These indulgent Chocolate Peanut Butter Skillet Brownies, made in mini cast-iron skillets, are seriously moist and decadent. The center is fudgy, and the edges are chewy — just the way we like our brownies around here!


Units Scale
  • 1 cup butter, melted
  • 1 cup sugar
  • 1 cup brown sugar
  • 3 large eggs, room temperature
  • 1/4 cup powdered peanut butter with dutch cocoa
  • 3/4 cup cocoa powder
  • 3/4 teaspoon salt
  • 2 teaspoons vanilla extract
  • 3/4 cup all-purpose flour
  • 2 tbsp peanut butter, melted


  1. Preheat oven to 350°F.
  2. In a large bowl, combine the butter, sugar, brown sugar, and vanilla. Blend until smooth using a hand blender (paid link). Slowly add in the eggs, one at a time. Blend until smooth.
  3. Fold in flour. Whisk (paid link) until combined. Fold in the powdered peanut butter with dutch cocoa, cocoa, and salt and whisk (paid link). The texture will be thick but smooth. Do not over mix. 
  4. Using butter or cooking spray, grease two 8-inch cast-iron skillets. Spread brownie batter evenly between two cast-iron skillets.
  5. Melt 2 tablespoons of peanut butter (you can microwave for 5-7 seconds). Add one tablespoon of peanut to the top of the brownie batter, creating a swirl using the flat edge of a butter knife.
  6. Bake your brownie at 350°F for 30 minutes. Remove from oven and allow to cool for 5 minutes. Serve with ice cream.
