Preheat oven to 180 c / 350 F. Grease your muffin tray with butter.

Melt the butter and let cool.

Mix together the brown sugar and cinnamon . Keep aside.

Whisk together the flour, granulated sugar , baking powder and salt.

Add the milk, yoghurt and three tablespoons of the melted butter. Mix until it forms a smooth dough. You may need to use your hands.

Make small balls of the dough (about a cm in size) , dip in the butter. Tap off excess butter into the bowl.

Roll in the cinnamon sugar.

Place into the greased muffin trays. You don't have to squish them together. They just need to be touching. Repeat with all the dough.

Bake in the preheated oven at 180 C/ 350 F for 18-20 minutes.They will increase a little in size and turn a dark brown. Cool in the tray for five minutes and then nudge them out (by running a knife along the cavity) .

When they are out of the oven, prepare the glaze by mixing together the milk and icing sugar until smooth. Add more milk if needed to achieve desired consistency.

Pour over warm muffins and serve!
