200 grams egg whites - 5 egg whites
275 grams caster sugar
450 grams unsalted butter - cut into cubes
2 tsp clear vanilla extract
- Heat up the egg whites with the sugar until it reaches 80 C.
- Whisk the meringue at high speed for some 8 minutes or so until the bowl is not longer hot but just slightly warm.
- Then add the vanilla extract to the meringue and continue whisking at high speed.
- Then add the butter cubes a little at a time until all the butter has been added and continue to whisk at high speed to make sure the butter cream does not curdle.
- There is enough butter cream to pipe about 30 standard American cupcakes - that is those with 2 inch bottom.
- Any leftover butter cream can be stored in an airtight container and refrigerate for a week or frozen for a month. When you want to use the butter cream again, bring it to room temperature and beat the butter cream using a pedal attachment, like a K beater or a creaming beater, until the right consistency is achieved.
- If you want to use any colouring with the butter cream, you need to use paste or gel colouring and NOT liquid colouring
