Ingredients

2 cups white granulated sugar

3 large eggs

1 egg yolk

1/2 cup unsalted butter, melted

2 tsp pure vanilla extract

1/2 cup oil (canola or vegetable)

3/4 cup all-purpose flour

1 cup unsweetened cocoa powder (preferably Dutch-process)

1 1/2 tbsp cornstarch

1/2 tsp salt

1 cup semi-sweet chocolate chips

1 cup marshmallow creme

Instructions

  1. Preheat the oven to 325°F (163°C). Spray a 9×9-inch baking pan with nonstick baking spray. Line the bottom and two sides of the pan with parchment paper and spray again for easy removal.
  2. In a medium bowl, sift together the flour, cocoa powder, cornstarch, and salt. Set aside.
  3. Using a mixer with a whisk attachment, beat the sugar, eggs, and egg yolk on high speed for about 5 minutes, until the mixture becomes pale in color. While the mixture is beating, melt the butter in the microwave and set aside to cool.
  4. Add the oil, melted butter, and vanilla extract to the egg and sugar mixture. Mix on low speed until fully combined.
  5. Add the dry ingredients to the wet ingredients and mix on low speed until just combined. Fold in the chocolate chips with a rubber spatula.
  6. Pour the brownie batter into the prepared baking pan. Microwave the marshmallow fluff for 20-30 seconds to make it easier to dollop. Using a teaspoon, place small dollops of marshmallow fluff on top of the brownie batter. Lightly swirl the marshmallow fluff into the batter with a butter knife.
  7. Bake in the preheated oven for 45-55 minutes. The brownies are done when a toothpick inserted into the center comes out slightly wet (not runny). If a lot of batter comes out, bake for another 5 minutes and check again.
  8. Allow the brownies to cool completely on a cooling rack before cutting them into squares and serving.

Notes

  • If you prefer a nutty version, add a cup of chopped walnuts or pecans to the brownie batter.
  • For an added flavor twist, swirl in caramel sauce along with the marshmallow fluff.
  • For a more indulgent treat, drizzle chocolate ganache on top once the brownies are cooled.
