• All-Purpose Flour: is the base of the brownies and provides them with structure.
• Salt: enhances the rich chocolate flavor and balances the sugar.
• Baking Powder: is the leavening agent that gives the brownies a slight lift and fudgy texture.
• Unsweetened Cocoa Powder: is where the deep, rich chocolate flavor comes from. Try black or extra dark cocoa powder for a uniquely tasty flavor.
• Granulated Sugar: adds sweetness and helps create that classic crackly brownie top.
