Preheat the oven to 375°F
Lightly grease a 9x5" loaf pan with butter or non-stick cooking spray.
In a large bowl, sift the flour, baking powder, sugar, and salt.
Pour in the beer and stir until just combined. Don’t overmix.
Spoon the batter into a loaf pan and gently smooth the top.
Drizzle the melted butter over the top.
Bake for approximately 45-50 minutes or until the top is a deep, golden brown and a knife inserted into the middle comes out clean or with a few moist crumbs.
Remove the bread from the oven and let rest for 20 minutes before slicing.
