This recipe only requires 5 ingredients and 5 minutes to whip together! Here’s what you’ll need:

  • cream cheese
  • powdered sugar
  • unsweetened cocoa powder
  • heavy cream
  • instant chocolate pudding mix

To make this, you’ll need a standup mixer or a hand mixer since the cream cheese needs to be beat until smooth and it requires a lot of whipping to get the mousse-like texture.

Here’s the quick rundown of how it’s done, but be sure to check out the full recipe at the bottom of the page!

  2. Add the powdered sugar and cocoa powder, stirring on low until both ingredients are well combined.
  3. Turn the speed up to high, beat until smooth.
  4. Turn the speed to slow, then add the whipping cream and whip until the mixture is smooth.
  5. Add the powdered instant pudding mix, increase the speed, and whip until the chocolate cake filling is thick and fluffy.

Can you use this recipe with different flavored instant pudding?

Yes, but since this has some additional cocoa powder, our vanilla cake filling will make a better 'base' recipe to use with different flavors.

I had to add a little extra whipping cream to loosen it up a bit. My family are big fans. It’s light and creamy and delicious. The chocolate flzvor develops as it sits. A keeper

Can I freeze the leftover filling? I only needed half of it for now and didn’t think to cut the recipe in half.

Absolutely, this filling freezes very well. Thanks for the question

I just made this as a filling for my nephew's birthday cake. I doubled the recipe because i was doing a big layer cake. It came out very thin! Not mousse like texture at all! More like regular pudding consistency. I trued adding more powdered sugar and beat for longer, but no improvement. HELP! I have no filling now!!!

Make sure you are using instant pudding mix and not the kind that needs to be cooked. Also, you need to use cream for this recipe and not milk. You should be able to fix the filling if you get a package of powdered instant pudding and whip it into the mix that you already have.

Just made this yesterday for birthday party today. My batch came out very very thick so I globed it on thick and had plenty. If my cake hadn’t been frozen probably would have thinned it to spread more easily. The cake sat out on table the whole time. No problem. And everyone took seconds! Yummy! Will make again.

Thanks for the comment. If you make it again and it is still thicker than you like, you can add a tad more cream.
