Place the muffin pan in the oven to heat at 450° while you prep the dough.
Combine flour, cornmeal, baking powder and salt in a large bowl.
Cut the butter into the flour with a fork or pastry blender.
Stir in goat cheese and rosemary.
Add the milk, stirring by hand. Work it over till the dough thickens up a bit.
Pull the pan from the oven and spray with cooking spray. Spoon the dough into the pans.
Bake for about 8 minutes.
Pull the biscuits out of the oven and brush with melted butter and sprinkle with Parmesan.
Bake another minute or two.
Brush with melted butter again before serving.
Notes
Note: You can also use a regular size muffin tin for 12 biscuits, a small iron skillet or ramekins. One recipe will make a 6″ skillet + 3 - 4″ ramekins
