Line a 20cm (8 inch) square tin with baking paper.
Roughly chop 50g walnuts (or pumpkin seeds) in a food processor.
Add 100g chopped dates (or raisins) and 500g cooked beetroot to the processor.
Pulse until you have a thick paste, stopping to scrape the sides down once or twice.
Scrape out into a bowl and add 130g plain flour, 1 teaspoon baking powder, ½ teaspoon bicarbonate of soda, 3 tablespoons of cocoa powder and 3 tablespoons maple syrup (if using). Mix well.
Transfer to your prepared cake tin and smooth the top.
Bake in the oven for 40-45 minutes or until firm to the touch and a skewer comes out clean.
Allow to cool in the tin for 5-10 minutes before carefully removing and cooling on a wire rack.
To decorate, optional
Beat the tahini with a fork, gradually adding the drops of beetroot juice until it is pink in colour. Take care not to make it too watery.
Drizzle over the brownies and leave to set for a few moments.
Notes
*Medjool dates are much stickier than other varieties. If you are using a different type of date and it seems dry you might need to soak them in hot water for 20 minutes before proceeding with this recipe.
