1.Preheat oven to 350 degrees. Spray an 8 X 8 square pan with cooking spray. Set aside.
2.In a medium saucepan, (I used a nonstick) On low to medium heat. Melt butter or margarine. Take off heat, add sugar and mix well. Make sure the egg mixture is cooled down. Add in eggs one at a time. Mix again. Add vanilla, salt, baking powder and flour. Gently mix well with a rubber spatula. Make sure all the dry ingredients are mixed into the wet. Try not to over mix though. When all is incorporated, pour into prepared pan.
3.Bake for 20 to 30 minutes. Check after 20 minutes. Middle should look set and a toothpick should come out with moist to dry crumbs. If not yet done, put back into oven and bake until done. Test again.
4.Cool in pan on a wire rack for at least 20 to 30 minutes. It’s easiest to cut up brownies with a plastic knife. Brownies don’t usually stick to the plastic knife.
