Preheat oven to 350° and grease a muffin pan.
Cream together the butter and sugar. Then add the egg and mix well.
Add flour, baking powder, salt, nutmeg, and milk. If you are using salted butter (sweet cream) then reduce salt to ¼ t.
Stir together until everything is incorporated but don’t over mix.
Divide the batter into 12 muffins. Bake for about 20 minutes or until golden brown around edges of each muffin.
For the coating melt the butter and mix 1 t. cinnamon with ⅓ cup of sugar. Have this ready when the muffins are done cooking.
Immediately after removing from the oven, dip each muffin quickly in the melted butter and then roll in the sugar.
