Equipment

Ingredients
 

Lemon cake

  • 270 g (1 ¼ cups) unsalted butter
  • 280 g (1 ½ cups) white sugar caster
  • 2 lemons’ zest
  • 5 eggs
  • 1 ½ teaspoon vanilla extract
  • 5 tablespoon milk
  • 3 ½ teaspoon vegetable oil
  • 280 g (2 ¼ cups) all-purpose flour ** plain flour
  • 4 teaspoon baking powder

Lemon buttercream

  • 175 g (¾ cups) unsalted butter softened
  • 425 g (3 ½ cups) icing sugar
  • 1 ½ tablespoon lemon juice fresh, roughly 1 lemon’s juice
  • 1 tablespoon milk or heavy cream optional
  • Pinch of salt optional

Cake filling

  • 200 g (7 oz) lemon curd *** store-bought or homemade

Instructions
 

Lemon cake

  • Preheat oven: 180°C / 160°C (fan) / Gas Mark 4 / 350°F
  • For the sponges, 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, then beat in the milk, oil and vanilla extract until fully combined.
  • Sieve in the flour and baking powder, folding gently together until only just combined.
  • Divide the batter evenly between two greased and lined 8-inch cake tins and bake in the oven for 25-30mins until risen and skewer comes out clean from the middle of the cakes.
  • Allow the cakes to cool in the tins for 20mins then remove from the tins and transfer to a wire rack while you make the buttercream.

Lemon 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 lemon juice and salt (if using), mixing until only just smooth.
  • If needed, stir in milk or cream 1 teaspoon at a time until you get a thick but spreadable consistency.

Assembly

  • Once the cake sponges have cooled, place one onto a flat plate or cake board and pipe a circle of your buttercream around the edge in a ring to make a wall.
  • Spread roughly ½ jar of lemon curd inside the frosting ring, then place the second sponge on top.
  • Cover the cake (top and sides) in the rest of the frosting, smoothing lightly with a spatula.
  • Decorate your cake with buttercream swirls, slices of lemon and/or edible flowers, and enjoy!

Notes

* I like to use a piping bag to pipe a ring of frosting to hold the lemon cake filling inside. You can instead use a plastic freezer bag with the corner cut off.
** You can swap the plain flour for self-raising flour of the same quantity and reduce the baking powder in the recipe down to 1 tsp.
*** You can use a premade store-bought lemon curd (usually need ½ a standard jar) or make your own from scratch using this lemon curd recipe.
