Preheat oven to 375 degrees Fahrenheit.
Line a 24-count muffin tin with 18 cupcake liners.
In a medium-sized bowl, mix together the flour, baking powder, and salt.
In a large bowl, combine the eggs, sugar, milk, and butter until combined.
Mix the dry ingredients into the wet ingredients.
Slowly fold in the blueberries, and mix all the ingredients until combined. The batter will be thick, but workable.
Use an ice cream scoop to fill your cupcake liners 3/4 way. I made 18 muffins but this could vary depending on which size muffin tin you use.
Sprinkle with the sugar and nutmeg topping.
Bake for 17-20 minutes. The tops should be springy, and not wet. A toothpick inserted into the center of the muffins should come out clean.
Allow muffins to cool for ten minutes before enjoying.
