Preheat the oven to 350F. Butter and flour a 9x13 inch baking pan. I used a large bundt cake pan but feel free to use whatever pan you prefer to use.

Heat the milk and 3 sticks of butter in a saucepan over medium heat. Once the butter has melted and the mixture just comes to a boil, remove it from the heat. Set aside to cool.

In a bowl, combine together the flour and baking powder. Stir to combine and set aside.

In a stand mixer fitted with a paddle attachment, beat together the sugar and eggs in medium speed for 4 minutes until thick and pale yellow. Add the vanilla extract and mix to combine.

Set the mixer to low and alternately add the dries and milk mixture, beginning and ending with the flour. Pour the batter into the prepared baking pan and bake for 35-40 minutes until golden brown and a skewer comes out clean when inserted in the center. Let it cool in the pan before removing.
