All you need for this recipe and more...


  • ¾ cup (1 1/2 sticks) salted butter, melted
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 cups granulated sugar
  • 3 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup all-purpose flour
  • ½ cup creamy peanut butter
  • Frosting:
  • 3 Tablespoons salted butter
  • ¼ cup whole milk
  • 3 cups powdered sugar
  • ¼ cup strawberry preserves


  1. Preheat oven to 350. Butter and flour a 9-inch square cake pan and set aside.
  2. In a large bowl, whisk together the cocoa and melted butter. Stir in sugar until combined. Stir in eggs, one at a time, mixing well after each. Stir in vanilla. Fold in flour JUST until you no longer see flour streaks in the batter. Spread in prepared pan.
  3. In a small microwave-safe bowl, heat peanut butter for 10 seconds. Stir. Spoon peanut butter over brownies. Using a knife, swirl the peanut butter into the brownie batter.
  4. Bake brownies for 15 – 20 minutes until a toothpick inserted in the center comes out with fudgy crumbs (but no raw batter). Set aside.
  5. Prepare strawberry jelly frosting: In a small saucepan, melt butter over medium heat. Whisk in milk, powdered sugar, and jelly. Continue to whisk over medium heat until mixture comes to a boil. Boil for one minute, then remove from heat and pour over brownies.
  6. Let brownies cool to room temperature, then refrigerate until chilled.
