Bake this rich date and walnut loaf at the weekend to enjoy during the week. You can freeze it for another day to serve to last-minute guests, too
Whisk in the sugar until smooth, then gradually whisk in the eggs until combined. Beat in the baking powder, flour and a pinch of sea salt until there are no lumps of flour left and it’s smooth. Fold in three-quarters of the walnuts, then pour into the prepared tin. Sprinkle the remaining walnuts over the top.
Bake for 20 mins, then turn the oven down to 170C/150C fan/gas 3 and cook for another 45-50 mins until golden brown and a skewer inserted into the centre comes out clean. Leave the cake to cool in the tin for 15 mins, then transfer to a cooling rack to cool completely. Lightly dust with the icing sugar and serve in slices. Freeze whole or cut into slices, then place in an airtight container or divide between reusable freezer bags. Can be frozen for up to three months. Defrost thoroughly overnight.
