Preheat oven to 400 degrees F. Line a 12-cup muffin tin with paper liners or spray with a non-stick cooking spray.
In a large bowl, whisk together the flour, sugar, baking powder and salt.
In a medium bowl, whisk together the milk, butter, honey and egg.
Pour the wet ingredients into the dry ingredients and, using a rubber spatula, fold together until no dry ingredients remain.
Divide the batter evenly between the muffin cups. Bake for 12 to 15 minutes, or until a toothpick inserted in the center comes out clean. Cool in the pan for 5 minutes, then remove to a wire rack. Serve warm or at room temperature. Leftovers can be stored in an airtight container at room temperature for up to 3 days.
