3 large eggs
03 -
1 egg yolk
04 -
½ cup unsalted butter, melted
05 -
2 teaspoon pure vanilla extract
06 -
½ cup oil (canola or vegetable)
07 -
¾ cup all-purpose flour
08 -
1 cup unsweetened cocoa powder (use Dutch process cocoa powder)

1 ½ tablespoon cornstarch

½ teaspoon salt
11 -
1 cup semi-sweet chocolate chips

1 cup marshmallow creme
# Instructions:
01 -
Preheat the oven to 325°F. Spray a 9X9-inch baking pan with baking nonstick spray. Line the bottom and 2 sides of the pan with parchment paper and spray again.
02 -
In a medium bowl, sift the flour, cocoa powder, and cornstarch together. Add in the salt and set aside.
03 -
Using a mixer with a whisk attachment, beat the sugar, eggs, and egg yolk on high speed for 5 minutes. It will become pale in color. While that mixes, melt the butter in the microwave and let it cool. Add the oil, melted butter, and vanilla and mix on low until combined.
04 -
Add in the dry ingredients and mix on low until just combined. Pour in the chocolate chips and use a rubber spatula to fold it in.
05 -
Pour the brownie batter into the pan. Melt the marshmallow fluff in the microwave for 20-30 seconds and mix. Use a 1 teaspoon to dollop the marshmallow fluff on top of the brownie batter. Use a butter knife to very light swirl the marshmallow fluff.
06 -
Bake for 45-55 minutes. It is done baking when you stick in a toothpick, and it is slightly wet. If a lot of batter comes out, then bake for another 5 minutes.
07 -
Cool on a cooling rack completely before cutting into them and serving.
# Notes:
01 -
These marshmallow brownies are super fudgy chocolate brownie with chocolate chips. It has marshmallow fluff swirled on top.
02 -
For the best texture, make sure not to overbake these brownies. They should still be slightly fudgy in the center when a toothpick is inserted.
03 -
Dutch process cocoa powder will give these brownies a deeper chocolate flavor and darker color.

Store in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
