1. preheat the oven to 160°c, and line a 20cm square baking tin. transfer sweet potato to a food processor and blitz to a puree.
2. put the chocolate in a heatproof bowl over a pan of barely simmering water, stirring occasionally until just melted. remove from the heat and set aside for 10 mins to cool slightly.
3. return the sweet potato to the food processor and add the oil, eggs, yogurt, sugar, dates and vanilla; blitz until smooth. gradually add the cooled chocolate, whizzing until incorporated.
4. transfer the mixture to a large mixing bowl. sift over the cocoa and baking powder, then fold in the oat bran, ground and whole almonds, and a pinch of salt until just combined.
