How to Make It
Preheat oven to 350° F. Spray a rimmed baking sheet with cooking spray and set aside.
In a large bowl, whisk together the flour, baking powder, baking soda, and salt and set aside.
In a large bowl, using and electric mixer, beat the butter and sugars, starting on low and then raising to medium-high, until light and fluffy, 2 to 3 minutes. Beat in the eggs and vanilla.
Reduce mixer speed to low and gradually add the flour mixture, mixing until just combined (do not overmix) and scraping down sides of the bowl, as needed. Fold in the chopped chocolate and mix until evenly incorporated.
Spread dough into prepared baking sheet using a spatula (but press with your hands to help get in the corners) all the way to the edges of the pan.
Bake on center rack until light golden, 8 to 10 minutes. Scatter hugs and kisses evenly over top and return to oven until cookie edges are brown, top is golden, and hugs and kisses are half melted, 8 to 10 minutes more.
Let cool and cut into 24 rectangles.
