Preheat your oven to 350°F (175°C). Grease and flour two round cake pans.

In a medium bowl, whisk together flour, baking powder, and salt.

In a large bowl, cream the softened butter and sugar until light and fluffy (about 3 minutes).

Add eggs one at a time, mixing well after each addition. Stir in lemon juice and zest.

Gradually alternate adding dry ingredients with milk to the wet mixture; mix until just combined.

Pour batter into prepared pans and bake for 25-30 minutes or until a toothpick comes out clean. Cool before serving.
