This easy chocolate mousse filling is light, fluffy, and can be whipped up in minutes. 

We have used it in several of our cakes, including our Easy Chocolate Mousse Cake! If you are looking for a quick, easy, and delicious chocolate cream filling, this is the one.

How to Make Easy Chocolate Mousse Filling with Pudding and Cream

We often refer to this delicious chocolate cream filling as a mock mousse because unlike a traditional mousse, this filling is made with just two ingredients: instant chocolate pudding & heavy cream.

Nobody would ever guess how quick and easy this recipe is.  It comes together in minutes (but that will be our little secret!)

  • To make this recipe, you simply need a box of Instant Chocolate Pudding and heavy cream. Rather than making instant pudding the usual way with milk, the heavy cream makes it much thicker, creamier, spreadable and even pipeable (you can see an example of this in our Butterscotch Cake).
  • The resulting chocolate cream has the consistency of mousse rather than pudding, and the best part is that it all comes together in minutes.

We like to use a hand mixer to mix it up for convenience.

What if the Mousse Filling is too thick?

After mixing together the pudding and cream in your mock mousse filling, you may find that the consistency is slightly thicker than expected. If this happens, simply add a little more heavy cream and mix a little longer until you are happy with the consistency.

Delicious Chocolate "Mock Mousse" recipe by My Cake School. Amazing filling for chocolate cakes and cupcakes!

This luscious chocolate cream filling has wonderful chocolate flavor without being overly rich. (In other words, I could EASILY get carried away and eat the whole bowl myself!)

We love this as a light filling in our chocolate cakes or injected into chocolate cupcakes.  

Do you need to Sift Instant Pudding Mix?

While you do not need to sift instant pudding mix before using, I find that it results in a smoother consistency. Have you ever had a bite of pudding and noticed a little hardened piece of sugar that didn't dissolve? Ugh! 

The fix for this is sifting. You'll notice when you sift pudding mix that often several little hardened granules will remain in the sifter. Just toss them in the sink- we don't want them in our pudding ;0)

I sift my cake mixes as well!

Other Variations of this easy mousse filling

We have used this Mock Mousse technique in several of our FAVORITE cake recipes. For example, our Orange Dreamsicle Cake has a delicious Orange Cream Filling which is made from vanilla pudding, cream, and orange extract. 

We have also used a variation of this filling to make our Pineapple Cake Recipe with an amazing Pineapple & Cream Filling, as well as our Peaches and Cream Cake recipes!! Both of these variations contained bits of fruit in the vanilla mousse filling! Yum!!

Our Scratch Butterscotch Cake Recipe   is also filled and topped with a Butterscotch Cream filling and topping which is based on this recipe.

When it comes to mock mousse fillings, the options are endless. You can experiment with different flavors of pudding, add in extracts, stir in mini chocolate chips, fruit, or coconut. Have fun experimenting!

Chocolate "Mock Mousse" Filling

This easy chocolate mousse filling can be whipped up in minutes! It is so light, creamy, and delicious!


  • 1 small box instant chocolate pudding (3.9 oz)- I like to sift the pudding mix
  • 2 c. heavy cream or whipping cream


Combine the sifted pudding mix and heavy cream in a mixing bowl. I prefer to mix with a hand held mixer, but a whisk is fine too. If using a mixer, start on low speed until well combined.

Then, switch to high speed and whip the pudding until thick and fluffy. If mousse is too thick, mix in a bit more heavy cream until you reach the desired consistency.

If mixing by hand, simply whisk rapidly for a couple of minutes or until mixture is nice and thick. Refrigerate until ready to use.


*Sifting the pudding mix is an optional step but I do find that instant pudding mixes often have a few tiny hardened granules that either do not dissolve or take longer to soften. You will see what I mean when you sift ;0) . I do this for cake mixes also!

  1. Bebe I use Godiva instant pudding mix. I’ll try to use Jello-o next time. I mixed it for a while but it wasn’t whipped all the way yet when I took the picture. It turns out thick and tasty , but those little clumps are the only issue I’m having.
    Thank you for your response!

  2. Hi Tatiana, Maybe if you sifted the Godiva pudding mix that would eliminate the little clumps that are not dissolving.

    1. Hi Amy, yes you can make this filling in advance- I'm sure a couple of days ahead would be fine. We've used this as a filling in many cakes and have never had an issue with deflating, etc.

      As a general rule, it's a good idea to remove cakes from the refrigerator a couple of hours before serving so that the cake has a chance to warm up and soften a bit.

  3. Hi, my name is Laura. I am making 72 cupcakes for Mr great grandson's baby shower. I am going to use the chocolate, cheesecake and lemon pudding...do I have to refrigerate all of them if I fill the cupcakes 4 hours before the baby shower? Thank you.

    1. Hi Laura, With this perishable filling, I think having the cupcakes sitting out 4 hours before serving will be too long. I think the refrigerated cupcakes could come out of the refrigerator 1 1/2 hours to 2 hours before serving . This will give the cupcakes time to gradually lose their chill giving a better taste when eating. Hope all goes well.
