Heat oven to 200°C, fan assisted.
Stir all the dry ingredients but the strawberries in a large bowl.
In a smaller bowl whisk the yogurt with the melted butter and a beaten egg.
Now pour the liquid ingredients into the bowl of dry ingredients and fold gently until you have a smooth batter. Finally add the chopped strawberries.
Line 12 muffin tins with baking paper or paper cups, fill them with the strawberry batter and bake in a hot oven for about 20 minutes, until golden and well puffed.
