Instructions
- Position a rack in the center of your oven. Preheat the oven to 350°F (180℃). Lightly coat a 9 by 13 baking pan with cooking spray or line with parchment paper.
- Whisk together the flour, graham cracker crumbs, baking powder and salt into a bowl. Set aside.
- In a second mixing bowl, whisk together melted butter, brown sugar, eggs, and vanilla.
- Add dry ingredients and mix until just combined, 5 to 10 seconds. Spread batter into prepared pan.
- Bake for about 22-25 minutes, or until the top is set and golden brown. Bars may appear to be not done, but they will set up as they cool.
- Remove the pan from the oven. Layer the top with the chocolate bars. Top with marshmallows.
- Turn the oven to broil and return the bars to the oven for 1 to 2 minutes or until the marshmallows are lightly toasted. Keep a close eye on them so they don't burn! Set the pan on a wire rack and cool completely before cutting into bars.
