Prepare the Oven and Pan: Preheat your oven to 325°F (165°C). Grease a 9x5-inch loaf pan or Bundt pan with butter or non-stick spray, then lightly dust with flour.
Cream Butter and Sugar:In a large mixing bowl, use an electric mixer to beat the softened butter and sugar together until light and fluffy (about 3–5 minutes).
Add Eggs One at a Time: Crack the eggs into the mixture one at a time, beating well after each addition. This ensures a smooth and even batter.
Mix Dry Ingredients:In a separate bowl, sift together the flour, baking powder, and salt.
Alternate Wet and Dry Ingredients:Gradually add the dry ingredients to the butter mixture, alternating with the milk. Begin and end with the dry ingredients, mixing just until combined after each addition.
Add Vanilla Extract: Stir in the vanilla extract for a rich, aromatic flavor. If using optional lemon zest or flavoring, add it now.
Pour Batter into Pan: Transfer the batter into the prepared pan, smoothing the top with a spatula for even baking.
Bake the Cake: Place the pan in the preheated oven and bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
Cool the Cake:Remove the cake from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a cooling rack to cool completely.
Serve and Enjoy: Slice the pound cake and serve as is, or pair with whipped cream, fresh fruit, or your favorite toppings for a delightful treat.
