Tim's lemon trickle mash cake recipe

Hugh uses potato in his take on the classic lemon drizzle cake

Hugh: "The idea for this lovely, moist cake came from Elena Wong on our production team. It's best made with leftover whole potatoes, which you've mashed or, even better, riced once cold. If you're intending to make it with leftover mash, make sure it doesn't contain too much butter, milk, cream - or any flavourings such as mustard."

Serves 12


  • 175g unsalted butter, softened
  • 200g caster sugar
  • 4 eggs
  • 200g ground almonds
  • 2 tsp baking powder
  • 250g plain, cold mashed potato
  • Finely grated zest of 3 lemons

For the topping

  • Juice of 2 lemons
  • 75g caster sugar


How to make Tim's lemon trickle mash cake

1. Preheat the oven to 180°C/gas 4. Butter and line a 23cm diameter springform cake tin.

2. Beat the butter and sugar together until light, pale and fluffy (about 5 minutes in a mixer). Beat in the eggs, one at a time, adding a spoonful of ground almonds with each addition to stop the mixture curdling.

3. Stir the baking powder into the remaining almonds, then fold them into the mixture, followed by the mashed potato and the lemon zest. Spoon the mixture into the cake tin and bake for 30-40 minutes, or until a skewer inserted into the centre comes out with just a few moist crumbs clinging to it. Check it after 25 minutes to make sure it is not colouring too much, and cover with a sheet of foil if it is.

4. Leaving the hot cake in its tin, pierce it all over with a skewer, going quite deep, but not right through to the base. Combine the lemon juice and caster sugar for the topping and, before the sugar has had a chance to dissolve, pour the mixture slowly and carefully all over the cake. Leave to cool completely before serving.
