Simple Way to Prepare Spider Web Brownies

What Are the Best Tips for Spider Web Brownies

• Watch sugar closely while melting – it can burn quickly, turning your sweet treat bitter in seconds.
• Melt chocolate and butter gently over water, stirring carefully to keep the mixture smooth and prevent burning.
• Fold flour into your chocolate mixture with a light hand to keep brownies tender and prevent tough, dense results.
• Use a skewer to create delicate marble patterns, dragging it gently through batter for a beautiful spider web effect.
• Stretch marshmallow strands quickly and delicately over cooled brownies, working fast before the marshmallow hardens.

Flavorful Options For Spider Web Brownies

• Gluten-Free Spider Web Brownies: Replace wheat flour with almond flour or a gluten-free blend, keeping the same measurement to ensure your brownies stay just as rich and decadent.
• Vegan Chocolate Caramel Version: Swap butter for coconut oil, use plant-based chocolate, replace eggs with mashed banana or flax eggs, and create caramel using coconut milk and coconut sugar for a dairy-free treat.
• Nut-Free Halloween Brownies: Substitute almond flour with oat flour or rice flour, ensuring your chocolate treat is safe for friends with nut allergies while keeping the same delightful texture.
• Low-Sugar Spider Web Treat: Use monk fruit sweetener instead of sugar, reduce overall sweetness, and opt for dark chocolate with higher cocoa content to maintain the rich flavor profile for a more health-conscious dessert.

Creative Serving Ideas For Spider Web Brownies

• Slice and Serve Generously: Cut these brownies into neat squares when totally cool, giving each person a thick, decadent piece that shows off the caramel swirl.

Instructions

1. Melt 150g dark chocolate and 150g unsalted butter together in a double boiler until smooth and glossy. Remove from heat and let cool slightly.
2. Whisk 2 large room temperature eggs with 220g white caster sugar until the mixture becomes pale and increases in volume, about 3-4 minutes.
3. Gently fold the melted chocolate mixture into the egg mixture until completely incorporated.
4. Sift 150g self-raising flour into the batter and fold carefully to maintain airiness, ensuring no flour streaks remain.
5. Preheat your oven to 350°F and line a 20×20 cm baking tin with parchment paper, allowing slight overhang for easy removal.
6. Pour half the brownie batter into the prepared tin, creating an even base layer.
7. For caramel, heat 100g granulated sugar in a saucepan over medium-low heat until it turns amber, approximately 5-7 minutes.
8. Whisk 40g butter into the caramel until fully combined, then slowly add 100g cream, stirring constantly.
9. Sprinkle ½ teaspoon salt into the caramel and mix. Let cool for 10 minutes.
10. Drizzle the caramel over the first brownie layer, then cover with remaining batter.
11. Use a skewer to create swirling marble patterns across the surface.
12. Bake at 350°F for 22-25 minutes, checking for a set top but slightly fudgy center.
13. Allow brownies to cool completely in the tin, about 1 hour.
14. Melt 100g marshmallows in 15-second microwave bursts, stirring between each.
15. Stretch marshmallow into thin strands, draping them across the brownies to create a web effect.
16. Decorate with edible eyes for a spooky finishing touch.

Notes

• Check caramel consistency by cooling a small amount on a cold plate, which should form a soft but not runny texture.
• Ensure chocolate and butter melt together gently to prevent burning, using a double boiler or heat-safe bowl over simmering water.
• Work quickly when creating marshmallow web, as the mixture hardens fast and becomes difficult to stretch into delicate strands.
• For gluten-free version, replace wheat flour with almond or gluten-free blend, which maintains similar rich brownie texture.
