  • 225g light muscovado sugar 
  • 75g chopped walnuts 
  • 150g grated carrots

  • A handful walnut halves, to decorate 

Method

  1. Preheat the oven to 180°C/Fan 160°C/Gas 4. Grease a 23cm (9 inch) deep square cake tin and line the base with baking parchment.
  2. Measure all the ingredients for the cake into a large bowl and beat well until thoroughly blended and smooth. Turn into the prepared tin and level the surface.
  3. Bake in the pre-heated oven for 1 hour until the cake is well risen and shrinking away from the sides of the tin. Leave to cool in the tin for a few minutes then turn out, peel off the parchment and finish cooling on a wire rack.
  4. For the topping, measure all the ingredients, except the walnuts, into a bowl or into a food processor, and blitz until smooth. Spread over the top of the cake with a spatula and decorate the top with the walnut halves. Chill a little before serving and store in the fridge as the topping is soft.
