Lemon and Thyme Cake

There is something about baking with fruit and herbs together. The sweet, sharpness from the lemon combined with the woody herb flavours, makes an amazing flavour combination. Top with the vanilla frosting and you have a light and airy, flavour filled cake.

I know some people find the idea of baking with herbs a little strange,  but trust me on this one, it is delicious! I added buttermilk into this recipe also, so it tastes even creamier than a normal sponge cake.

  • Divide the mix between the two tins
  • Bake for 30-32 minutes, or until a skewer inserted into the middle comes out clean.
  • Leave to cool in the tin and then transfer to a wire cooling rack.
  • To make the buttercream, cream together the butter and icing sugar, add in the water and vanilla during mixing. Use a handheld or an electric mixer for ease. Beat together until smooth and creamy.
  • Now to ice the cake; place one of the sponges onto the plate or cake stand, spread half of the icing over the sponge. Place the second sponge on top and top with the remaining icing.
  • Decorate with lemon slices and sprigs of thyme.
  • Enjoy!
