Drizzled with an oozing chocolate ganache, these cupcakes are wickedly rich (but light in texture) and have a surprise of intense raspberry tartness hidden right in the middle!
Don't worry, you haven't done anything wrong – these cupcakes are meant to have a hole in the centre... Because the mixture is flourless, the raspberry jam sinks during baking creating a crater of sorts, giving them their name. 

Ingredients

180g good-quality dark chocolate (45% or 70% cocoa), chopped (see Baker's Tips)
125g butter, cubed
60ml (1/4 cup) water
220g (1 cup) brown sugar, plus 2 tablespoons extra
85g (3/4 cup) hazelnut meal
25g (1/4 cup) desiccated coconut
3 eggs, at room temperature, separated
85g (1/4 cup) raspberry jam

Chocolate ganache
180g good-quality dark chocolate (45% cocoa), finely chopped
60ml (1/4 cup) pure (pouring) cream

Method

1. Preheat the oven to 180°C (160°C fan-forced). Line a 12-hole 80ml (⅓ cup) muffin tin with paper cases.
2. Combine the chocolate, butter and water in a medium saucepan and stir over a low heat until melted and smooth. Remove from heat, add the sugar, hazelnut meal, coconut and egg yolks and stir well with a wooden spoon until well combined and any lumps have broken up. Transfer the mixture to a large bowl.
3. Place the egg whites in a clean, dry medium bowl and use electric beaters with a whisk attachment to whisk until soft peaks form. Add the extra 2 tablespoons of brown sugar and whisk until thick and glossy. Add a large spoonful of egg white mixture to the chocolate mixture and use a large metal spoon or spatula to fold in – this will ‘loosen’ the mixture. Add the remaining egg white mixture and fold in until just combined.
4. Divide the mixture among the prepared muffin holes. Place a teaspoon of raspberry jam in the centre of each cupcake and press down gently until the jam is in line with the top the cupcake mixture. Bake in preheated oven for 30-35 minutes or until the top of the cupcakes feels set and crumbs cling to a skewer inserted into the side of a cupcake. Remove the cupcakes from the oven, and stand in the tray for at least 5 minutes before transferring to place a wire rack and cool completely.
5. To make the Chocolate Ganache, place the chocolate in a heatproof bowl. Place the cream in a small saucepan and heat over medium heat, stirring occasionally, until the cream almost comes to a simmer. Pour the hot cream over the chocolate and set aside to stand for 3 minutes. Stir the chocolate and cream mixture until the chocolate melts and the mixture is smooth. Set aside, stirring occaiosnally until thickened to a thick pouring consistency (see Baker's Tips).
6. Drizzle a generous spoonful of ganache on the tops of the cupcakes around the hole in the centre, allowing it to dribble over the sides and down into the hole. Set aside for about 30 minutes or until the ganache sets before serving.
