Preheat the oven to 350 degrees Fahrenheit. Spray a 9 x 5-inch loaf baking pan with nonstick cooking spray.

Whisk together 2 cups all-purpose flour, 1 tablespoon granulated sugar, 1 tablespoon baking powder, 1 ½ teaspoons garlic powder, ½ teaspoon onion powder, and ¾ teaspoon salt in a large bowl.

Combine 1 cup milk and 1 large egg, then stir the milk mixture into the flour mixture along with ¼ cup melted unsalted butter until combined.

Stir in 2 cups shredded cheddar cheese, then pour the batter into the prepared baking pan.

Bake for 35-40 minutes, until baked through and a toothpick comes out clean from the center of the loaf. If you'd like the top a little darker, turn the oven to broil on HIGH for 1-2 minutes.

Just before the loaf comes out of the oven, stir together ¼ cup melted salted butter, ¼ teaspoon garlic powder, ¼ teaspoon onion powder, and 1 tablespoon fresh chopped parsley.

Brush the garlic butter over the top of the bread as soon as it comes out of the oven. Let the bread rest for about 10 minutes before removing from the pan and slicing.
