Try this simple, lesser-known buttercream made with condensed milk – it's great on coffee cake, but is a great frosting option for any kind of bake


Make this Russian buttercream, then try our Vietnamese coffee loaf cake, coffee cake recipe and Vietnamese coffee ice cream.

This is an incredibly simple buttercream with a wonderfully rich and smooth consistency. Unsalted butter is beaten until really pale, then condensed milk is slowly beaten in. As the milk is added, the texture becomes silky. The key to perfecting this is simple: make sure you beat the butter for at least 5 minutes before adding the condensed milk; it needs to be almost white. Any problems are easy to rescue. If, once you’ve added the condensed milk, the buttercream is split, that is a sign the butter was too warm. To rescue, put the bowl with the frosting into the fridge for 10 minutes and then rewhip until light and fluffy. If the butter is too cold to start with, you may find the buttercream is too dense. To correct this, take a third of the buttercream and microwave it for 10 seconds to warm slightly. Beat this back into the main bowl of buttercream.


  • 120g unsalted butter, at room temperature
  • 125g sweetened condensed milk
  • 1 tsp vanilla bean paste
  • ½ tsp fine sea salt


  • STEP 1

    Put the butter into a bowl and use an electric whisk to beat for 5 minutes, or until light and pale.

  • STEP 2

    With the motor running, slowly pour in the condensed milk, a little at a time, beating until the mixture is smooth and uniform before adding more.

  • STEP 3

    Beat in the vanilla and salt until you have a light, fluffy buttercream texture. It is now ready to use on your favourite bakes.
