I must bake the cake in advance. Can I fill my layers with this filling, crumb coat it and then freeze it. Or can I do the frosting as well and what is the correct way to defrost is before use,.

Yes, you can assemble the cake in advance and freeze it. You can even frost it and decorate the cake prior to freezing, however it all depends on the type of frosting and cake you have as to how long it needs to defrost. The best way to defrost the cake is to place it in the fridge. It can take anywhere from 8 hours to defrost in the fridge to as long as a couple of days for a larger wedding cake. Typically, I will need about 8 hours for a standard, double layer cake to defrost in the fridge. The larger your cake and the more layers it has, the longer it will need to defrost.

Can I use this as a topping /icing ,as well? With chocolate spears to decorate or is it too soft?

Dahn Boquist

Sunday 1st of May 2022

Yes, you can use this to cover the cake. It isn't too soft for that. You may even want to add a couple of tablespoons of milk to make it more spreadable.

Can I add Peanut Butter to the Filling to make a chocolate/peanut butter filling?


Monday 18th of April 2022

@Dahn Boquist, just a thought but what if you used powered peanut butter?

Dahn Boquist

Monday 14th of February 2022

I have not tried it but I am sure it would work. I would suggest reducing the cream cheese to 4 or 6 ounces and adding 1/3 cup of peanut butter. If you add too much peanut butter it will probably get too soft. You might be able to add additional peanut butter after you mix everything but I would mix it up well with 1/3 cup then add a little more if it isn't too soft. I would love to hear how it goes if you try it.

Can you use this recipe with different flavored instant pudding?

Dahn Boquist

Thursday 28th of October 2021

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
