Step 1

Heat the oven to 375°. Butter the bottoms (only) of a standard 12-cup muffin tin and set aside.

Step 2

To a large mixing bowl, add the flour, sugar, baking powder, salt, and nutmeg and whisk together.

Step 3

In a medium-size bowl, add the egg and whisk until frothy. Add in the milk, melted and cooled butter, and vanilla extract and continue whisking until blended.

Step 4

Make a well in the dry ingredients and pour in the wet ingredients.

Step 5

With a spatula or wooden spoon, mix the batter just until it's just evenly blended, then scoop it evenly into the muffin pan.

Step 6

Bake the muffins on the center rack for 15 minutes. Then rotate the pan and bake for an additional 5 to 7 minutes.

Step 7

Remove from the oven and let cool for approximately 5 minutes or until cool enough to handle, then remove the muffins from the pan.

Step 8

While the muffins are cooling, prepare the topping by mixing the sugar and cinnamon in a small bowl.

Step 9

In a small microwave safe bowl, melt the butter and set next to the cinnamon sugar mixture.

Step 10

Working one muffin at a time, quickly dip the tops in the melted butter and then in the cinnamon sugar, rolling each muffin in all directions to cover the entire top.
