  1. Cara says:

    My cream cheese and choc mix ended up runny and was not stiff like yours in video, hence when folding the cream in, it was not pipeable and too soft to fill a cake. Wondering if the qty’s are correct?

    1. Dahn Boquist says:

      Make sure you use block cream cheese and not spreadable cream cheese that comes in a tub. You also need to make sure the white chocolate mixture cools to room temperature. If the mixture is even slightly warm, it will melt the cream cheese and end up runny. If the mixture turns out runny, don’t add the whipped cream to it. You can chill the mixture in the fridge until it gets firm then whip it and fold in the whipped cream.

    2. Cara says:

      @Dahn Boquist, thank you. I think my white choc mix must have been too warm then. Yes it was definitely block cream cheese. To save it, can I add more cream cheese and cream to thicken a bit?

      1. Dahn Boquist says:

        You should be able to save it by folding more whipped cream into the mixture. Since that will ‘dilute’ the sweetness from the white chocolate, I would recommend adding a couple of tablespoons of powdered sugar when you whip the cream. If the cream cheese mixture gets a bit too firm after it sits in the fridge, beat it with an electric mixer to soften it up enough so you can fold the whipped cream in easily.

  2. Lynn says:

    Can you use white almond bark for the white chocolate

    1. Dahn Boquist says:

      I am sure that will work just fine. I haven’t tried it with this recipe, however, as a general rule, almond bark almost always works well as a 1:1 substitute for white chocolate. If you try it, I would love to hear how it goes.

  3. Marie says:

    Will this filling hold up okay in a cake made one day in advance and left in the fridge overnight?

    1. Dahn Boquist says:

      Yes, it will. You can decorate a cake with this filling up to 3 days in advance if needed. The white chocolate really helps keep it stable.

    2. Marie says:

      @Dahn Boquist, excellent thank you so much.
      I am filling a red velvet cake with this I’m excited to try it.

  4. Kassie says:

    What happens if I use store bought whipped cream?

    1. Dahn Boquist says:

      If you are talking about the cans of whipped cream, that won’t work well. A lot of those cans have water and other ingredients included and the whipped cream that comes out of it will not hold up in this. You may be able to fold the cream cheese (after you whip the cream cheese) into some Cool Whip, but I have not tried that so I don’t know how it will work. Any pre-whipped cream from the store will also add additional sugar and it will probably be too sweet after you add the white chocolate.

  5. Sharon says:

    Can I add fresh raspberries or sliced strawberries to this and use that as cake filling, or will it get runny?

    1. Dahn Boquist says:

      Yes, you can add fresh fruit to the mousse but it will not last as long. Sliced fruit will seep liquid quicker than whole fruit. When I add whole fruit, I find the mousse will last for as long as two days but sliced fruit usually starts to seep after 24 hours. It varies depending on the ripeness of the fruit. Your safest bet is to add the fruit between 4 and 12 hours before serving.

  6. Beverly Mae Nisbeth says:

    Can I omit the cream cheese and still use as a cake filling?

    Beverly

    1. Dahn Boquist says:

      You can but it will make a sturdier cake filling if you use cream cheese. If you don’t want to use cream cheese, mascarpone works well as a substitute

  7. shirley says:

    what happens if I don’t see stiff peaks after 5minutes?

    1. Dahn Boquist says:

      If you are not able to make the cream whip to stiff peaks it is probably because the cream is not cold enough. Make sure the cream is cold and it also helps to have a cold bowl.

  8. Taylor says:

    How long does this last in the fridge?

    1. Dahn Boquist says:

      It will last for 3 to 4 days in the fridge

  9. Tiffany says:

    How long does this keep at room temp, in a cake covered with ganache?

    1. Dahn Boquist says:

      You can safely keep it at room temperature for two hours. I will admit that I have kept it at room temperature for much longer than that (up to five hours) without noticing any change in the structure, texture, or flavor of the mousse. The best practice for safety standards, however, is two hours.
