Preheat the oven to 350℉. Line a 9x9-inch baking pan with parchment paper.

In a mixing bowl, whisk together the melted butter and sugar until combined. Add the vanilla extract and eggs and whisk well. Lastly, add the flour, salt, and cocoa powder and whisk until smooth. Pour into the prepared baking pan. Bake in the preheated oven for 25-30 minutes or until no longer jiggly in the center.

Let cool completely before lifting the brownies out of the pan using the parchment paper edges to assist. Chop into chunks of your desired size. Store brownie chunks in the refrigerator to last longer. Enjoy!
