Letโs get baking!

๐ Ingredients Youโll Need
For the brownies:
โข 1 box of brownie mix (or your favorite homemade recipe)
โข Ingredients listed on the box (usually eggs, oil, and water)
โข Optional: 1 teaspoon vanilla extract for extra flavor
For the spiderweb topping:
โข 2 cups mini marshmallows (regular size works too)
โข 1โ2 teaspoons water (optional, helps melting)
โข Nonstick cooking spray or a little oil (to keep your hands from sticking)
For the decorations:
โข Candy spiders (I found mine at Walmart, but you can also use plastic spider rings, gummy spiders, or even pipe spiders out of black icing)
๐ท๏ธ Step-by-Step Tutorial
Step 1: Bake Your Brownies
1. Preheat your oven according to the brownie mix directions.
2. Prepare the brownie batter as instructed. If youโre making homemade, mix your wet and dry ingredients until smooth and glossy.
3. Pour the batter into a greased or parchment-lined 9×13-inch baking pan.
4. Bake until set โ usually 25โ35 minutes, depending on your recipe and oven.
5. Let the brownies cool completely before decorating (this is crucial so the marshmallows donโt melt into a sticky puddle).
โจ Pro Tip: For neat slices, line your pan with parchment paper, leaving some hanging over the edges. Once cooled, you can lift the entire brownie slab out to decorate and cut.
Step 2: Make the Marshmallow Webs
1. Place your marshmallows in a microwave-safe bowl.
2. Microwave in 20โ30 second increments, stirring in between, until melted and smooth. (It should look glossy and stretchy.)
3. Lightly oil or spray your fingertips to prevent sticking.
4. Scoop up some melted marshmallow with your hands, then stretch and pull it apart into thin, stringy strands.
5. Carefully drape and stretch these strands across the cooled brownies in all directions to mimic a spiderweb pattern.
โจ This is the fun (and messy!) part. Kids especially love helping with this step โ it feels like edible arts and crafts.
Step 3: Add the Spiders
1. Once the marshmallow web is set, place your candy spiders on top.
2. Scatter them randomly, or group a few in โclustersโ for a creepy-crawly effect.
3. Press them lightly so they stick into the marshmallow without sinking.

Step 4: Slice & Serve
1. Use a sharp knife, greased with a little oil, to slice the brownies cleanly through the marshmallow topping.
