There is a lot of ingredients in this- it's the perfect recipe, but a lot. You could work out how much you would need, but lots of people don't like maths.

Far too much butter/margarine. I could not get this to stiffen up no matter how much icing sugar I put in. I’ve ended up just spooning it over the cake in a bowl like custard! The ratios are wrong.

It's the correct quantities of each. But, unless you use butter (NOT margarine) it won't stiffen up.

Even for 25 cm cake the ratio to much. I did 300g icing sugar to 150 butter this was just right for what made. If I was putting it over and not sandwiched between it would be ok

Made an account just to review this recipe. Friends made it and it ended up looking a bit like baby sick. WHO PUTS BOILING WATER IN BUTTERCREAM YOU USE MILK IT'S NOT ROCKET SCIENCE. Water + fat = no

I lost my recipe for buttercream and couldn’t remember the ratios I used, so googled one and found this recipe, but I just used the ingredient ratios and not the method as I had my own. Be careful when adding the last 3rd of icing sugar, or the last bit, my buttercream was fine and then added the last 3rd of icing sugar and just turned into a crumbly, fondant like mess, tried adding more milk as that’s how I was always taught to make buttercream, and that didn’t help at all, I gave up at that point. I should’ve read the method to see about the boiling water but didn’t think I would’ve needed much liquid, probably use less icing sugar if you’re using this.

The recipe did not use enough liquid. I put in a few tablespoons of hot water and it worked out nicely

Thanks for your question. We'd suggest making 1.8kg buttercream.

I need to ice a 30 cm 3 layer cake, and also cover it completely with butter icing before covering it with ready to roll fondant icing. How much butter icing do I need to make ? Thank you.

Hi there, thanks for getting in touch. To be on the safe side, we'd recommend making three times the amount statedin the recipe, though you may not need to use it all. Hope it goes well! Thanks, BBC Good Food team
