Small Batch Peanut Butter Brownie Skillet

5 from 3 reviews

Rich, fudgy brownies and peanut butter chips are a match your tastebuds won’t be able to resist! This decadent one-bowl recipe is ready in under 20 minutes and it’s made in a mini cast-iron skillet, the perfect serving size for two (but you don’t have to share!).


  • 1 egg (60g)
  • 7 TBSP (110g) granulated sugar 
  • 3 TBSP (35g) neutral oil (like vegetable or canola)
  • 6 TBSP (55g) all-purpose flour
  • 3 TBSP (20g) cocoa powder 
  • ¼ tsp fine salt
  • ½ cup (80g) peanut butter chips
  • Optional: 2 TBSP (30g) semi-sweet chocolate chips


  1. Preheat the oven to 350°F. Lightly grease an 8-inch cast-iron skillet.
  2. In a mixing bowl, whisk together the egg and sugar for 1-2 minutes until light and pale yellow. Add in oil and whisk to combine.
  3. Gently fold in the remaining ingredients just until combined. The batter will be thick. Reserve a few chips to place on the top of the batter if desired. Spread evenly in the cast-iron skillet.
  4. Bake for 15-17 minutes until edges are set; the center will still be gooey. Let cool for 2-3 minutes then top with ice cream and serve (right out of the cast-iron) or let cool completely before slicing to serve.
