In a large bowl, combine flour, cornmeal, salt, and baking soda.
In a large jug whisk together milk, yoghurt, butter, sugar and eggs.
Pour the liquid over dry ingredients and mix until mixed well.
Scoop 1 tbsp of the mixture in to each muffin case and place 1 piece of hotdog in to the centre, cover it with a little bit of batter.
Place in the oven to bake for around 10 minutes, or until golden brown.
