Apple and Marzipan Rolls

2 ½ cups (350g) all purpose flour
7g dried yeast
¼ cup (50g) granulated sugar
1 large egg
100g unsalted butter, melted
1/3 cup (80ml) whole milk, lukewarm
½ teaspoon vanilla extract
200g golden marzipan, grated – I used homemade, recipe here
1 large Granny Smith apple
½ cup (75g) golden raisins
½ teaspoon ground cinnamon
icing sugar, for dusting

Place the flour, yeast and sugar in the large bowl of an electric mixer fitted with the dough hook. Make a well in the center and add the egg, butter, milk and vanilla and mix to combine. Mix at low-medium speed until it starts to form a soft dough. Continue mixing for 5-6 minutes or until dough is smooth and elastic – or knead by hand for about 10 minutes. Transfer to a lightly buttered large bowl, cover with plastic wrap and leave in a warm place for about 1½ hours or until the dough has doubled in size. Meanwhile, butter a 23cm (9in) round cake pan.
Punch the dough with your fist to deflate, then tip it out onto a floured surface. Roll the dough out to a 40x20cm (16x8in) rectangle. Scatter the marzipan over the dough to within 1cm (½in) of the edges. Peel, core and chop the apple and scatter over the marzipan. Mix the raisins with the cinnamon and sprinkle them over the apples. Starting from a long edge, roll up the dough into a long, thin sausage shape.
Using a small sharp knife, cut the dough into 8 even-sized pieces. Place them with their cut sides face-up in the prepared tin. Cover loosely with a piece of buttered plastic wrap and leave to rise again (prove) for about 1 hour until the buns have risen and become tightly packed in the tin (mine took 2 hours to prove). Towards the end of the proving time, preheat the oven to 190°C/375°F.
Uncover the buns and bake for about 30 minutes until deep golden. Cover with foil towards the end of the cooking time if they start to over-brown. Cool in the pan over a wire rack for 15 minutes then carefully unmold onto the rack. Dust with icing sugar and serve warm or at room temperature.
