Grind 75 g (3 oz) hazelnuts in a food processor. Roughly chop the remainder.
Lift the bread pan out of the machine and fit the blade. Put the ingredients, except the 4 tablespoons marmalade, in the pan, following the order specified in the manual.
Fit the pan into the machine and close the lid. Set to the cake programme. After about 5 minutes use a plastic spatula to scrape the mixture down from the sides and from the corners of the pan.
Test the cake after 1¼ hours by inserting a skewer into the centre. If it comes out clean the cake is ready. If not, cook a little longer or complete the programme.
Transfer the cake to a wire rack. Melt the extra 4 tablespoons marmalade in a small saucepan with 1 tablespoon water. (Sieve the marmalade to remove the shreds first, if liked.) Brush over the cake and leave to cool.
