  • Vanilla extract: adds warmth and depth to the chocolate flavor use pure vanilla if possible
  • Cocoa powder: provides the intense chocolate base opt for unsweetened and good quality
  • Allpurpose flour: gives the brownies their body and chew select finely milled for tender crumb

Combine Dry Ingredients:
In a separate bowl sift together cocoa powder flour salt and baking powder to avoid lumps then fold gently into the wet mixture until just combined overmixing can make the brownies tough
Fold in Chocolate Chips:
If using fold these in now to ensure they stay intact and distribute evenly throughout the batter

Cool Completely:

My favorite part of this recipe is the spiderweb design. It makes every brownie look unique and festive. I remember one Halloween when my kids proudly served these at school and everyone was impressed by how professional they looked.

Storage Tips

Store cooled brownies in an airtight container at room temperature for up to four days to maintain freshness. For longer storage wrap tightly in plastic wrap then foil and freeze for up to three months to enjoy later. To serve frozen brownies thaw in the refrigerator overnight to keep their fudgy texture.

Ingredient Substitutions

Butter can be swapped with coconut oil for a subtle tropical flavor or use vegan butter for dairy free versions. Use almond flour for gluten free adaptation but expect a slightly different crumb and texture. Dark cocoa powder can replace regular cocoa for a richer chocolate taste while Dutch processed cocoa will alter acidity and flavor slightly.

Serving Suggestions

Serve warm with a scoop of vanilla ice cream for a festive dessert. Pair with hot chocolate or pumpkin spice latte for a complete seasonal treat experience. Add a dollop of whipped cream topped with crushed candy corn for extra sweetness and crunch.
