Grease and flour 8- x 4-inch loaf pan. Cream butter with an electric mixer or in a stand mixer. Gradually add 1 cup granulated sugar, beating until light and fluffy. Add eggs, 1 at a time, beating just until blended after each addition.

In a separate bowl, stir together flour, baking powder, and salt; add to butter mixture. Drizzle milk in and beat at low speed just until blended. Stir in 1 tablespoon lemon rind. Spoon batter into prepared loaf pan.

Bake at 350F for 1 hour or until a toothpick or knife inserted in center of bread comes out clean. Let cool in pan 10 minutes. Remove bread from pan, and cool completely on a wire rack.

Stir together powdered sugar and lemon juice until smooth. Use a bamboo skewer and poke holes all over the top of the bread and drizzle the icing over the top, so it will seep down into the holes and fill the bread with yummy goodness.

Stir together remaining 1 tablespoon lemon rind and 1 tablespoon granulated sugar; sprinkle on top of bread.
