In a large mixing bowl, mix together sourdough starter, milk and eggs until well combined.
Pour in the melted butter and stir through the starter mixture.
In a separate bowl, mix together flour, salt, baking powder, cheddar cheese, parmesan cheese and garlic powder.
Now pour the dry ingredients on top of the liquid ingredients.
Mix until it forms a thick batter.
Heat up your waffle iron and spoon mixture into the iron. Cook until golden and cripsy. This recipe makes 5 to 6 generous sized sourdough cheese waffles.
