Preheat your oven to 350°F (175°C) and grease a bundt pan.
In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.
Add the eggs one at a time, mixing well after each addition.
Stir in the sour cream and vanilla extract until well combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Pour the batter into the prepared bundt pan, smoothing the top.
Bake in the preheated oven for about 60 minutes or until a toothpick comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack.
Let it cool completely before serving, optionally dusted with powdered sugar.
