Preheat oven to 200°C/375°F and line a baking sheet with baking paper.

In a large bowl mix all dry ingredients. With your fingers rub in the butter cubes until crumbly. Add orange peel and soy yoghurt and knead until just combined. 

Roll out the dough on a slightly floured surface. The dough should be a little thicker than your finger. Cut out 8 round shapes, using either a glas or pastry ring. Place onto the baking sheet.

Bake on the middle rack for about 10 minutes. Take out and drizzle with glaze. Enjoy while still warm.
