Two1.55-ouncemilk chocolate bars (like Hersheys).chopped into 1/4-inch pieces
Instructions
Preheat oven to 325 degrees F. Spray an 8x12-inch baking pan with nonstick spray. If you don't have an 8x12-inch pan, bake them in a 9x9-inch pan. They will be a little thicker, and the baking time may need to be increased slightly.
In a medium bowl whisk together the flour, baking powder and salt; set aside.
Melt the butter in medium saucepan over medium heat; add cocoa and cook, stirring constantly, until consistency of chocolate sauce. Remove from heat. Pour the hot mixture into a bowl and let cool slightly. Whisk in the sugar and then whisk in the eggs until blended and smooth. Stir in the flour mixture. Stir in the vanilla and chocolate pieces.
Pour the batter into the prepared pan. Bake 20 to 25 minutes or until a toothpick inserted in the center comes out clean. Let cool before cutting into bars.
Notes
*Try freezing the chocolate bits so they don't melt too much in the brownie batter.
