Preheat your oven to 350°F (175°C).
Grease two 9-inch cake pans.
In a bowl, whisk together the flour and baking powder.
Using a stand mixer, beat butter and sugar until fluffy.
Add eggs one at a time, then mix in vanilla extract.
Gradually alternate adding flour mixture and milk, mixing until just combined.
Divide batter evenly between pans and bake for 25-30 minutes.
Let cool before frosting with your favorite icing.
