Raspberry & coconut slice (vintage edition)

Beat butter, sugar, and egg in a small bowl with an electric mixer until combined and stir in sifted flours. Spread the mixture over the base of a greased 19x29cm rectangular slice pan, and bake in a moderate oven for 10 minutes.

To make the topping, combine all ingredients in a medium bowl and mix well.

Spread the hot base with jam, then topping. Bake in a moderate oven for a further 30 minutes or until browned. Cool in pan.
