1️⃣ Preheat Oven and Prepare Pan:

Preheat your oven to 350°F (175°C).
Grease a 9×5-inch loaf pan and line it with parchment paper for easy removal.

2️⃣ Mix Dry Ingredients:

In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.

3️⃣ Cream Butter and Sugar:

In a large mixing bowl, beat the unsalted butter and granulated sugar using an electric mixer on medium speed until light and fluffy (about 2-3 minutes).

4️⃣ Add Eggs and Flavorings:

Add the eggs to the butter mixture one at a time, beating well after each addition.
Mix in the lemon zest, lemon juice, and vanilla extract until well combined.

5️⃣ Combine Dry and Wet Ingredients:

Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. Be careful not to overmix.

6️⃣ Bake the Cake:

Pour the batter into the prepared loaf pan, smoothing the top with a spatula.
Bake for 55-60 minutes, or until a toothpick inserted into the center comes out clean.

7️⃣ Prepare the Lemon Glaze:

While the cake is baking, whisk together the powdered sugar, lemon juice, and milk in a small bowl until smooth.

8️⃣ Glaze the Cake:

Allow the cake to cool in the pan for about 15 minutes before transferring it to a wire rack.
Drizzle the lemon glaze over the warm cake.
Garnish with lemon slices and zest, if desired.
