In a small pan combine 70ml of milk, butter and half the caster sugar and stir well on a medium heat. Once your butter has melted, add your yeast.

In a bowl add your flour and lemon zest before adding in your warm milk mixture. In a separate bowl whisk your egg and 1/2 of the vanilla extract . Once mixed combine them both together to make your dough. Cover and place somewhere warm for at least an hour until the dough rises.

Preheat your oven to 200. Once risen, roll out the dough into a rectangle shape on a lightly floured surface. Spread your butter evenly over the dough before sprinkling on the remaining caster sugar and cinnamon.

Roll into a large sausage shape before cutting into 16 equal pieces. Place the rolls in to a Christmas tree shape on a tray lined with baking paper. Bake for approx 20 minutes.

Allow to cool slightly as you make your glaze drizzle. In a small bowl combine your milk, icing sugar and vanilla extract until smooth. Drizzle across your Christmas tree and serve.
