Preheat your oven to 180°C. Grease a 12 hole muffin tray with butter or cooking spray.
Place the butter,sugar and the vanilla in a bowl of a stand mixer fitted with a paddle attachment. Beat the butter and sugar together for 3-5 minutes,until it becomes pale and creamy.
With the motor running on medium speed,drizzle the beaten eggs in a stream. Beat for another minute until light and fluffy.
In a separate bowl,sift together the flour,baking powder,cream of tartar,bicarb soda and nutmeg.
With the mixer running on low speed,add 1/3 of the flour mixture,followed by half of the greek yoghurt,then another 1/3 of the flour,the rest of the yoghurt then finishing with the flour. Only mix until just combined.
You will have a fairly stiff batter. If it is a particularly hot and humid day,it might be worth refrigerating the mixture for 15 minutes,otherwise proceed immediately.
Combine the caster sugar and cinnamon in a shallow bowl. Taking nectarine sized balls of batter (using an ice cream scoop will help with this),drop them into the cinnamon sugar and coat all over. As you turn the ball around in the cinnamon sugar,it should form a barrier that makes it easier to handle. Drop each ball into a hole in the muffin tray.
Bake for 20-22 minutes,or until golden brown.
