Directions

Step 1: Prep the Pan and Graham Crackers

1. Preheat your oven to 350°F (175°C). Line a 9×9-inch pan with parchment paper on all sides.

2. Arrange a single layer of graham crackers at the bottom of the prepared pan. You may need to cut some of the crackers to fit perfectly. Set aside.

Step 2: Prepare the Chocolate

1. In a medium bowl, combine chopped dark chocolate, cocoa powder, and espresso powder. Set aside.

Step 3: Brown the Butter

1. In a medium pan, heat the butter over medium heat. Stir occasionally. As the butter melts, the milk solids will separate and bubble. Once the fizzing slows down and the butter begins to foam, keep stirring. The milk solids will turn golden brown quickly. Once browned and the butter smells nutty, immediately remove it from heat.

Step 4: Melt the Chocolate

1. Pour the browned butter into the bowl of chocolate mixture to bloom the cocoa powder. Stir until the chocolate is fully melted and smooth. Let it cool for 10-15 minutes.

Step 5: Make the Brownie Batter

1. In a large mixing bowl, whisk together the eggs, granulated sugar, and brown sugar for about 2 minutes until well combined.

2. Slowly stream in the cooled chocolate mixture while continuing to whisk until fully incorporated.

3. Add the flour and fold until just combined. Be careful not to overmix.

Step 6: Assemble the Brownies

1. Pour the brownie batter on top of the graham cracker layer in the pan. Use a spatula to spread the batter into the corners of the pan, ensuring an even layer.

Step 7: Bake the Brownies

1. Bake for about 28-30 minutes or until the edges are set and a toothpick inserted in the middle comes out mostly clean with just a bit of wetness.

Step 8: Broil the Marshmallows

1. Once the brownies are baked, immediately move the oven rack to the top and place a layer of marshmallows on top of the brownies.

2. Turn on the broiler and broil the marshmallows for 2-3 minutes, or until they’re toasted to your liking. Be sure to watch them closely, as they can burn quickly!

Step 9: Cool and Slice

1. Let the brownies cool in the pan on a wire rack for at least 30 minutes before lifting them out using the parchment paper overhang.

2. Cool completely on the rack. If you’re in a hurry, you can refrigerate them for about an hour to speed up the cooling process.

3. Once cooled, slice the brownies carefully. Use a knife or offset spatula rubbed with a bit of cooking oil to prevent the marshmallows from sticking.

Variations

2. Peanut Butter S’mores Brownies: Swirl in some peanut butter into the brownie batter for a delicious twist.

3. Mini S’mores Brownies: Use a mini muffin tin to make smaller, bite-sized s’mores brownies for parties or snack-sized portions.

Storage/Reheating

• Room Temperature (1-2 days): Store the brownies in an airtight container at room temperature for up to 1-2 days.

• Refrigerator (up to 5 days): If you prefer a fudgier texture, store the brownies in the fridge. Allow them to come to room temperature before serving for the best texture.

• Freezer (up to 2 months): Wrap individual brownies in plastic wrap, then foil, or place in a freezer-safe bag. To serve, thaw them overnight in the fridge or at room temperature.

Reheating Tips:

• Toaster Oven or Oven (Best texture): Preheat to 150-160°C (300-320°F) and warm the brownies for 5-7 minutes. Cover loosely with foil to keep them soft.

• Microwave (Quick option): Wrap a slice in a damp paper towel and microwave for 10-15 seconds for a soft, warm texture.

FAQs

Can I use milk chocolate instead of dark chocolate?

Yes, you can use milk chocolate if you prefer a sweeter, less intense flavor, but it will change the taste slightly.

How do I prevent the marshmallows from burning?

Watch the marshmallows closely under the broiler. They can burn quickly, so don’t leave them unattended. Broil them for only 2-3 minutes and remove the pan as soon as they are golden and toasted.

Can I make these brownies without the espresso powder?

Yes, the espresso powder enhances the chocolate flavor, but if you don’t have it, you can simply omit it. The brownies will still be delicious!

How do I prevent the marshmallows from sticking when slicing?

Rub a bit of cooking oil on your knife or offset spatula before slicing the brownies to help prevent the marshmallows from sticking to the blade.

Can I use gluten-free flour in this recipe?

Yes, you can use a gluten-free all-purpose flour blend in place of regular all-purpose flour to make this recipe gluten-free. Be sure to check that the other ingredients, such as the graham crackers, are also gluten-free.

Can I make these brownies ahead of time?

Yes, you can prepare and bake these brownies in advance. Store them in an airtight container at room temperature for up to 2 days or refrigerate them for longer freshness.

Can I make these brownies without graham crackers?

While graham crackers are essential for that classic s’mores flavor, you can substitute them with crushed digestive biscuits or another type of cookie for a different base.

What can I substitute for the marshmallows?

If you don’t have marshmallows, you can use marshmallow fluff, though the texture and appearance will differ. Alternatively, you could try using meringue or whipped cream as a topping.

How do I know when the brownies are done?

Check for doneness by inserting a toothpick into the center of the brownies. It should come out mostly clean with just a little wetness remaining. The edges will be set and slightly pulling away from the pan.

How can I make these brownies more decadent?

For an extra indulgent treat, add a layer of chocolate ganache or drizzle some caramel sauce on top of the toasted marshmallows.
