Whisk flour cocoa powder salt baking powder and baking soda in a bowl. Beat 1 cup butter and white sugar in a separate large bowl with an electric mixer on medium speed until mixture is creamy. Beat eggs and 2 teaspoons vanilla extract into butter mixture.

Stir half the flour mixture into wet ingredients followed by milk; stir remaining flour mixture into dough. Drop dough by tablespoonfuls onto baking sheets. For 25 whoopie pies make 50 cookies.

Bake cookies in the preheated oven until set and lightly browned about 10 minutes. Let cool completely.
