For decorating:

• Candy eyes
• Halloween sprinkles (orange, black, green)

How to Make Halloween Brownies Step-by-Step

How to Make Halloween Brownies That Wow

1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish or line it with parchment paper.
2. Melt the butter in a large microwave-safe bowl. Stir in sugar until glossy and smooth.
3. Add eggs and vanilla and beat until fully combined.
4. Sift in the cocoa powder, flour, salt, and baking powder. Stir until a thick batter forms.
5. Pour the batter into your prepared pan and smooth the top evenly.
6. Bake for 30–35 minutes, or until the center is set and a toothpick comes out with moist crumbs.
7. Let cool completely before decorating (this part is key!).

Decorate:

• Spiderwebs: Use melted white chocolate or icing to draw circles, then drag a toothpick through the lines.
• Graveyard brownies: Add cookie “tombstones” and crushed Oreo “dirt.”
• Mummies: Pipe white chocolate “bandages” and press in candy eyes.
• Monster faces: Use food coloring, candies, and sprinkles to make fun characters.

• For cleaner slices, chill brownies slightly before cutting.
• Use a plastic knife or hot blade for the cleanest cuts.

• Try peanut butter cups, candy corn, or marshmallows on top before baking!
