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.
- 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.

Charlotte Oates says
9 May 2019 at 2:55 pmIt’s absolutely fine unless the room is particularly warm. On a normal British day it’ll be fine for a few days.

Can i use vegan white chocolate? How long will the buttercream store for in the fridge? I am hoping to make buttercream day before asembling the cake.
Thanks

18 April 2019 at 12:20 pmI’ve never used vegan white chocolate so I’m not sure if it would work.
The buttercream will last for several days after making. However, you’re best spreading it onto the cake straight after making it as it goes a little fudgey in the fridge and will be harder to spread/pipe smoothly after chilling.

15 April 2019 at 11:38 amCould I make a large batch and then freeze it ready for when I need it?
Charlotte Oates says
18 April 2019 at 12:23 pmIt does freeze. However, the text goes a little fudgey so it won’t spread/pipe as smoothly afterwards.

13 April 2019 at 2:38 pmWould I need double recipe to only cover and decorate a 4 tier unicorn cake?
Thanks ☺️☺️
Charlotte Oates says
15 April 2019 at 8:16 amIt depends on a few things…
1) What size cake are you making?
2) How thick do you want the buttercream around the outside of the cake?
3) Are you planning on adding buttercream swirls? (most unicorn cakes I’ve seen have them)
