Preheat oven to 350 degrees F. Line an 8-inch or a 9-inch metal pan with foil and grease foil or line with parchment.
Beat butter and sugar together in a small bowl using an electric mixer. Beat in the honey and vanilla. Add eggs one at a time, beating for 30 seconds after each egg. Beat in the salt.
Combine flour and cocoa. By hand (so as not to overbeat), stir the flour mixture into the batter, then stir in the chocolate chips. You can sprinkle more on the top if you like.
Spread the batter in the pan going all the way to the edges. Bake on center rack for 25 minutes for a 9-inch pan or up to 30 minutes for the 8-inch.
Let cool completely in pan.
Carefully lift brownies from pan and trim edges.
With a large knife, slice the brownie slab into 8 squares.
