Preheat your oven to 175°C and butter 3 cake pans. (Butter over Oil every time).
In a bowl, whisk together the flour, baking powder, baking soda, and salt.
In your stand mixer (or a separate bowl if you are doing it by hand) add the butter and sugar and whisk it together at high speed.
Lower the speed, add the Eggs and Vanilla Extract, and bring the speed back up to high.
When everything is mixed thoroughly, reduce the speed to low and slowly add the dry ingredients from Step 2. When they are all combined, add the Milk, Lemon Juice, and Lemon Zest.
When everything is combined, pour into the three buttered cake pans, and bake for 25 minutes. When they are done, flip them onto a cooking rack.
When they get to room temperature, wrap them individually in cling film and place in the refrigerator for 30 minutes while you make the Lemon Frosting.
