Ingredients

  • 2 cups white granulated sugar
  • 3 large eggs
  • 1 egg yolk
  • 0.5 cup unsalted butter, melted
  • 2 tsp pure vanilla extract
  • 0.5 cup canola or vegetable oil
  • 0.75 cup all-purpose flour
  • 1 cup unsweetened Dutch process cocoa powder
  • 1.5 tbsp cornstarch
  • 0.5 tsp salt
  • 1 cup semi-sweet chocolate chips
  • 1 cup marshmallow crème

Instructions

  1. Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly grease it.
  2. In a large bowl, whisk together the sugar, eggs, and egg yolk until combined and slightly pale.
  3. Add the melted butter, vanilla extract, and oil. Whisk until smooth.
  4. In a separate bowl, sift together the flour, cocoa powder, cornstarch, and salt.
  5. Fold the dry ingredients into the wet mixture using a spatula, mixing just until combined.
  6. Fold in the chocolate chips.
  7. Pour half of the batter into the prepared pan.
  8. Drop spoonfuls of marshmallow crème over the batter.
  9. Spread the remaining batter on top and gently swirl the layers with a knife to create a marbled effect.
  10. Bake for 28–32 minutes, or until a toothpick inserted into the brownie (not marshmallow) comes out with a few moist crumbs.
  11. Let the brownies cool completely in the pan before slicing and serving.

Notes

  • For extra fudgy brownies, reduce flour to 0.5 cup and bake on the lower end of the time range.
  • You can use mini marshmallows instead of marshmallow crème for a chunkier texture.
  • Store at room temperature for up to 4 days, or refrigerate for a fudgier bite.
  • Freeze individually wrapped brownies for longer storage.
  • Reheat briefly in the microwave to restore gooey texture before serving.
