How to make the dreamiest chocolate cake filling

A slice of classic, moist and tender chocolate cake will solve many problems. Not all problems, but we believe there’s a lot that a good cake can do. Agree? Whether you’re baking for fun, for a special occasion, or for a short home-ec baking activity, our easy chocolate cake filling is tasty, light and creamy, and simple enough for anyone to make! So if you have little ones at home, don’t hesitate to have them join in!

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!

  1. Place the cream cheese in the bowl of a stand mixer (or bowl with a handheld mixer). Beat the cream cheese until smooth- you’re going for no lumps.
  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.

This recipe makes about 3-1/2 cups of cake filling. You can store any leftovers in the refrigerator for up to two weeks.

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

    1. Dahn Boquist says:

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

  2. Sara Jack says:

    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!!!

    1. Dahn Boquist says:

      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.

  3. Tootilou says:

    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.

    1. Dahn Boquist says:

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

  4. Kristy ODonnell says:

    Will this recipe hold well out of the fridge for a few hours?

    1. Dahn Boquist says:

      Yes, it will. FDA guidelines recommend 2 hours outside of the fridge but I’m a bit of a rebel and I will leave it out all day as long as it isn’t in the sun.

  5. Holly Michelli says:

    Can I fill cupcakes with this the day before and keep them successfully in the refrigerator?

    1. Dahn Boquist says:

      Yes, you can. This filling holds up very well

  6. STACEY MILLER says:

    Does it squish out the sides when in a layer cake? Do I need to pipe a buttercream dam to keep it in or is it stiff enough to work on its own?

    1. Dahn Boquist says:

      No this filling is quite firm and holds up on its own. It will hold a heavy butter cake and you don’t need to make a dam with buttercream. This is a filling that makes cake decorating quite easy. Thanks for your question

  7. Roni Lett says:

    Can I use half and half instead of whipping cream

    1. Dahn Boquist says:

      It won’t get as thick if you use half and half

  8. Theresa Deatherage says:

    I made this for my Chocolate loving 10-year old’s birthday cake. Everyone loved it!

    1. Dahn Boquist says:

      Oh wow! Double digits this year. Happy birthday to the kiddo 🙂 Thanks for the comment

  9. Diane Zeigler says:

    Do I need to refrigerate my cake with this filling in it?

    1. Dahn Boquist says:

      Yes, if you will not be serving it on the same day then you should refrigerate it. The cake and the filling will taste better if you let it come to room temperature before serving it.

  10. angiesrecipes says:

    Looks absolutely delicious with just a few simple ingredients..and it reminds me of unbaked chocolate cheesecake.

    1. Dahn Boquist says:

      Thanks Angie, it is a bit like cheesecake but a bit more spreadable 🙂
