Print Recipe


  • 1 cup all-purpose flour
  • ½ teaspoon table salt
  • 1/4 teaspoon coarse sea salt
  • ¼ teaspoon baking soda
  • ½ cup 1 stick unsalted butter
  • ½ cup dark brown sugar
  • ¾ cup light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ cup milk chocolate chips divided
  • ½ cup peanut butter chips divided
  • ½ cup salted honey roasted peanuts divided


  • Adjust oven rack to middle positions and heat oven to 350°F. Spray an 8x8-inch square baking pan with nonstick cooking spray.
  • In a medium mixing bowl, whisk together flour, salts and baking soda.
  • In a heavy, large saucepan set over low heat, melt butter. Remove from heat and add brown sugar.
  • Cool mixture for 2 minutes and add eggs and vanilla; whisk until smooth.
  • Use a rubber spatula to stir in the flour mixture and half of the chocolate and the peanut butter chips. Also, add half of the peanuts, if using.
  • Spread batter evenly in the prepared pan and sprinkle with the remaining chips and peanuts.
  • Bake at 350°F for 25-35 minutes or until a toothpick inserted in the center comes out clean – the edges should just begin to pull away from the sides of the pan.
  • Transfer the Blondies to a cooling rack and leave in the pan to cool completely.
  • The Blondies can be made up to 2 days ahead. To store, cover tightly and store at room temperature.
  • The Blondies freeze beautifully.
  • Enjoy!
