Preheat the 300°F and line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of a stand mixer with a paddle attachment or a large mixing bowl with an electric hand mixer, cream together the softened butter and sugar on medium speed for about 1 minute, until it’s light and fluffy.
Gradually add the flour mixture to the creamed butter and sugar. Mix, scraping down the sides of the bowl as needed, until everything is fully combined. Stir in the chocolate chips. The shortbread dough will be thick and slightly crumbly.
Roll or scoop the cookie dough into 1-inch balls, placing them at least 2 inches apart on the prepared baking sheet. Lightly press each ball to flatten it slightly.
Bake in the preheated oven for about 20 minutes, until the edges are lightly golden. Remove from the oven and let the cookies cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
