Preheat oven to 350 degrees F
Grease and flour an 8 inch square pan, or spray a muffin tin with cooking spray.
In a large saucepan, melt 1/2 cup butter. Remove from heat, and stir in sugar, and cocoa. Add eggs, and 1 teaspoon vanilla. Stir in 1/2 cup flour, salt, and baking powder. Spread batter into prepared pan (or cupcakes no more than 12)
Bake in preheated oven for 25 to 30 minutes for 8x8pan and 20-22 minutes for muffin tin. Do not overcook.
**By the way I have been wanting to buy one of the brownie baking dishes, that are “all ends” or corners or sides…. ( that is my favorite part, but I am no longer going to buy one…) I found out that a muffin/cupcake pan is perfect, and that I don’t need one extra pan… So give it a try if you like brownie edges! (and they are perfectly portioned!)
