For the richest chocolate flavor, use unsweetened Dutch-process cocoa powder. It gives a deep, intense chocolate base that plays beautifully with the sweetness of the toppings. However, natural cocoa powder works too—your brownies will still be deliciously moist and chocolatey!

How To Make the Halloween Brownies

Step 1: Prep the Pan

Preheat the oven to 350°F (175°C) and line an 8×8-inch square baking pan with parchment paper, leaving an overhang for easy removal. Lightly grease the paper.

Step 2: Make the Brownie Batter

In a large microwave-safe bowl, melt 1/2 cup (1 stick) of butter. Stir in 1 cup granulated sugar and 1/4 cup brown sugar until combined. Mix in 2 large eggs and 1 teaspoon vanilla extract until smooth.

Step 3: Add the Dry Ingredients

Sift in 1/2 cup unsweetened cocoa powder, 1/2 cup all-purpose flour, and 1/4 teaspoon salt. Stir just until no dry streaks remain. Do not overmix.

Step 4: Bake the Brownies

Pour the batter into the prepared pan and smooth the top. Bake for 25-28 minutes, or until a toothpick inserted comes out with moist crumbs (not wet batter). Let them cool completely in the pan.

Step 5: Decorate with Halloween Toppings

Melt 1/3 cup semi-sweet chocolate chips and drizzle it over the cooled brownies. Sprinkle with 1/2 cup Halloween candy-coated chocolates and optional orange/purple sugar sprinkles. Lightly press toppings into the surface so they stick.

Step 6: Slice and Serve

Once the chocolate drizzle has set, lift the brownies out using the parchment paper. Slice into 9 or 12 pieces, depending on how generous you want to be!

How to Store Halloween Brownies

Store these brownies in an airtight container at room temperature for up to 4 days. If your kitchen runs warm, you can refrigerate them for up to a week—just let them come to room temp before serving for that soft, fudgy bite. They also freeze beautifully: wrap each brownie individually in plastic, then foil, and freeze for up to 2 months.
