RECIPE NOTES & TIPS
Butter temperature - you want the butter to be room temperature but not soft. The best way to tell this is to gently press a finger on the packet of butter. It should give slightly. If the butter squishes then it is too warm.
Add the milk a little at a time - beating until you get the correct consistency. You don't want to add too much at once as this can make your buttercream runny!
Make sure you sift the icing sugar and cocoa powder - this will create a smooth buttercream without lumps!
Making fluffy chocolate buttercream - beat the butter until it’s completely pale, soft and creamy – this will take approximately 5 minutes. Stop every minute or so to scrape down the sides of the bowl.
Storage - store in an airtight container at room temperature for up to 4 days.
