Gradually fold milk and sifted self-rising flour into the creamed mixture in two portions, mixing just until incorporated.

Transfer the batter to the prepared pan, smoothing the top evenly. Bake for 25 minutes, or until golden and a skewer inserted in the center comes out clean. Allow cake to cool in the pan for 5 minutes, then transfer to a wire rack and cool completely.

Cut the cooled cake into 24 even squares. Dip each square into the semi-set raspberry jelly, then immediately roll in a combined mixture of shredded and desiccated coconut. Place on a rack to set.

Using a serrated knife, slice each cake square in half horizontally. Spread raspberry jam on one side and pipe or spread vanilla cream on the other half. Sandwich together to finish.
