Add eggs one at a time, making sure each egg is fully incorporated in batter before adding the next one. Stir in milk and vanilla.

Add dry ingredients to wet ingredients and beat with an electric mixer on medium speed for 2 minutes or until the batter is smooth. Pour batter into prepared pan. Bake for 1 hour at 350 degrees F (175 degrees C).

Insert a knife into the center of the cake. If it comes out clean, the cake is made. Allow cooling completely before removing from pan.
