Ingredients

Servings

For the Brownies

  • 6 ounces semi-sweet baking chocolate or dark chocolate chopped coarsely (such as Baker’s brand semi-sweet chocolate, or I use a 72% Pound Plus Bar from Trader Joe’s)
  • ¾ cup unsalted butter 1 1/2 sticks
  • 1 ½ cups granulated sugar
  • ½ cup light brown sugar packed
  • 2 tablespoons espresso or brewed coffee any temperature; optional but recommended
  • 1 ½ teaspoons vanilla extract
  • 3 large eggs
  • 1 cup all-purpose flour
  • pinch salt optional and to taste

For the Peanut Butter Buttercream

  • 1 cup creamy peanut butter I recommend Jif or Skippy, not a fancy high-end or natural peanut butter because they separate and your frosting results could be compromised
  • ½ cup unsalted butter 1 stick, softened
  • 2 teaspoons vanilla extract
  • 1 ½ to 2 cups confectioners’ sugar
  • pinch salt optional and to taste
  • Sprinkles optional

Instructions

For the Brownies

  1. Preheat oven to 350F. Line a 9-by-9-inch pan with aluminum foil and spray with cooking spray; set aside.
  2. In a large microwave-safe bowl, add the butter and chocolate and heat on high power to melt, about 60 to 90 seconds. Stop to sir, and heat in 10-second bursts until the mixture has melted and can be stirred smooth.
  3. Add the sugars and whisk to combine; batter will seem granular.
  4. Add the optional coffee, vanilla, and whisk to incorporate.
  5. Add the eggs and whisk vigorously to incorporate. Stir in the flour, optional salt, stirring until just incorporated; don’t overmix.
  6. Pour into prepared pan. Bake for about 25 to 35 minutes, or until center is just set and not jiggly, edges have pulled away slightly from sides of pan, and a toothpick inserted in the center comes out mostly clean. My perfect baking time is about 28 minutes based on my oven and climate (dry). Keep these gooey and don’t overbake; brownies will continue to firm up as they cool.
  7. Allow to cool for at least 1 hour before frosting them or before slicing and serving.

For the Peanut Butter Buttercream

  1. Combine peanut butter and butter in a large mixing bowl and beat on medium-high speed to soften and blend, about 2 minutes.
  2. Add the vanilla, 1 1/2 cups confectioners’ sugar, optional salt (cuts some of the sweetness), and beat to incorporate and until frosting is smooth and fluffy.
  3. Add more confectioners’ sugar based on desired thickness (I use 2 cups so frosting is thicker and more paste-like).
  4. Frost the brownies, add optional sprinkles, slice, and serve.

Notes

  • Brownies may be stored in an airtight container at room temperature for a few hours (or longer depending on your comfort level with buttercream frosting at room temp), but I prefer them chilled and store them in the refrigerator.
  • Brownies will keep for up to 5 days in an airtight container in the refrigerator. I’ve successfully made them, frosted them, froze them, and thawed them with success, up to 3 months later.
