Ingredients

Homemade Brownies:

1 ¼ cups granulated sugar
½ cup powdered sugar
¾ cups all-purpose flour
¾ cups unsweetened cocoa powder I've tested these with Hershey's & Target's Good & Gather brand
1 teaspoon kosher salt
½ teaspoon baking powder (not baking soda!)
1 tablespoon cornstarch
1 teaspoon espresso powder (totally optional!)
¾ cup semi-sweet chocolate chips or chunks
½ cup vegetable oil
¼ cups warm water
2 large eggs
1 teaspoon vanilla extract

Crust & Topping

16 graham cracker squares
½ cup semi-sweet chocolate chips or chunks, divided
18 large marshmallows, halved

Instructions

Whisk together 1 ¼ cups granulated sugar, ½ cup powdered sugar, ¾ cups all-purpose flour, ¾ cups unsweetened cocoa powder, 1 teaspoon kosher salt, ½ teaspoon baking powder (not baking soda!), 1 tablespoon cornstarch, and 1 teaspoon espresso powder (totally optional!) in a large bowl.
Add ½ cup vegetable oil, ¼ cups warm water, 2 large eggs, and 1 teaspoon vanilla extract into the bowl and mix with the whisk until just incorporated; batter will be thick.
Line a 9x9" light-colored aluminum metal pan with parchment paper, then cover the bottom with a layer of graham crackers (14 squares). Spoon batter into dollops on top of graham crackers and carefully spread to the edges.
Top with ¼ cup extra chocolate chips, then bake at 325℉ for 36-40 minutes, or until center 90% baked through. If you're using a 9x13 pan, bake for 24-26 minutes.
Do not turn off the oven yet!
Remove the brownies from the oven and immediately press the 18 large marshmallows, halved into the top, gently pressing them into the brownies (this will help so that they don't slide off later). Brownies will feel a little jiggly & raw. Sprinkle on remaining ¼ cup chocolate chips.
Place back in the oven for 6-8 minutes or until marshmallows are puffy and very lightly brown.
To finish them off & get the toasted color, broil on low until lightly toasted brown (this may only take 30 seconds!). You MUST watch the oven the entire time or your marshmallows will burn FAST - trust me!!!!
Remove from the oven and allow to full cool before cutting. While gooey treats can get messy to cut, wiping your knife off between each cut can help you achieve clean cuts.

Notes

Storage: Store in an airtight container for 3-4 days. The brownies get even fudgier on Day 2!
Freezing: I don't recommend freezing these after putting on the marshmallows or they'll become sticky.
