100g of California walnut pieces
125g of butter, softened
125g of caster sugar
3 medium eggs
150g of self-raising flour
½ tsp of baking powder
Step 1Preheat the oven to 180°C, gas mark 4. Grease and base line a 1kg loaf tin.
Step 2Place 50g of walnuts in a food processor and blitz to a coarse powder, chop a further 25g.
Step 3Whisk the butter and sugar in a large bowl until pale and fluffy. Whisk in the zest of 2 lemons and then whisk in the eggs, one at a time. Fold in the flour, baking powder and prepared walnuts to give a smooth batter. Spoon into the prepared tin and bake for 35-40 minutes until golden and a skewer comes out clean.
Step 4Just before the cake comes out of the oven, mix the juice of 1 lemon with granulated sugar. Chop the remaining 25g of walnuts and stir into the syrup. Prick the cake with a skewer several times and drizzle over the lemon syrup. Allow to cool a little in the tin before removing, and then cool completely.
