Black and white pinwheel cookies
Black and white biscuits are a classic among Christmas cookies. You can make them into a checkerboard pattern or as a beautiful spiral like these
- Serves: 36 persons
- 300g plain flour
- 100g icing sugar
- 8g vanilla sugar or 8g caster sugar, plus 1 tsp vanilla extract
- 1egg, plus 1 egg white for glazing
- 125g butter, softened
- 1tbsp cocoa
- 1tbsp milk
Step 1Put the flour, icing sugar, vanilla sugar, a pinch of salt, egg and soft butter in a stand mixer and mix. Tip the dough onto a lightly floured worksurface and knead briefly by hand. Cut the dough in half. Wrap one half and chill for an hour. Knead the cocoa and milk into the other half. Wrap and chill for an hour.
Step 2Roll each batch of dough into a rectangle (about 30cm x 20cm) on a lightly floured worksurface. Coat the top of one layer with egg white then lift the other colour of dough on top and coat the top with egg white. Roll up tightly like a Swiss roll. Wrap and chill for 30 minutes.
Step 3Heat the oven to 175C/fan 155C/gas 3½. Line 2 baking sheets with baking parchment. Cut the dough into slices about 5mm thick with a sharp knife. Bake in batches for 10-12 minutes, but don’t let the pale dough darken as you want to keep the contrast. Allow to cool completely.
