Preheat your oven to 350°F (180°C) and grease a muffin pan or line it with cupcake liners.

In a large bowl, whisk together 2 eggs, 1/2 cup melted unsalted butter, 3/4 cup milk, and 1 tablespoon granulated sugar until frothy.

Sift in 2 cups of all-purpose flour, 1 tablespoon baking powder, and 1/2 teaspoon salt to the wet ingredients and mix gently.

Fold in 1 cup chopped cooked ham, 1 cup shredded cheddar cheese, and 1/4 cup finely chopped scallions.

Divide the batter among muffin cups, filling each nearly to the top.

Bake for 22-25 minutes or until tops are golden and a toothpick comes out clean.

Cool in the pan for 5 minutes before transferring to a wire rack.
