Prep time: 10 min
Total time: 10 min
Yield: 12 servings
Ingredients: 250 g unsalted butter (soft at room temperature); 250 g icing sugar; 200 g white chocolate; A little milk (to get the buttercream to the right consistency, this may not be needed)

White chocolate buttercream, easy to make and perfect for piping onto cupcakes, layer cakes, macarons or special celebration cakes.

Skip to the recipe

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.

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.

I’m wanting to make a buttercream ruffle cake, would this recipe work for the ruffles?

  It may be tricky as this buttercream doesn’t crust like a more traditional vanilla buttercream. It should be fine if its a coolish day when you make it, but you make find it trickier on a warmer day.

Hey Charlotte
We share the same surname, so here’s to that I guess!
Would you suggest using this recipe in the summer? I will be baking a 2 layer cake with the burtercream as the middle and outside, and additional swirls on top.
I’m worried with the 50/50 butter content it won’t hold its shape in the heat/ humidity.
What do you suggest? Addition of corn starch? Does the chocolate add any stability?

  It depends where in the world you are. It’ll be fine on a traditional British summer day (unless it’s those two random days we always seem to get each year where it’s stupidly hot), the buttercream is pretty stable and will hold its shape. I wouldn’t leave the cakes sitting out in bright sunlight though as that could make the buttercream go funny (any type of buttercream, not just this one). I would recommend storing the cake in the fridge in summer to ensure it stays fresh, but allow it to come up to room temperature before serving as it’ll taste better that way.

Hi, just wondered what type of piping nozzle you used? is it a open/closed star nozzle? if so what size? i have a set but I’m not sure which to use.
PS I’m a novice at piping, so wondered which is the easiest to pipe with?
thanks in advance

Is the buttercream shelf stable at room temp?

  It’s absolutely fine unless the room is particularly warm. On a normal British day it’ll be fine for a few days.

Hi
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

  I’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.

Could I make a large batch and then freeze it ready for when I need it?

  It does freeze. However, the text goes a little fudgey so it won’t spread/pipe as smoothly afterwards.

Would I need double recipe to only cover and decorate a 4 tier unicorn cake?
Thanks ☺️☺️

  It 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)
