Preheat over to 350°F. Use an 8-inch square baking pan. Butter or spray. I lined mine with foil.
Whisk together flour, cocoa, salt, baking powder and soda.
In a medium saucepan, melt butter over low heat. Remove the pan from the heat. Add the sugar and corn syrup, whisk to combine. Whisk in the eggs, one at a time. Whisk in vanilla.
Fold in the dry ingredients. Fold in the chocolate chips. Don't overmix.
Pour into pan, smooth the top. Bake until toothpick comes out clean, about 30 minutes.
