Three Ingredient Peanut Butter Mousse

This easy Three Ingredient Peanut Butter Mousse recipe is perfect as a layer for trifles, as a filling for cakes, as a cookie/cracker dip, or even served with celery.

The best three ingredient peanut butter mousse recipe made with cool whip/whipping cream instead of cream cheese.

If you like a good mousse and are a fan of peanut butter, you are going to be in HEAVEN over this easy recipe that I have created.

Easy Peanut Butter Mousse

It’s easier than you may think too. The best part is that it takes a mere two or three minutes to throw together and only calls for three ingredients that you easily may already have on hand…at least if you do any baking on a regular basis.

I based this recipe off of this awesome Vegan one by Dana over at, so if you want the crunchy/clean eating version of this, make sure to head on over to her site.  

Mine is just a very unhealthy version of hers and it also is a large enough batch to use the whole tub of whipped topping.

I actually had no intention of turning this recipe into a post on its own. I was developing a Moose Tracks Trifle recipe and this peanut butter mousse I made for two of the layers turned out so tasty that I just had to share it on its own too.

Anyway, I apologize if the photography is not the greatest…I just couldn’t justify hiring someone to take pics of a three ingredient recipe that take a couple of minutes to make…so you get to deal with my mediocre photography and staging skills.

Let’s just dive right in, learning how to make Peanut Butter Mousse:

Like I said, it’s just three easy ingredients and you may very well already have them on hand.

You literally just plop the ingredients into a large mixing bowl…(the bowl I used is four quarts)

Then mix until well incorporated… it’s so easy even a second-grader could make this mousse.

Three Ingredient Peanut Butter Mousse

Peanut butter mousse made with cool whip/whipped topping.

Mousse can be used as a filling between cake layers, in a trifle, or as a dip for crackers, cookies, or celery.

Prep Time 3 minutes
Additional Time 2 minutes
Total Time 5 minutes


  • 1 (16 oz) Tub Whipped Topping (thawed)
  • 1 C Peanut Butter
  • ½ C Powdered Sugar


    1. Scoop all ingredients into a medium to large bowl.
    2. Stir until well mixed and smooth.
    3. Cover and refrigerate. Mix well before serving.


If serving as a dip, it can easily be staged by putting it in a piping bag and squirting it into individual containers and garnish with Nutter Butters.

This recipe makes two layers if used in a trifle.

Easy peasy and this recipe will probably end up being your go-to recipe any time that you want to make a Peanut Butter Mousse in the future… it’s that good!

I could literally sit down and eat it straight, but it is best to eat it sparingly…otherwise your tastebuds are going to love me but your butt and thighs are going to be sending me hate mail very soon and we can’t have that, can we?

I hope you like it as much as my kids and I do. Please make sure to share it via social media if so…or you could even send your friends a direct link via email ;).
