Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a bowl, cream together the butter and sugar until light and fluffy.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
In another bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the butter mixture, alternating with the milk, beginning and ending with the dry ingredients.
Fold in the chocolate chips.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 50 minutes or until a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
