Preheat your oven to 350°F (175°C).

Melt 3 tablespoons of unsalted Irish butter in a small saucepan over low heat and brush it generously inside a 9x5 loaf pan.

In a large mixing bowl, whisk together the flour, sugar, baking powder, salt, garlic powder, and onion powder.

Add the shredded Irish cheddar cheese to the dry mixture and stir gently until well-coated.

Create a well in the center of the dry ingredients and pour in the beer. Stir until just combined, being careful not to overmix.

Pour the thick batter into the prepared loaf pan, spreading it evenly.

Drizzle the remaining melted butter over the top of the batter in the loaf pan.

Place the loaf pan in the oven and bake for 45-50 minutes until a toothpick inserted comes out clean.

Prepare the garlic butter topping by melting 2 tablespoons of unsalted butter, then stir in chopped parsley, garlic powder, and a pinch of salt.

Once the bread is baked, brush the garlic butter topping generously over the warm bread.

Let the bread cool in the pan for about 10-15 minutes before transferring to a wire rack to cool completely.
