Servings 15 very large brownies


  • ¾ cup unsalted butter
  • 8 oz 50% dark chocolate* chopped
  • ½ cup peanut butter
  • 1 ½ cups white sugar
  • 4 large eggs
  • ¼ cup cocoa powder
  • ¾ cup all-purpose flour
  • ¼ teaspoon salt
  • 1 ½ cups peanut butter chips


  • Preheat the oven to 350F degrees.
  • Lina 9x13x2 inch pan with parchment paper, or line with aluminum foil and lightly grease. Ensure there's an overhang over the sides - this makes it easier to lift the brownies out.
  • Add the butter, chopped chocolate and peanut butter to a large microwave-safe bowl. Microwave for 1 minute on medium power (not high), remove from the microwave and stir. Repeat the process until almost melted, then stir until smooth.
  • In a separate bowl beat together the eggs and sugar until glossy and lighter in color (about 2 minutes).
  • Whisk the egg mixture into the melted peanut butter & chocolate mixture a little at a time.
  • Carefully fold the cocoa powder, flour & salt into the batter using a rubber spatula or wooden spoon. 
  • Fold in the peanut butter chips.
  • Pour the batter into the prepared pan and bake for 25-35 minutes - or until the top looks set and an inserted toothpick comes out clean or with a few damp crumbs. The middle of the pan shouldn't wobble if you nudge the pan.
  • Cool fully (about 3-4 hours) before cutting into squares with a thin, sharp knife. 


*Store brownies in an airtight container at room temperature for up to 4 days. Brownies freeze well, then thaw overnight in the fridge.
