Active Time: 5 minutes
Total Time: 5 minutes
Servings: 12 servings


  • 250 g unsalted butter - soft at room temperature
  • 500 g icing sugar
  • tbsp Baileys Irish Cream - you can use any of their other flavours too


  • Cut the butter (250g) into cubes and then beat on a low speed until soft. Gradually add the icing sugar (500g - you add it gradually to stop it flying everywhere) and beat until fully combined.
  • Add the Baileys (2½ tbsp) a teaspoon at a time, beating in each addition before adding more.
  • Check the consistency of your buttercream. It should be soft and perfect for piping at this point. If it's a little too soft, pop it into the fridge to harden, checking it every few minutes.
  • Decorate your cakes.


Makes enough for 12 cupcakes or for covering and filling a 20cm 2-layer round cake.
Take a look at my mix-and-match cupcake creator to choose which cupcake sponge you want to pipe this onto and take a look at all my other buttercream flavours while you're there too.
