Preheat the oven to 350°F; grease a 10-12 C bundt pan.
Place the butter in a bowl, and beat until it’s smooth. Beat in the sugar until creamy.
Beat in the eggs one by one, scraping the bottom and sides of the bowl midway through. As you add the final couple of eggs, the mixture will begin to look curdled; that’s okay.
Add the baking powder and salt to the batter, stirring just to combine. Stir the vanilla extract into the milk; set aside.
Add half of the flour to the batter, beating gently to combine.
Gently mix in the milk; then the other half of the flour.
Pour into pan and bake for 50 to 60 minutes, until it’s starting to brown, appears set on top, and a toothpick inserted into the center comes out clean.
Remove the cake from the oven, and gently loosen its edges. Turn the pan over onto a cooling rack. After 10 minutes, lift the pan off the cake, and allow it to cool completely.
