Mixed Berry Greek Yogurt Muffins - Julia's Album
Bake for 20 min at 180 C (fan forced). Don't overmix the batter initially, as you have to mix the berries/whatever in later on! (Can use 1 cup choc chips instead.) Streusel topping -- only need a little. Brown sugar and icing sugar mix, more cinnamon, less flour, less butter.
