Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
In a large bowl, cream together the softened butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the butter mixture, mixing just until combined.
Pour the batter into the prepared pan and spread evenly.
Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool slightly before slicing and serving.
