S'mores Brownies

0 Preheat your oven to 350 degrees F and line a 9x9-inch pan with parchment paper, making sure the paper hangs over the sides for easy removal.
1 Place graham crackers on the bottom of the lined pan, breaking them if needed to fit.
2 In a medium-sized saucepan, melt the butter over medium heat. Once melted, remove from heat and stir in the sugars. Let the mixture cool for about 5 minutes.
3 Whisk the eggs and vanilla into the butter and sugar mixture. Add the cocoa powder and gently fold in the flour, baking powder, and salt until just combined
4 Pour the batter over the graham crackers in the pan and bake for approximately 30 minutes.
5 After 30 minutes, take the pan out of the oven and sprinkle the chopped chocolate over the top. Allow the chocolate to sit for a few minutes, then use a small offset spatula to spread it evenly over the brownies.
6 Arrange the marshmallows on top in rows and return the pan to the oven for an additional 5 minutes.
7 Once the marshmallows are slightly toasted, either use a kitchen torch to further toast the tops or place the pan on the top rack of your oven and broil for 15-30 seconds.
8 Let the brownies cool for about 20-30 minutes before cutting them into squares. Enjoy!
