe as a guideline for making it with date, maple, or coconut sugar and tapioca starch. The amounts are the same: two cups of your chosen sugar to two tablespoons of tapioca starch or flour.

As for some other fun ideas, feel free to fold in or top the mousse with some chocolate, butterscotch, white chocolate, or even peanut butter (can you ever have enough peanut butter?) chips. You can also add crushed peanuts, cookie crumbs, and chocolate shavings.

How do I store leftovers?

Although I doubt it will last that long, you can store this peanut butter mousse in the refrigerator for up to 5 days. I cover the mousse with plastic wrap to help preserve its freshness. While it will become denser in the fridge, removing it at least 15 minutes before serving will help lighten the texture. You can freeze the mousse for up to 2 months by placing it in an airtight freezer container or tightly covering it with plastic wrap. Defrost it overnight in the refrigerator before serving.

Serving suggestions

There are so many ways to enjoy this peanut butter mousse, but I think my all-time favorite is to make a layered parfait with this Chocolate Mousse Recipe and a dollop of Chocolate Whipped Cream on top. Or, if like me, you love the combination of peanut butter and strawberry, layer this Strawberry Mousse Recipe with the peanut butter mousse and this Strawberry Whipped Cream Recipe. Or go all out and make this Tart Crust Recipe, and fill it with the mousse. Top it with assorted berries for a deliciously decadent dessert.
