Creating Irish Potato Bread is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper.
2. Combine Ingredients: In a large bowl, mix the mashed potatoes, flour, baking powder, and salt until well combined.
3. Add Butter: Pour in the melted butter and milk. Stir until a dough forms.
4. Knead the Dough: Transfer the dough onto a floured surface. Knead gently for about 1-2 minutes until smooth.
5. Shape the Bread: Form the dough into a round shape, about 1-inch thick. Place it on the prepared baking sheet.
6. Score the Top: Use a sharp knife to score an “X” on top of the bread. This helps it cook evenly.
7. Brush with Egg (Optional): If desired, brush the top with a beaten egg for a glossy finish.
8. Bake: Place in the oven and bake for 20-25 minutes, or until the bread is golden brown and sounds hollow when tapped.
9. Cool: Remove from the oven and let cool slightly on a wire rack before slicing.

By following these steps, you’ll create a delicious loaf of Irish Potato Bread that is sure to impress!
