Ingredients
  

  • Butter
  • Semi-sweet chocolate chips
  • Granulated sugar
  • Light brown sugar
  • Eggs
  • Vanilla extract
  • All-purpose flour
  • Unsweetened cocoa powder
  • Salt
  • Creamy peanut butter

Instructions
 

  • Preheat oven to 350°F. Spray an 8x8-inch baking dish with non-stick cooking spray and line with parchment paper.
  • Melt the butter in a saucepan over medium heat. Turn off heat and whisk in half of the chocolate chips until smooth. Let cool slightly.
  • Mix the wet ingredients. In a large bowl, stir together the melted chocolate mixture, granulated sugar, brown sugar, eggs, and vanilla extract.
  • Whisk the dry ingredients. In a separate bowl, combine flour, cocoa powder, and salt. Gradually fold into the wet mixture.
  • Add chocolate chips. Gently fold in the remaining chocolate chips.
  • Swirl in peanut butter. Pour the batter into the baking dish. Melt the peanut butter in the microwave for 20-30 seconds, then drizzle over the batter. Use a butter knife to swirl.
  • Bake for 40-50 minutes. Brownies are done when a toothpick inserted into the center comes out with a few moist crumbs.
  • Cool completely before slicing.

Notes

  • If using unsalted butter, increase salt to 1 teaspoon.
  • Store in an airtight container for up to 5 days or freeze for up to 3 months.
  • For extra fudgy brownies, remove from the oven as soon as the center is just set.
