Last October, our little town hosted a neighborhood Halloween walk that filled the streets with laughter, candlelit pumpkins, and the scent of cinnamon from every porch. My husband and I set up a table with steaming cider for the kids and a tray of brownies for the adults. But not just any brownies—these were bright swirls of green and purple, looking as though they’d been stirred up in a cauldron.
The first batch disappeared before I could even cut neat squares, and one of my grandkids whispered, “Grandma, it looks like magic got baked inside!” That was enough to make me smile and tuck the recipe into my collection of family favorites.
I’ve always believed that Halloween is less about fright and more about fun. Food becomes part of the costume, the laughter, the mischief. These Witch’s Brew Brownies capture that spirit perfectly. They’re rich and fudgy, but playful too—each bite feels like a treat straight from a witch’s kitchen.
The marbled colors delight little ones, while the deep chocolate satisfies adults. When I pull them from the oven, my kitchen fills with the smell of melted cocoa and sugar, and I know they’ll be the centerpiece of any gathering.
Short Description

Key Ingredients
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- ½ teaspoon salt
- ½ teaspoon baking powder
- ½ cup dark chocolate chips
- Green food coloring
- Purple food coloring
- Halloween-themed sprinkles (optional)
Tools Needed
- 9×13-inch baking pan
- Parchment paper
- Two mixing bowls
- Whisk and spatula
- Toothpick or butter knife (for swirling)
- Measuring cups and spoons
Cooking Instructions
Step 1: Preheat and Prepare Pan
Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, letting the edges hang slightly for easy removal later.
Step 2: Mix Wet Ingredients
In a large bowl, combine melted butter and sugar. Beat until smooth. Add eggs one at a time, whisking after each addition. Stir in vanilla extract.
Step 3: Combine Dry Ingredients
In another bowl, sift together flour, cocoa powder, salt, and baking powder. Slowly fold the dry mixture into the wet mixture until just combined. Be careful not to overmix.
Step 4: Add Chocolate Chips
Fold in the dark chocolate chips for extra richness.
Step 5: Color and Swirl Batter
Divide the batter into two bowls. Add green food coloring to one portion and purple to the other. Pour both batters into the prepared pan in alternating scoops. Drag a toothpick or knife through the batter to create a marbled effect.
Step 6: Bake
Place the pan in the oven and bake for 25–30 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.
Step 7: Cool and Decorate
Allow brownies to cool completely in the pan. Cut into squares and, if desired, add Halloween sprinkles for a festive finish.
Troubleshooting tip: If the brownies sink in the middle, they may have been underbaked. Pop them back in for a few more minutes until set.

FAQs
1. Can I use boxed brownie mix instead of homemade?
Yes, but the texture and richness may differ slightly. Add the colors and swirl as directed.

You can skip it, but the brownies won’t have the same spooky look. Natural food dyes also work.
4. Can I make these gluten-free?
Yes, replace the flour with a 1:1 gluten-free baking mix.
5. How do I cut neat squares?
Use a sharp knife dipped in hot water, wiping between cuts for clean edges.

Chill the brownies before slicing to avoid crumbs.
For a thicker brownie, bake in a smaller pan and increase time slightly.
Add a teaspoon of espresso powder to deepen the chocolate taste.
Sprinkle crushed Oreos or candy eyes on top before baking for extra fun.
