Add the grated beetroot and mashed banana and mix lightly with a spoon until just combined. Do not over-mix; the mixture should still be lumpy.
Spoon mixture into greased muffin pans, filling each three-quarters full. Bake for about 20 minutes until light brown. Turn out onto a wire rack to cool.
Dust with icing sugar before serving.
VARIATIONS
Carrot Muffins: Substitute the beetroot with grated carrots.
Dried Fruit Muffins: Reduce sugar to 80 ml (1/3 cup) and add 200 ml (¾ cup) coarsely chopped cherries or any other dried fruit of choice. Makes 12 muffins.
TIP
The beetroot will colour the mixture completely red, but once baked, the muffins will be lighter in colour.
