  • 1 stick 4 ounces unsalted butter
  • 1 1/2 cups packed light brown sugar
  • 2 teaspoons vanilla extract
  • 1 teaspoon mild molasses
  • 2 large eggs room temperature
  • 1/2 cup 5 ounces weight creamy or crunchy peanut butter
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt plus an extra pinch
  • 1 1/2 cups 6.8 ounces all-purpose flour
  • 1 cup Reese’s Minis
  • 1 cup Hershey’s milk chocolate melting chips
  • 1/2 cup Reese’s Pieces


  • Preheat oven to 350°F Line a 9x13 inch metal pan with nonstick foil. For a half batch, use an 8 inch square metal pan.
  • In a small saucepan or microwave-safe bowl, melt the butter. Pour the hot butter into a large mixing bowl and add the brown sugar. Stir well and let cool slightly to that the brown sugar melts a little bit.
  • Whisk in the vanilla, molasses, room temperature eggs, and peanut butter.
  • Add the baking powder and salt and whisk until blended, then gently whisk in the flour.Stir in melting chips, Reese’s Minis and Reese's Pieces (if using).
  • Spread in the pan and bake for 25 to 30 minutes or until wooden pick inserted in center comes out clean


-- For a half batch, use half the ingredients and bake in an 8 inch square pan.
-- If eggs are room temperature, you won't have to beat (whisk) them quite as hard to mix them with the other ingredients and will probably end up whisking less air into the batter. In my experience, whisking or stirring ingredients rather than beating them usually makes a denser, less cakey, bar. these are not cakey at all.
