Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
In a large mixing bowl, cream the softened butter and sugar together until light and fluffy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
Divide the batter evenly between the prepared pans and smooth the tops.
Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center of the cakes comes out clean.
Allow the cakes to cool in the pans for about 10 minutes, then remove them from the pans and transfer to a wire rack to cool completely.
Once the cakes are cool, you can frost and decorate them as desired for your birthday celebration. Enjoy your homemade birthday cake!
