I took a (very official) Facebook poll to see which you prefer – brownie or blondie. I think brownie came out slightly ahead but those of you that picked blondies should give these a shot.

Even if you’re usually a brownie lover, like me, try these.

They’re soft and chewy (there’s a lot of brown sugar in them) and are perfect with a glass of milk. (Plus, I threw some chocolate chips in the batter for good measure.)

  • ½ cup salted butter at room temperature
  • 2 cups light brown sugar
  • ½ cup creamy peanut butter
  • 2 large eggs
  • 1 Tablespoon vanilla
  • 2 ⅛ cups flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup chocolate chips I always use Ghirardelli baking chips
  • ½ cup Reese’s Pieces


  • Preheat your oven to 350 degrees.
  • Lightly spray a 9 x 13 pan with non-stick spray (I like to use coconut oil spray) and set aside.
  • In a large bowl, add the butter and brown sugar. Use a hand mixer to mix until fully combined.
  • Add in the peanut butter and stir with a spatula to combine.
  • Add in the eggs and vanilla and stir to fully combine.
  • In another medium bowl, add the flour, baking powder, and salt and toss to combine.
  • Stir the dry ingredients into the wet ingredients until fully combined.
  • Pour in the chocolate chips and stir to evenly distribute into the batter.
  • Push the batter evenly into the prepared pan using a spatula (or your fingers).
  • Press the Reese’s Pieces into the top.
  • Bake for 30 minutes or until a toothpick inserted into the center comes out clean.
  • Let cool on a cooling rack before slicing.
