Preheat your oven to 350°F and grease a bundt pan or 9x13 baking dish.
In a large bowl, cream the butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each.
Stir in the lemon juice, zest, and vanilla extract.
In a separate bowl, whisk together flour, baking powder, and salt.
Add dry ingredients to the wet mixture, alternating with milk. Start and end with dry ingredients.
Pour batter into the prepared pan and smooth the top.
Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pan for 10 minutes, then turn out onto a wire rack to cool completely.
If you’d like, drizzle with lemon glaze made of powdered sugar and lemon juice.
