Take butter in a mixing
bowl and cream it with an electric beater till light. Add yogurt and beat again. Add beetroot juice and beat well.
Sift together flour,
baking soda, baking powder and salt into the butter mixture. Fold in well to make a smooth batter.
Fill a piping bag with
the batter.
Place individual silicon
moulds on a baking tray and line them with fancy paper liners. Pipe the batter into the moulds, filling them upto ¾. Tap lightly.
Keep the tray in the
preheated oven and bake for 20 minutes. Remove from the oven and cool down to room temperature.
To make icing, take
feta cheese in a bowl. Add cream and whisk till well combined and smooth.
Fill this mixture into
another piping bag fitted with a star nozzle.
Demould muffins with
the paper liners and keep them on a serving platter. Pipe icing rosettes on top and serve.
