  • 6 tablespoons unsalted butter, softened (84 grams)
  • 3 1/2 ounces bittersweet or semisweet chocolate (100 grams)
  • 1 1/2 ounces unsweetened chocolate (42 grams)
  • 3/4 cup sugar (150 grams)
  • 3/4 teaspoons vanilla extract
  • 1/8 teaspoon salt
  • 2 large eggs
  • 1/2 cup all-purpose flour (65 grams)
  • 1/2 cup roasted salted peanuts coarsely chopped


  • 1/2 cup chunky peanut butter
  • 2 tablespoons unsalted butter, softened (28 grams)
  • 6 tablespoons powdered sugar
  • 1/16 teaspoon salt tiny, tiny pinch
  • 1/2 tablespoon whole milk
  • 1/2 teaspoon vanilla extract


  • 5 ounces bittersweet or semisweet chocolate, chopped (140 grams)
  • 2 tablespoons unsalted butter (28 grams)


  • Preheat oven to 325°F. Line an 8 inch baking pan with nonstick foil.
  • Place butter and both chocolates in a 3 quart saucepan. Set over medium-low heat and stir until melted and smooth. Whisk in sugar, vanilla and salt, then add eggs, one at a time, stirring just until mixed. Add flour and stir until blended, then stir in nuts.
  • Spread in prepared pan and bake until tester inserted into center comes out with moist crumbs attached, about 25 minutes. Place pan on rack and let cool.
  • Frosting: Using an electric mixer, beat the peanut butter and the 2 tablespoons of butter in medium bowl to blend. Beat in powdered sugar and salt, then milk and vanilla. Spread frosting over brownies and chill for about an hour to set frosting (this makes spreading the chocolate ganache easier).
  • Ganache: Place chocolate and the 2 tablespoons of butter in a small microwave-safe bowl or 2 cup Pyrex measuring cup. Heat on high 30 seconds. Stir and repeat until smooth. Drop ganache all over frosting; spread to cover. Chill until set, about 1 1/2 hours.
  • Using foil as aid, transfer brownie cake to work surface; cut into squares. Bring to room temperature; serve.
