Sieve the flour into a large mixing bowl. Add the cocoa powder, baking powder and cinnamon. Mix them together.
Then add the beetroot, egg, oil, vanilla extract and maple syrup to the large mixing bowl with the dry ingredients. Stir all the ingredients together until the mixture is runny.
Add the sultanas and stir to mix in well.
Now put 12 muffin cases into the mini muffin tray. Spoon the mixture into the cases. Ask an adult to help you put the tray into the oven.
After 12–15 minutes ask an adult to take the muffins out of the oven. Leave them to cool for at least 5 minutes.
When they have cooled put them on a plate and enjoy one! You can keep the extra muffins in a tin for later.
TOP TIP
If you have a food processor, ask an adult to use it to chop up the beetroot into small pieces. This is a lot less messy than grating it by hand.
