Best Easy Brownies require just 1 bowl, no mixer, and take less than an hour to make! They're tall, fudgy, and chewy with that thin shiny crust on top and tons of chocolate flavor.
Preheat oven to 350 degrees F. Line a metal 8-inch square pan with parchment paper.
In a large microwave-safe bowl combine the chocolate and butter. Microwave in 30-second bursts, stirring between each burst, until the mixture is melted and smooth. Add the sugar to the hot butter mixture and whisk vigorously until combined. Allow to cool until just barely warm.
Add in eggs, yolk, and vanilla extract and whisk for about 1 minute, or until very well combined. This helps create that shiny crust on top.
Use a rubber spatula to stir in flour, cocoa powder, and salt until just combined. Stir in the chocolate chips.
Pour into prepared pan and smooth out. Bake in the preheated oven for 25 to 30 minutes, or until a toothpick entered in the center comes out with moist crumbs. Let cool in pan 30 minutes before slicing.
*You can make this recipe even easier by using chocolate chips instead of chopping baking chocolate. Simply use 2/3 cup semisweet chocolate chips in place of the chopped chocolate. Just be sure to use high quality chips!
*Be sure to weigh or use the spoon-and-level method to measure your flour & cocoa. Too much will lead to dry, dense, or cakey brownies.
