How to Make S’mores Brownies
Making S’mores Brownies takes a bit of effort, but the result is well worth it. Here’s a simple breakdown of the process. We’ll divide this into two days to make it easier.
DAY 1
Making the Biscuit Base
- Prepare the Biscuits: Start by crushing the biscuits into fine crumbs. You can use a food processor or place them in a zip-lock bag and crush them with a rolling pin.
- Mix with Butter: In a bowl, combine the crumbs and melted unsalted butter. Stir until all the crumbs are coated with butter.
- Press into a Pan: Line a baking dish with parchment paper. Pour the crumb mixture into the dish and press it down firmly to create a solid base.
Making the Brownie Layer
- Melt the Chocolate: In a heatproof bowl, melt the dark chocolate and the additional unsalted butter together. You can do this over a pot of simmering water or use a microwave in short bursts.
- Mix Wet Ingredients: In another bowl, beat the eggs, granulated sugar, and soft light brown sugar until smooth. Add the melted chocolate mixture and mix well.
- Add Dry Ingredients: Sift together the plain flour, cocoa powder, and salt. Gradually fold this dry mixture into the wet mixture until just combined.
- Pour Over Biscuit Base: Pour the brownie mixture over the biscuit base in the pan and spread it evenly.
Making the Marshmallow Layer
- Prepare Gelatin: In a small bowl, combine the powdered gelatin with 60 ml of water. Let it sit for a few minutes to bloom.
- Cook Marshmallow Mixture: In a saucepan, combine 200 g granulated sugar, 60 ml water, 1/8 teaspoon salt, and golden syrup. Heat over medium heat until the sugar dissolves.
- Add Gelatin: Once the sugar mixture is boiling, remove from heat and stir in the bloomed gelatin and vanilla bean paste until fully dissolved.
- Whip the Marshmallow Mixture: Transfer the mixture to a mixing bowl and beat it with an electric mixer for about 10 minutes, or until it becomes thick and fluffy. Spread this marshmallow layer over the brownie layer.
- Let it Set Overnight: Allow the dessert to cool and then cover it. Place it in the fridge overnight so the marshmallow sets properly.
DAY 2
After letting it set overnight, your S’mores Brownies are now ready to be sliced and served!
Best Ways to Serve S’mores Brownies
S’mores Brownies are best enjoyed at room temperature or slightly warmed up. You can sprinkle some crushed biscuits on top for extra crunch or drizzle some chocolate sauce for added sweetness. Pair with a cup of coffee or a glass of milk for a comforting treat. These brownies are also great for sharing, so cut them into small squares and serve them on a platter at your next gathering.
How to Store S’mores Brownies
To store your S’mores Brownies, keep them in an airtight container. They can last in the refrigerator for up to one week. If you want to keep them longer, you can freeze individual pieces. Wrap them tightly in plastic wrap, then place them in a freezer bag. They can be frozen for up to three months. Thaw in the fridge overnight before enjoying.
Easy Tips to Make S’mores Brownies
- Don’t Rush the Cooling: Make sure to cool the brownie and marshmallow layers completely before cutting. This helps them hold their shape.
- Customize Your Chocolates: You can mix different types of chocolate (milk, white, dark) for a variety of flavors.
- Use Cooking Spray: Lightly grease the baking pan with cooking spray or line it with parchment paper for easy removal.
- Top with Extra Treats: Feel free to top the brownies with chocolate chips, crushed nuts, or extra biscuits for added texture and flavor.
Try These Variations of S’mores Brownies
- Nutty Version: Add some chopped nuts to the brownie batter for an extra crunch.
- Fruit Twist: Incorporate diced strawberries or raspberries into the marshmallow layer for a fruity surprise.
- Spicy Kick: Add a pinch of cayenne pepper or cinnamon in the brownie mix for a warm spice flavor.
Common Questions About S’mores Brownies
How Can I Cut the Brownies Cleanly?
Use a sharp knife and wipe it clean between cuts. This helps to keep the edges neat and prevents the marshmallow from sticking to the knife.
Can I Use Store-bought Marshmallows Instead of Making My Own?
Yes, you can! If you prefer a shortcut, just top the brownie layer with regular marshmallows and toast them under the broiler for a few minutes until they’re golden brown.
What if I Don’t Have Gelatin?
If you’re not using gelatin, you can skip the marshmallow layer or look for a vegetarian alternative like agar-agar as a thickening agent.
