01 - Preheat oven to 350°F. Grease a 10-cup Bundt pan with butter and dust lightly with flour, tapping out any excess.
02 - Using an electric mixer, beat softened butter and granulated sugar together until pale and fluffy, about 3 to 4 minutes.
03 - Add eggs one at a time, beating well after each addition to ensure full incorporation.
04 - In a separate bowl, whisk together flour, baking powder, and salt until evenly combined.
05 - Add dry ingredients to butter mixture in three parts, alternating with milk; begin and end with dry ingredients. Mix until just combined.
06 - Gently fold in lemon zest, lemon juice, and vanilla extract until uniformly distributed.
07 - Pour batter evenly into prepared Bundt pan, smoothing the surface.
08 - Bake for 45 to 50 minutes, or until a skewer inserted into the center emerges clean.
09 - Allow cake to cool in the pan for 10 minutes, then invert onto a cooling rack and cool completely.
10 - Whisk powdered sugar with 2 tablespoons lemon juice until smooth; add more juice as needed to achieve pourable consistency.
11 - Drizzle lemon glaze over cooled cake, letting it cascade down the sides.
