Creating a delightful Vanilla Poppyseed Cake is easy when you follow these clear and concise steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or two 9-inch round cake pans.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt.
3. Cream Butter and Sugar: In another bowl, cream the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Pour in the vanilla extract and mix until combined.
5. Combine Mixtures: Gradually add the dry ingredients to the creamed mixture, alternating with milk. Start and end with the dry ingredients. Stir until just combined.
6. Fold in Poppy Seeds: Gently fold in the poppy seeds and lemon zest if using, ensuring they are evenly distributed throughout the batter.
7. Pour Batter: Pour the batter into the prepared pan(s), smoothing the top with a spatula.
8. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted into the center comes out clean.
9. Cool Down: Once baked, remove the cake from the oven and allow it to cool in the pan for 20 minutes. Then, transfer to a wire rack to cool completely.
10. Dust with Powdered Sugar: Before serving, dust the top with powdered sugar for an elegant finish.
