Beat butter with sugars until light and fluffy; add vanilla and egg and beat to combine. Add the flour, cocoa powders, salt, baking soda, and baking powder; mix to combine and slowly add the beer; beat just until combined; fold in chocolate chips; refrigerate the dough until firm (about 15 minutes).
