Ingredients:
1 cup unsalted butter
2 1/4 cups sugar
4 large eggs
1 1/4 cups cocoa powder
1 teaspoon salt
1 teaspoon baking powder
1 tablespoon vanilla extract
1 1/2 cups all-purpose flour
2 cups chocolate chips
Directions:
Preheat oven to 350°F (175°C). Grease and flour an 8×12 inch baking pan.
Melt butter in a medium saucepan over medium heat. Add sugar and stir to combine. Remove from heat.
Beat in eggs, one at a time, mixing well after each addition.
Stir in cocoa, salt, baking powder, and vanilla.
Blend in flour and chocolate chips.
Pour batter into prepared pan and smooth the top with a spatula.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Let the brownies cool in the pan before slicing into squares.
