Preheat your oven to 350°F (175°C).

Grease your 9-inch round cake pan with butter or cooking spray.

In a bowl, whisk together the flour, baking powder, baking soda, and salt.

In a large mixing bowl, beat the softened butter and sugar until light and fluffy.

Mix in the eggs one at a time, followed by the vanilla extract.

Gradually add the dry mixture and buttermilk to the creamed mixture, starting and ending with the dry ingredients.

Gently fold in the chocolate chips using a rubber spatula.

Pour the batter into the prepared pan and smooth the top.

Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.

Let your cake cool in the pan for 10 minutes before transferring it to a wire rack for complete cooling.
