How to Make Spider Web Halloween Brownies
Step 1: Prep Your Pan
Grease and line an 8×8-inch pan with parchment paper. Preheat your oven to 350°F (175°C).
Step 2: Mix the Batter
Melt the butter in a large bowl, then whisk in the sugar until glossy. Add eggs and vanilla, then stir in flour, cocoa powder, and salt until just combined. Fold in chocolate chips if using.
Step 3: Bake It Up
Pour the batter into your prepared pan and smooth the top. Bake for 28-32 minutes, or until a toothpick comes out with a few moist crumbs. Let them cool completely.
Step 4: Spin Your Web
Melt the marshmallows (or fluff) in the microwave in 10-second intervals until stretchy. Use a fork or your fingers to pull and stretch the marshmallow into thin strands, then drape them over the cooled brownies to form a web.
Step 5: Slice & Serve
Cut into squares and serve! Bonus points for topping with little candy spiders or Halloween sprinkles. Try pairing with Monster Brownies Halloween for the ultimate dessert spread.
Pro Tips
- Chill the brownies before webbing to help the marshmallow set faster.
- Don’t overbake—you want them fudgy, not cakey.
- Use gloves or greased hands to handle the marshmallow without sticking.
Flavor Variations
- Add a dash of cinnamon or chili powder for a Mexican hot chocolate twist.
- Swirl in some peanut butter before baking for a Reese’s-inspired treat.
- Use white chocolate chips instead for a fun flavor contrast.
Serving Suggestions
- Serve with a scoop of vanilla ice cream.
- Pair with spooky-themed drinks like Halloween punch.
- Wrap individually for party favors or trick-or-treat giveaways.
Make-Ahead and Storage
You can bake the brownies a day ahead and add the web right before serving. Store un-webbed brownies in an airtight container at room temp for up to 4 days.
Leftovers
Leftovers? Lucky you! Store them in a sealed container. If the marshmallow hardens, zap it in the microwave for 10 seconds to soften.
Freezing
Freeze the plain brownies (without the web) for up to 2 months. Thaw and decorate when ready to serve.
Reheating
Microwave individual brownies for 10-15 seconds to bring back the fudgy magic. Web will melt slightly, but still look cool!
FAQs
Can I use boxed brownie mix?
Absolutely! Just follow the package directions and add the webbing after they cool. This works well for Recetas Halloween if you’re short on time.
What if I don’t have marshmallows?
Marshmallow fluff works great, or you can use white chocolate drizzle for a different look.
Can I double the recipe?
Yes, use a 9×13-inch pan and adjust the baking time by 5-10 minutes.
Do these travel well?
They sure do! Just wait until the marshmallow web sets before packing them up.
