Ingredients

Lemon cupcakes

  • 115 g unsalted butter
  • 115 g caster sugar
  • 1 lemon’s zest
  • 2 eggs
  • 115 g plain flour see notes for self-raising flour swap**
  • 1 ½ teaspoon baking powder
  • 2 tablespoon milk
  • 2 tablespoon lemon juice

Orange buttercream

  • 115 g unsalted butter
  • 270 g icing sugar
  • ½ teaspoon orange extract
  • 1-2 tablespoon orange juice or milk ***
  • teaspoon salt optional

Instructions

Lemon cupcakes

  • First preheat the oven to 180°C / 160°C (fan) / Gas Mark 4 / 350°F.
  • In a medium bowl, cream together the butter, sugar and lemon zest, either using a spatula, electric hand mixer or stand mixer, until light and pale.
  • Beat in the eggs one at a time until fully combined.
  • Sieve the flour and baking powder into the mixture, gently folding in until just combined.
  • Stir in the milk and lemon juice until smooth.
  • Line your cupcake pan with cases and divide the batter evenly between them (no more than ⅔ full).
  • Bake for 15-20mins until golden and springy, then transfer to a rack for cooling. Make the buttercream while the cupcakes cool.

Orange buttercream

  • Beat the butter (either by hand, using an electric mixer or stand mixer) until pale, light and fluffy. This could take several minutes.
  • Sieve half of the icing sugar into the butter and beat until combined, then repeat this with the remaining half of icing sugar.
  • Add in the orange extract, juice and salt (if using), mixing until only just smooth. You can also beat in a few drops of orange food coloring at this point is using.

Assembly

  • Once your cupcakes have fully cooled, add your buttercream to a piping bag fitted with a nozzle of your choice (e.g. large open star) and pipe large swirls onto each cupcake.
  • Decorate with a half slice of lemon and enjoy!

Notes

* If you don't have a piping bag and tips, you can instead use a plastic freezer bag with the corner cut off to pipe a ring of frosting onto your cupcakes.
** You can swap the plain flour for self-raising flour of the same amount and reduce the baking powder by 1 tsp.
*** You can use either orange juice (fresh or bottled) or milk to thin your frosting. Orange is more fruity flavour or milk will make it creamier!
