Preheat your oven to 325°F (160°C) and grease a bundt pan.

In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.

Add the eggs one at a time, mixing well after each addition.

Stir in the vanilla extract.

In a separate bowl, combine the flour, baking powder, baking soda, and salt.

Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk.

Mix until just combined and pour the batter into the prepared bundt pan.

Bake for 60 minutes or until a toothpick inserted into the center comes out clean.

Prepare the glaze by whisking together the milk and powdered sugar.

Let the cake cool for 10 minutes before inverting onto a serving plate and drizzling with the glaze.
