Congo Bars are an amped up chocolate chip cookie bar with 2 types of chocolate to make them extra gooey!

  • 1 teaspoon kosher salt
  • 2 teaspoons baking powder
  • 2 1/2 cups all purpose flour
  • 2 cups semi-sweet chocolate chunks, or chopped chocolate
  • 1/2 cup milk chocolate chips

  2. In the bowl of your stand mixer fitted with the paddle attachment mix the butter and the light and dark brown sugars together for 2 minutes on medium speed. Add in the eggs, vanilla, salt and baking powder and mix for an additional minute on medium, scraping the sides of the bowl as necessary.
  3. Turn the mixer to low and add in the flour, mixing until just combined.
