Author: Barbara Schieving


  • ½ cup butter
  • 2 cups brown sugar lightly packed
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • ½ teaspoon salt
  • 1 ¾ cup King Arthur Unbleached All- Purpose Flour
  • 2 teaspoons baking powder*
  • 1 ½ cups chocolate chips
  • 1 package white chocolate M&M's
  • 1 cup diced macadamia nuts


  • Lightly grease a 9 x 13-inch pan and preheat your oven to 350°F. Melt the butter in a medium-sized saucepan. Add the brown sugar, and stir until the mixture is smooth.
  • Remove the pan from the heat, pour the butter-sugar mixture into a medium-sized bowl, and allow it to cool to lukewarm. Whisk in the eggs one at a time. Stir in the vanilla extract and salt.
  • Whisk the flour and baking powder together, then add the dry ingredients to the sugar mixture, stirring to combine. Finally, fold in the M&M's and nuts.
  • Spread the mixture evenly in the pan, and bake the brownies for 30 to 35 minutes, until they're light brown on the edges and top


*I decreased the baking powder to 1 ½ teaspoons for high altitude baking.
