Preheat oven to 350°F. In a large bowl sift together flour cocoa powder salt and baking powder. Set aside. In a medium saucepan on medium-high heat melt butter. Remove from heat. Add sugar eggs vanilla and 1/2 cup honey to melted butter. Fold dry ingredients into butter mixture being careful not to over mix. Spread into a greased 8 x 8" baking pan and bake for 22-25 minutes or until a toothpick inserted in the middle comes out clean. Remove from oven. Cool completely. To make the glaze place milk and remaining honey into a small saucepan and bring just to a boil. Remove from heat and whisk in icing sugar until smooth. Drizzle glaze over cooled brownies.
