Combine the water, butter and milk.
Place mixture in the microwave or in a saucepan over medium-heat and heat until the mixture reaches 95-115F. If it is hotter, allow it to cool slightly before proceeding with the recipe.
Stir together 3 1/2 cups of the flour, salt, sugar and instant yeast in a large bowl or the bowl of your stand mixer.
Add the warm liquid mixture and knead for 6-8 minutes until a soft ball forms and pulls clean away from the sides of the bowl. Add the additional 1 cup flour, as needed
Place the dough in a greased bowl and cover with plastic wrap and a clean towel for 15 minutes.
Grease a 9” x 13” casserole dish and set aside.
Punch down the dough and divide into 12 equal sized balls of dough.
Place the balls of dough in the greased casserole dish and re-cover with plastic wrap and towel for another 15 minutes.
Preheat your oven to 400F
Remove plastic wrap and towel from the casserole dish and place the dish in the oven for 15 minutes, until puffed and golden brown on top.
If brushing with butter, brush halfway through baking with 1 Tablespoon of melted butter and then again after baking.
