Ingredients

  • 250 g softened butter
  • 500 g icing sugar
  • ¼ tsp vanilla extract
  • 3 tbsp instant coffee granules
  • tbsp boiling water

Instructions

  • Mix the instant coffee granules (3 tbsp) with the boiling water (1½ tbsp) and then set aside to cool.
  • Cut the butter (250g) into cubes and then beat on a low-medium speed until soft. Gradually add the icing sugar (you add it gradually to stop it flying everywhere) and beat until fully combined.
  • Add the vanilla extract (¼tsp) and add the coffee 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 still a little stiff then beat in a little milk.
  • Decorate your cakes (or just eat if off the spoon because it’s yummy!).

Notes

Take a look at my cupcake index for a selection of cakes to spread this buttercream on to. It goes particularly well with the coffee, vanilla and caramel cakes drizzled with a little caramel sauce.
