Chocolate Lime Cake

A retro chocolate and lime combination, this cake is a good one. A chocolate sponge flavoured with lime zest is drizzled with lime syrup as soon as it comes out of the oven. Chocolate shavings over the top are optional, but recommended.

  • 100 g light muscovado sugar
  • 100 g unsalted butter - softened
  • 1 lime - organic or unwaxed
  • 2 medium eggs
  • 125 g wholemeal spelt flour
  • 1 scant tsp baking powder
  • 1 rounded tbsp cocoa powder
  • pinch sea salt
  • 50 ml buttermilk, kefir or sour milk
  • 25 g golden caster sugar
  • 15 g chocolate shavings (optional) I used sea-salted chocolate


  • In a large bowl, cream the sugar and butter until light and fluffy.
  • Beat in the grated lime zest, followed by the eggs.
  • Sift in the dry ingredients, discarding any bran left in the seive. Stir until just incorporated, then stir in the buttermilk or kefir.
  • Spoon mixture into a 15 cm (6") round greased and/or lined cake tin. Level the top.
  • Bake in a pre-heated oven at 180℃ (350℉, Gas 4) for 35 mins or until the cake is risen and an inserted skewer comes out clean. Alternativley bake at 160℃ in an Optimum HealthyFry for 30 minutes.


  • Whilst the cake is baking, gently heat the sugar and lime juice in a small pan until the sugar has dissolved. Simmer for a couple of minutes.
  • As soon as the cake is removed from the oven, make small holes all over with a toothpick and pour the warm syrup over the top.
  • Leave to cool in the tin for 10 minutes, then turn out onto a wire rack to cool completely. If liked, decorate with chocolate shavings when ready to serve.


This makes a modest cake for 4-6 people. Double the quantities for a 20cm (8") round cake.
