My chocolate cake and chocolate cupcake recipes are both not very sweet and have a dark rich brown colour, this buttercream is perfect for my recipes because this tends to be a bit on the sweet side which means it blends perfectly well with my recipes.

The downside of this recipe is its highly technical and requires a thermometer. But don’t worry I got you covered because this step by step recipe is going to make your life easy. But if you don’t have a thermometer or would like to attempt something simpler, then try my American buttercream recipe, which is equally delicious.

Difference between American buttercream, Italian meringue buttercream & Swiss Meringue Buttercream?

They all taste good, the only difference between meringue buttercream and just buttercream is meringue buttercream holds its shape better than normal buttercream which means it looks much better pipped.

American buttercream is made using icing sugar and cocoa powder.
Swiss meringue buttercream is made using egg white and sugar pasteurised up to 150F
Italian meringue buttercream is made using sugar cooked up to 150F then poured into the egg whites

Which is better, American buttercream or Swiss Meringue Buttercream?

Well, it actually depends on the use. if you want to pipe flowers and have a good piping definition or to have smooth edges when icing a cake, then definitely the swiss meringue buttercream is better.
but if you want an easy buttercream something to just frost a cake and add between layers for examples after frosting the cake you would want to pour a ganache on the top or add a sheet of fondant or marzipan to cover the cake, then an American buttercream is the way to go.
Italian buttercream is not used very often, I use this particular technique mostly to make meringues.

Why use chocolate Swiss meringue buttercream?

Easy to store for later– this can be kept in the fridge for upto 5 days or frozen for 2 months in an airtight container

Perfect for piping – it is a sturdy buttercream, therefore, it is so beautiful when piped

Not too sweet– unlike the american buttercream this is actually less sweet as there is egg white as a base
