Preheat the oven to 325 degrees and grease a loaf pan with nonstick cooking spray.

Whisk together the flour, baking powder, and salt in a medium bowl. Set aside.

In a separate bowl, beat together the butter and sugar until light and fluffy.

Add the eggs, one at a time, beating between each addition.

Beat in the vanilla extract.

Add half the flour mixture to the bowl and beat to mix, then add half the milk and beat to mix. Add the remaining flour, then the remaining milk, beating between each addition.

Fold in the mini chocolate chips.

Pour the batter into the prepared pan and bake for 55 to 65 minutes, until a toothpick inserted into the center comes out clean.

Allow to cool in the pan for 10 minutes, then transfer to a wire cooling rack to cool completely.
