  • 1/4 cup butter, melted
  • 1/2 cup brown sugar + 2 tablespoons
  • 2 tablespoons white sugar
  • 1/2 cup creamy peanut butter
  • 1/2 teaspoon vanilla
  • 2 eggs
  • 2 tablespoons whole milk
  • 1 cup flour spooned and leveled
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1-2 tablespoons white sugar to top with

For the ganache:

  • 1/2 cup cream
  • 3/4 cup semi-sweet chocolate chips
  • dash salt
  • 1 tablespoon butter


  • Make the ganache first. In a bowl or tupperware, add the 1/2 cup cream. Microwave on high for about 1 to 1.5 minutes, or until the edges have started to bubble.
  • Immediately add the chocolate chips and let it sit for about 1 minute. Use a whisk to slowly combine the cream and chocolate. It should be smooth when you are done. Add a bit of salt and 1 tablespoon butter. Cover and put in the freezer for about an hour, or until it is cold enough to be hard to the touch.
  • Preheat your oven to 350 degrees F. Grease a 9x9 or 8x8 inch square pan, or line with foil (and grease) or parchment paper.
  • In a bowl, stir together melted butter, brown sugar and white sugar. Stir in the peanut butter, vanilla, eggs, and milk. Combine well.
  • In a separate bowl, whisk together flour, baking powder, and salt. Add to the wet ingredients and mix until just combined.
  • Spread the batter into the prepared pan. Take the ganache out of the freezer, and use a spoon to scoop it out and press into the batter. My scoops were probably 1-3 teaspoons each. It gets pretty melty pretty fast. By the end of adding mine it had pretty much returned to room temperature, and had swirled quite a bit. That's ok! Cover up the ganache with the batter as best you can.
  • Sprinkle 1-2 tablespoons white sugar over the top of the batter.
  • Bake at 350 for 28-29 minutes, or until the center has set and the top is golden. Let cool at least a few minutes before cutting.
