White chocolate buttercream, easy to make and perfect for piping onto cupcakes, layer cakes, macarons or special celebration cakes.My buttercream recipes seem to be very popular on here. I’ve had a few requests for a white chocolate version so not wanting to leave you without the recipes you need, here it is! If there’s a flavour of cake or buttercream that’s not on here but you’d like to see, then let me know and I’ll do my best to add it.

This white chocolate buttercream is based on my yummy milk chocolate buttercream, where equal quantities of butter and icing sugar are beaten together and then lots of melted white chocolate is added. It gives you beautiful smooth buttercream that is the perfect consistency for piping.

White chocolate buttercream, easy to make and perfect for piping onto cupcakes, layer cakes, macarons or special celebration cakes.Here’s a few tips for getting it just right…

  • Melt your chocolate over a bain marie (in a bowl over a pan of simmering water). When I use milk or dark chocolate I’m happy to melt my chocolate in a pan on the hob, but I find that white chocolate is a bit temperamental and can easily go a bit grainy. The heat over a bain marie is gentler. You could also use the microwave using short bursts (20 seconds at first and then 10 seconds, stirring in between each one).
  • Use chocolate from the baking aisle in the supermarket (it’s less temperamental than the chocolate from the sweet aisle).
  • Make sure you let your chocolate cool to room temperature before adding it to the butter and sugar, otherwise it’ll melt the butter and you’ll end up with runny buttercream.
  • You should find that your buttercream is the perfect consistency for piping. If it’s a little stiff then beat in a little milk (no more than 1 tsp at a time). If it’s a little too soft then pop it into the fridge for a few minutes to firm up slightly.

  1. How long would this buttercream last in fridge to stay fresh?

  2. Does the chocolate in the butter icing make it more stable on a hot summer day? Was thinking of this for a nude wedding cake I’m doing for September and then adding things like raspberry jam, lemon curd etc. for different cake flavours but I’d be making it one or rwo days before if pissible!

  3. Hello Charlotte,
    I used this recipe with your chocolate cupcakes recipe and they tasted amazing. I love white chocolate but you don’t often find cakes with white chocolate frosting. I fancy having a go at your chocolate orange cupcakes next, just need to find a good excuse.
    Thanks
    Wendy

  4. Holy Sh*t. This is the best butter cream I have ever made/tasted. There’s no looking back. This will now be my staple go to buttercream Base. P.S. I did use the wilton white-white icing colour in it and it’s come up a lovely off white ivory colour. I guess you could add more but I stopped where I was happy. Just about to make a second batch. Maybe to ice the cupcakes… Maybe to just eat. I’ll see how I feel when the time comes. Lol

  5. Hi Charlotte, I’ve just found your website and I have two questions about this recipe, I hope you don’t mind. I’m looking for frosting / decoration options for my wedding cake (and I’ve never made a cake before where the decoration mattered!). It will be a small chocolate cake for a small ceremony (picture the top tier from a big wedding cake on its own). Would this frosting be this suitable to cover the entire cake with a cake turntable and then stick sugar paste roses on top? And is it possible to make this whiter by adding (and I apologise for even mentioning the word) superwhite or something similar? Thanks for the brill recipe x

    • I’ve not tried adding any sort of whitening to this to know if it could be brightened up, sorry. If you want your cake to look really white then would you consider a layer of buttercream and then fondant on top. That’s what I usually do when I make cakes as I’m not fussed on the flavour of fondant so I have a nice layer of buttercream for the flavour and then the fondant is really just for decoration. If you’re happy with the colour and just want buttercream then you can definitely use it as the main icing with fondant flowers on top. It’s best to apply the buttercream in a few layers to get it really smooth and avoid getting crumbs in the icing, letting each layer harden before adding more.

  6. Can I put the cake in the fridge once it’s iced or will the chocolate cause the buttercream to harden? I need to add raspberries to the icing so I’d like the cake to go in the fridge overnight.

    • If I have room I always like to store my cakes with buttercream icing in the fridge due to the butter in the but I’ve found that they’re fine stored outside as long as the room isn’t too warm. The icing will firm up more in the fridge but will still definitely be soft enough to eat, and it will soften a bit once it’s been removed from the fridge if it’s left to sit at room temperature for a little while.

  7. Hi i was looking at making a white chocolate cake for my sons 3rd birthday but the amounts of choc needed for the cake and buttercream was crazy! I was thinking id make a plain sponge with rasberry jam and then this white chocolate buttercream in the middle and then dyed green for the sides. Do you think it would go ok with plain sponge cake or would it be too sweet?

    • It should go well and will be lovely with the raspberry jam. Usually buttercream is made with twice as much sugar as butter but this is very sweet once the extra chocolate is added. My version has equal amounts of sugar and butter so is slightly less sweet.

  8. Hi Charlotte I’m debating whether to do your vanilla or choc sponge for my hubby’s bday next weekend. I’ve made the vanilla one a few times now so was thinking to make something different. But I’m planning to attempt making a bicycle out of fondant to go on the top (he’s a keen cyclist!) so don’t want to use choc buttercream as want a different colour to brown. (I’m a total beginner with cake decorating so don’t want to attempt fondant icing all over the cake!) Would I be able to add gel food colouring to this white choc buttercream or would I be better off using your vanilla one and colouring that like I’ve done in the past? I just thought that white choc might go better with the milk choc cake than vanilla. Thanks.

  9. Has anyone tried this as a filling for the chocolate Birthday cake, would it work?

    • I haven’t but I’ve tried it on the chocolate cupcakes and it would absolutely work.

    • It worked a treat, was delicious and actually prefare it to the chocolate butter cream. About to make again this week, Sons wife has requested it for his Birthday. Thanks for sharing.

  10. Can this be made the day before and pipped? The next day

    • Charlotte Oates

      I’ve not tried it but buttercream will form a bit of a crust once it’s been made so I don’t think it would pipe well the next day. If you stored it in the fridge in an airtight bag and then let it come up to room temperature before piping it may work.

  11. This looks yummmm!! I love white cream especially on chocolate cake 🙂 Thanks for sharing
