Peanut Butter Swirl Fudge Brownies

You'll find it extremely difficult to only have one of these super-moist and fudgy brownies --- their fudge-like texture and gorgeous peanut-butter swirl make them positively irresistible!
Prep Time 10 minutes
Cook Time 20 minutes
Total Time 30 minutes
Servings 1 dozen brownies


  • 3/4 cup white whole wheat flour
  • 3/4 cup unsweetened cocoa powder
  • 1/4 teaspoon salt
  • 1 cup coconut sugar or brown sugar
  • 1/2 cup vegetable oil
  • 3 large eggs room temperature
  • 2 teaspoons vanilla extract
  • 1/2 cup creamy peanut butter


  • Preheat oven to 350F and lightly grease a 9x13 baking pan. Set aside.
  • In a medium bowl, combine flour, cocoa, and salt. In a large bowl, whisk coconut sugar, oil, eggs, and vanilla until smooth. Gently fold flour mixture into liquid, until just combined. (batter will be on the thicker side)
  • Spread batter evenly in prepared pan and then drop peanut butter by the tablespoon evenly over batter. Using a knife, gently cut through batter to create swirls. (do not stir too much, otherwise you'll lose the swirl effect)
  • Bake brownies at 350F 18-20 minutes, or until a toothpick comes out with moist crumbs still sticking to it. (brownies will be very soft---this is ok) Cool brownies on a wire cooling rack completely before cutting into squares.


Store brownies in an airtight container at room temperature up to 4 days.
