Bonfire Brownies

1. Preheat the oven to 350ºF. Line a 9-inch square baking dish with parchment paper or aluminum foil, letting some hang over the edges of the pan.2. Arrange the graham crackers in a single layer on the bottom of the prepared baking dish, being sure the entire bottom is covered—you may need to break some to fit.3. Put the butter and milk chocolate in a medium microwave-safe bowl. Microwave in 30-second intervals, stirring in between, until melted and smooth. Add the sugar and whisk until completely combined. Add the vanilla, coffee, Kahlúa (if using), and eggs and whisk until smooth. Stir in the cocoa powder, flour, and salt until smooth and just combined. Try not to overmix the batter; it will be thick. Fold in the almonds. Pour the batter over the graham crackers in the baking dish. Gently press the pretzels on top. 4. Bake for 25 to 30 minutes, until the brownies are set on top. Remove from the oven and immediately add the chocolate bar pieces to the top of the brownies—the chocolate will melt over the brownies. Add the marshmallows evenly over the chocolate and then return the brownies to the oven. After 5 minutes, turn on the broiler. Wearing oven mitts, position a rack in the top third of the oven. Broil the brownies for 15 to 30 seconds, or until the tops of the marshmallow are just golden—watch closely, as they burn fast. Remove from the oven and let the brownies cool in the pan for about 30 minutes. 5. Lift the brownie block out of the pan using the overhanging parchment paper. Cut into squares.
