Step 1

For the cakes, preheat the oven to 180C/350F/Gas Sit 12 paper cases in a muffin tray.

Step 2

Beat the butter and sugar in a bowl until pale and creamy. Add the eggs, one at a time, and beat until well combined.

Step 3

Fold the flour, raspberries and passion fruit pulp into the mixture until almost smooth. If the mixture looks too stiff, add a little milk, as necessary.

Step 4

Divide the mixture among the paper cases then bake for 20 minutes. Remove from the oven and set aside to cool in the tin for 10 minutes. Turn the cakes out onto a wire rack and set aside until completely cooled.

Step 5

For the icing, using an electric whisk, cream the icing sugar and butter together until light and fluffy. Whisk in the vanilla pod seeds and food colouring. Gradually whisk in enough milk to form a smooth paste.

Step 6

Spoon the icing into a piping bag with a large star-shaped nozzle and pipe the icing over the cake. Sprinkle over the hundreds and thousands.
