In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt.

In a small saucepan, gently heat the milk until it's warm but not boiling.

Add the melted butter to the warm milk and stir to combine.

Pour the milk mixture into the dry ingredients and stir until just combined.

Lightly flour your countertop and turn the dough out onto it, knead gently a couple of times.

Pat the dough to about 1-inch thick.

Using a round cutter, cut out circles from the dough.

Preheat your skillet over medium-low heat and cook the muffin rounds for about 5-7 minutes on each side until golden brown.

Remove the muffins from the skillet and let them cool on a kitchen towel.
