  • 300 grams unsalted butter
  • 300 grams golden caster sugar
  • 4 large eggs
  • 300 grams Self Raising Flour
  • 1 teaspoon baking powder
  • 3 lemons
  • 3-4 tablespoons milk

Gin and tonic centres

  • 50 ml Whitley gin
  • 1 tablespoon lemon curd
  • 25 ml tonic water

Butter Cream

  • 300 grams unsalted butter
  • 700 grams icing sugar
  • 2 tablespoons milk
  • purple colour paste



  • Grease and line a 9 x 12 inch cake tin with grease proof paper.
  • Preheat the oven to 180ºC/160º fan.
  • Cream together the butter and sugar. You can do this entirely in a mixer or by hand.
  • Add the eggs one at a time.
  • Sieve in the flour and baking powder and mix together.
  • Zest the two lemons and mix it into the cake mix along with the juice from 1 lemon.
  • Spoon the cake into the tin and bake for about 45 minutes - 1 hour., until golden brown and when a cake tester comes out it's done. Leave to cool for 30mins and then remove from the tin and place on a wire wrack.

Gin and Lemon Centres

  • Add the gin, tonic and lemon curd into a saucepan and on a low heat mix together until it starts to thicken. Remove from the heat and set aside until ready (it should still be warm).
  • When the cake is cold divide up in to squares.
  • Using a metal nozzle of a knife carefully cut a 1 cm hold in the centre of each cake and move the hole piece and keep it to the side.
  • Spoon the gin and lemon curd mix into the holes almost up to the top and pop the cake top pieces back in.


  • In a stand mixer beat the butter gradually adding the icing sugar and the milk until light and fluffy and well incorporated.
  • If you want beautifully white buttercream add a tiny amount of purple food colouring paste. The purple will neutralise the yellow tint of the buttercream. Be careful to add a tiny amount at a time otherwise it will go purple.
  • Depending on how you want to decorate the finished cakes choose a different nozzle. I added dried lemon slices to the cakes so I used a large round nozzle to a pipping bag and fill it up with the buttercream.
  • Pipe a blob or beautiful swirl of buttercream on the cakes and decorate. I used fresh lemon slices but sprinkles work so well too!


If you want to use dried lemon slices as decoration cut thin slices of lemon and bake on a lined baking tray in a warm oven (about 160 degrees) for 3-4 hours. Flip them over every half an hour to make sure they dry out evenly.
