Preheat oven to 375 °F (190 °C). Grease and lightly flour a 9×5‑inch loaf pan.

In a large bowl, whisk together flour, baking powder, salt, garlic powder, and parsley. Stir in half the cheddar cheese.

In a separate bowl, whisk milk, egg, and melted butter until smooth.

Pour wet ingredients into dry ingredients, stirring until just combined—do not overmix.

Fold in the remaining cheddar cheese.

Transfer batter to the prepared pan and smooth the top.

Bake 45–50 minutes, until a toothpick inserted in the center comes out clean or with just a few moist crumbs, and the top is golden.

Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool another 10 minutes before slicing.
