This vanilla cake filling is the easiest and fastest cake filling you will ever make. It tastes like a cross between vanilla mousse cake filling and a cheesecake filling.

The creamy filling is very similar in flavor to the filling in the middle of Costo cakes.

You know that creamy vanilla mousse texture that everyone scoops out of the center of the cake before they even eat the cake? This is it.

Similar to Costco cake filling:

That Costco cake filling is addictive and everyone that has ever had a Costco cake wants to know how they make the filling.

This recipe is going to satisfy your cravings and you’re going to be amazed at how easy it is to make.

So good!

Not entirely from scratch:

I almost thought about apologizing for this recipe. This vanilla cake filling is so far from my typical style of cooking that I won’t be surprised if I get a few snarky emails about how far I have fallen from the ‘from-scratch’ bandwagon.

It has happened in the past when we have used store-bought cookies for things like this Mocha chocolate icebox cake and this Girl Scout Samoas Chocolate Lasagna.

Then there is this meatloaf recipe that calls for a package of onion soup mix. We get emails from readers that get pretty upset when we use pre-packaged store-bought ingredients in our recipes.

But I just can not apologize for this recipe. It tastes great and holds up very well on a long, hot summer day.

If you can’t stand the idea of using a package of instant pudding in your cake filling then we have plenty of cakes with creamy, dreamy, luscious, fillings that are made entirely from scratch.

This coconut cake roll has a creamy filling with coconut essence. Then there is this lemon meringue cake that is filled with luscious lemon curd. So good! Or this Chocolate Guinness cake that I filled and frosted with Bailey’s cream cheese frosting.

You won’t be disappointed with our from-scratch recipes but this recipe serves some useful purposes.

Creamy and smooth!

A great filling for cake carving:

It is great for layering in a cake that you plan to carve.

Normally if you are going to carve a cake, a thick, stiff buttercream is the best thing to put between the layers. But I like putting yummy, creamy, luscious fillings between my cake layers.

The problem with putting creamy fillings between the layers of a cake you plan to carve is that it creates ‘slippage’.

When you start carving a cake, the layers have a tendency to slide if the filling is smooth and creamy.

This filling will hold the layers together as you carve the cake (as long as you don’t slather it on super thick).

I recently made a Barbie Cake where the cake was the gown for a Barbie doll. There were 8 layers of cake filled with this vanilla cake filling.

The filling did not slip and slide when I used a serrated knife to shape the cake layers to form the gown.

This filling holds cake layers together very well, so carve away.

Tastes like cheesecake mousse filling!

A great cake filling for hot weather.

This cake filling will hold up in long, hot, humid weather. That isn’t always a problem where I live in the Pacific Northwest. But we do have a few days of pretty intense heat in our summer months.

Nothing will destroy a cake more surreptitiously than a hot, humid day. One moment the cake looks perfect, then an hour later, you’re thinking “is that cake leaning?” And an hour after that, the cake is almost on the ground.

But not with this filling. This vanilla cake filling will keep your cake layers intact on those hot days.

And, if you are wondering.. does cream cheese frosting go with chocolate cake? Well, it does. It also goes with coconut cake, or whatever your heart desires.

Storing Cake Filling

You can make the filling ahead of time and store it in the fridge for up to 3 days. You can also freeze it for up to 6 months.

Just make sure you keep it in freezer proof containers if you plan to store it in the freezer.

Vanilla and chocolate go together perfectly. Fill this gluten-free chocolate cake with this vanilla mousse cake filling. 

Squirt some vanilla cake filling into the center of red velvet cupcakes before you add the frosting. It will be a delightful surprise.

    when I defrost the filling, do I need to return it to the mixer before use it?

    1. Dahn Boquist says:

      You shouldn’t need to unless it looks like it is separated or if you want to add a touch more cream to make it more spreadable. It usually defrosts just fine

    Hello,thanks for this recipe

    How do I substitute the dry pudding mix for a homemade Vanilla pudding that isn’t dry?

    I can’t seem to find the dry one here in Nigeria.

    Thank you

    1. Dahn Boquist says:

      Unfortunately, we don’t have a substitute for the instant dry pudding mix. The dry pudding mix has a modified cornstarch that thickens the filling without adding additional liquid.

  3. Angela says:

    Loved this!! Nice and easy. I was going a funfetti cake for my grand daughter and wanted a funfetti filling. Used this recipe added a little cake batter flavoring and sprinkles. Delicious!

    1. Dahn Boquist says:

      Great idea! Thanks for the comment, Angela.

  4. Danielle says:

    This filling was super easy to make and tastes delicious! I’ve made it twice now, the first time with a white chocolate pudding, the second with vanilla. Everyone ra:ed abiut the cake and of course the filling. There is plenty for a 3 layer cake (mine was a 9.something inch) and I have at least a cup left over. Approx how long will it keep in the fridge?
    Thank you for the recipe. Can’t wait for the family BBQ and my next cake. (Ps, I also squeezed into the center of raspberries and that was a hit).

    1. Dahn Boquist says:

      I’m so glad you enjoyed it. The filling will last for 3 days in the fridge and for 6 months in the freezer. It freezes very well. Thanks for the comment, the raspberries sound great, I’m glad that worked.

  5. Makayla says:

    Can’t even read the recipe. There is a giant ad blocking the ingredient list

    1. Dahn Boquist says:

      Can you send me a screenshot so I can help troubleshoot that issue?

    2. Melissa Garcia says:

      @Dahn Boquist, I’m running into the same issue on my phone and now on the computer too and was hoping to make it today for my daughters birthday cake.

  6. Suzanne says:

    This looks great and simple, I’ve never put filling in my cakes before besides buttercream so I’m excited to try it 🙂 Once assembled, does the cake have to stay in the fridge b/c of the cream cheese filling?

    1. Dahn Boquist says:

      If you don’t plan to eat the cake right away, you should keep it in the fridge. I like to let cakes sit at room temperature for two hours before serving it because the filling and buttercream will taste better at room temperature.

  7. Lee-Ann says:

    Hi just wondering if you could swap the vanilla pudding mix to a chocolate pudding mix to get a nice chocolate filling ??

  8. Sabina says:

    Can I substitute the heavy cream with half and half or whole milk?

    1. Dahn Boquist says:

      The filling will not get thick enough if you use half and half or whole milk.

  9. Taylor Hoover says:

    Would this be enough for a 12×18 sheet cake?

    1. Dahn Boquist says:

      Yes, this will fill a large sheet cake.

  10. Miriam says:

    This filling is fantastic!! If I wanted to use a ganache filling also, would spread this filling first and pipe a dam then add the ganache? Or spread ganache first, then this filling? Trying to avoid slippage and will use a dowel too.
    TIA!

    1. Dahn Boquist says:

      I would spread this filling down first then pipe some extra around the edges to make a bit of a dam for the ganache. A dowel sounds like a good idea. With the ganache and this filling on top of each other, it might get a bit slippery 😉

    2. Miriam says:

      @Dahn Boquist, perfect! Thank you Dahn!
