Sift the flour and baking powder together into the batter and fold in. Gently stir in the sesame seeds and grated beetroot until well combined.

Divide the mixture between 10 large muffin cases and place into the preheated oven. Bake for about 20 minutes, until a skewer inserted into the cake comes out clean.
