Preheat the oven to 350°F. Line two cookie sheets with parchment paper and set aside.

Combine the flour, cocoa powder, baking soda, and salt in a small bowl. Gently stir with a whisk to evenly distribute. Set aside.

Fit a stand mixer with a paddle attachment and cream the butter, both sugars, and vanilla until light and creamy. Add the eggs and blend until entirely incorporated. Scrape down the sides of the bowl. Add the dry ingredients and blend on low speed until the ingredients are just combined.

Use a tablespoon to place the dough onto the prepared cookie sheets. Do not flatten the cookie dough balls. Bake for 12 to 14 minutes. Do not over-bake.

Remove the cookies from the oven and let them cool for 5 minutes. Then, gently press a Kiss into the middle of every cookie. Cool for 15 to 20 more minutes then serve warm. Or, let the cookies cool entirely before serving or storing.
