This really is the Best Brownie Recipe ever! These homemade brownies are the perfect chewy fudge squares of chocolate. You'll never buy a boxed brownie mix again!
Preheat oven to 350 degrees F. Line a metal 9x9 pan with parchment paper.
Melt 10 tablespoons salted butter and pour into a large mixing bowl. Whisk in 1 cup granulated sugar by hand until smooth, 30 seconds.
Add in 2 large eggs and 2 teaspoons vanilla extract. Whisk 1 minute.
Melt 1/2 cup milk chocolate chips in a microwave in 30-second increments, stirring between each. Once melted and smooth, whisk into the brownie batter until combined and smooth.
Use a rubber spatula to stir in 3/4 cup all-purpose flour, 1/4 cup unsweetened cocoa powder, and 1/2 teaspoon salt until just combined. Stir in whole, unmelted chocolate chips.
Pour into prepared pan and smooth out.
Bake in the preheated oven for 30 minutes. Let cool in pan 30 minutes before slicing.
