Preheat the Oven: Start by preheating your oven to 350°F (175°C) while you prepare the batter.
Cream the Butter and Sugar: In a large mixing bowl, cream together the softened butter and granulated sugar until the mixture is light and fluffy.
Add Eggs: Beat in the eggs, one at a time, ensuring each one is fully incorporated before adding the next.
Mix in Lemon Zest and Juice: Stir in the lemon zest and juice, allowing the fresh citrus flavor to infuse the batter.
Combine Dry Ingredients: In a separate bowl, combine the flour, baking powder, and salt. Whisk until blended.
Mix Wet and Dry Ingredients: Gradually add the dry mixture to the wet ingredients, alternating with milk. Mix until just combined—don’t overmix!
Prepare the Pan: Pour the batter into a greased 9x5 inch loaf pan, smoothing the top with a spatula.
Bake the Cake: Bake in the oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
Cool the Cake: Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Add Finishing Touches: Once cooled, dust with powdered sugar if desired, and serve!
