Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, cream together the butter and sugar until light and fluffy. Beat in eggs one at a time, then stir in the vanilla.
• In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add to the creamed mixture and mix until just combined.
• Stir in the chocolate chips.
• Pour batter into the prepared pan and bake for 25-30 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let cool completely before cutting into bars.
