Drain and dry the raisins with a piece of kitchen paper

Place nine cupcake cases (I usef square shaped sillicone cases) on a baking tray

Melt the milk chocolate in your preferred way - I break it into a pyrex bowl and put in the microwave for a minute and a half on defrost.

Set the chocolate aside to cool slightly, while in a large bowl you whisk together the melted butter, syrup and egg yolk ( if using)

When combined, add the cocoa powder followed.by the melted milk chocolate.

Line a 9*9 inch square cake tin with baking paper and preheat oven to 350F/180C

To make the brownies, beat together the butter and sugar until light and fluffly.

Add the eggs little by little, mixing each bit in welll.

Sift in the flour, cocoa powder and baking powder.amd mix in with a metal spoon.

Pour mixture into the prepared tin and bake for 30 minutes at 350F/180C

Remove from the oven and allow to cool 10 minutes in the tin before removing cake to a cooling rack (run a knife along the sides if it needs help)

Allow cake to cool thoroughly.

To make frosting, melt the milk chocolate, allow it to cool slightly before mixing in the cream cheese until there are no lumps left.

Spread the frosting over the cake, then use a butter knife to demarcate nine small squares in the frosting. Place one nest on each square.

Refrigerate until ready to serve. Cut out individual square cakes for each person.
