Start by preheating your oven to 350 degrees. Make sure to take your loaf pan and grease it with nonstick cooking spray.
Now in a larger bowl you will add in your sifted flour, baking powder, salt, garlic powder, and your sugar. Stir it around to mix in the ingredients.
Pour in your beer and stir until it begins to form soft dough.
Stir in your shredded cheddar cheese.
Pour the dough into your loaf pan. Then bake for 45-55 minutes or until the bread is fully cooked. Stick a toothpick in and if it comes out clean it is done.
Remove from the oven and then allow the bread to cool in the pan for 5-10 minutes on a cooling rack.
In a small bowl, add in your melted butter and garlic powder and parsley. Stir together and then brush over the top of the bread. Slice and serve.
