Halloween Brookies

Last year, my kids wanted a spooky and delicious Halloween party treat and demanded something more than my usual cookies. Thus, these Halloween Brookies—a magical mashup of brownies and crispy cornflakes—were born. They’re surprisingly easy to make and even easier to disappear from the dessert plate!

These brookies are a symphony of textures and flavors, with a rich, fudgy brownie base and a sweet, crunchy cornflake topping. The dark chocolate in the brownie layer provides a deep, intense flavor, while the milk chocolate in the cornflake layer adds a touch of sweetness and creaminess. It’s the best of both worlds – the chewiness of a brownie and the crisp of a treat – in a single bite.

Why You’ll Love It

These Halloween Brookies aren’t just delicious; they’re also incredibly fun! From the rich, fudgy brownies to the crunchy cornflake topping, every bite is a delight. Plus, they’re surprisingly simple to make, even if you’re not a baking expert. They’re sure to be a crowd-pleaser at your next Halloween gathering, or even just a fun, family-friendly baking project for a spooky movie night in.

Ingredient Lowdown

Here’s what you’ll need to conjure up these magical Halloween Brookies. Most of these items are pantry staples, but a quick trip to the store might be in order if you’re low on chocolate (never a bad thing!).

For the Brownies:

• 200g unsalted butter
• 300g caster sugar
• 200g dark chocolate
• 3 large eggs
• 100g plain flour
• 30g cocoa powder

For the Cornflakes Layer:

• 75g unsalted butter
• 300g milk chocolate
• 9 tablespoons golden syrup
• 150g cornflakes

Step-by-Step Instructions

Step 1: Prep the Brownie Base

Preheat your oven to 180°C (350°F) standard / 160°C (320°F) fan. Line a 9×9 inch square baking tray with parchment paper, leaving some overhang on the sides for easy removal later. This will save you a lot of scrubbing later!

Step 2: Melt the Chocolate and Butter

Break the dark chocolate into chunks and gently melt over a double boiler. Remove from heat once smooth and set aside to cool slightly. In a separate bowl, melt the butter in a microwave in 20-second bursts until smooth.

Step 3: Combine Wet Ingredients

Add the caster sugar to the melted butter and whisk (by hand is fine) for about a minute until light and fluffy. Then, add the eggs one at a time, whisking thoroughly after each addition. The mixture should be pale and smooth.

Step 4: Fold in Dry Ingredients

Gently fold in the melted dark chocolate, ensuring it’s not too hot. Sieve in the flour and cocoa powder, folding just until no streaks of flour remain. Don’t overmix!

Step 5: Bake the Brownies

Pour the brownie batter into the prepared baking tray and bake for 25-30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs. Don’t overbake, or you’ll lose that lovely fudgey texture.

Step 6: Cool Completely

Let the brownies cool fully on a wire rack before adding the cornflake layer. Patience is key here!

Step 7: Make the Cornflake Topping

While the brownies cool, prepare the cornflake topping. Melt the milk chocolate, golden syrup, and butter together in a double boiler or microwave until smooth and sticky.

Step 8: Combine with Cornflakes

Pour the melted chocolate mixture over the cornflakes and mix until they’re fully coated. This sticky, sweet coating is what makes these brookies so irresistible.

Step 9: Add the Topping

Spread the cornflake mixture evenly over the cooled brownies, pressing down gently to form a tight, even layer. This will create that satisfying crunch!

Step 10: Chill and Cut

Refrigerate the brookies for at least 30 minutes to allow the cornflake layer to set. Once chilled, cut into squares and serve.

Better-Than-Grandma Tips

• Don’t overbake the brownies! You want them to be fudgy, not cakey. A toothpick inserted into the center should come out with a few moist crumbs attached. Try our guide to baking perfect brownies to master your technique.
• For a cleaner cut, chill the brookies in the refrigerator for at least 30 minutes before slicing.
• If you’re short on time, you can melt the chocolate and butter in the microwave in 20-second bursts, stirring until smooth.

Switch-Ups & Swaps

• Nutty Brookies: Stir in a handful of chopped pecans, walnuts, or peanuts to the brownie batter or cornflake mixture.
• M&M Mayhem: Add a handful of Halloween-colored M&Ms to the cornflake topping for extra color and sweetness. You could also stir in some of our pumpkin spice cookies for seasonal fun!
• Drizzled Delight: Melt some white chocolate and drizzle it over the cooled cornflake topping for a decorative touch. You could also add some festive sprinkles.

How to Serve

These Halloween Brookies are fantastic on their own, but a few additions can truly transform them into a showstopping dessert. A scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of caramel sauce would be divine! For a spooky twist, add some Halloween sprinkles or gummy worms. Or serve with a side of warm pumpkin spice latte. The possibilities are endless!

That’s a Wrap

These Halloween Brookies are a spooky-sweet treat that everyone will adore. They’re perfect for Halloween parties, classroom celebrations, or a fun weekend baking project with the family. The combination of fudgy brownies and crunchy, chocolatey cornflakes is simply irresistible!
