Preheat the oven to 190C. Then line your baking tray with baking paper and grease with a little rapeseed oil.
Melt the chocolate with the oil in a saucepan very gently. Mix together.
Add the beetroot to your food processor and blitz to a paste then add in the chocolate, oil and eggs. Blitz again to combine. Finally add in the sugar, almonds, cocoa, baking powder and salt and whiz again until you get a batter. Fold in the walnuts.
Pour the batter into the tray and smooth down. Bake for 30 minutes then rest for 10 minutes to cool down before slicing.
