Ingredients You’ll Need

For this Make-Your-Own Halloween Brownies Recipe, I’ve kept the ingredients simple so you can focus on what really makes this recipe shine—the decorations! Everything pairs perfectly to give you that rich brownie flavor with vivid, fun frosting colors.

• Betty Crocker™ Fudge Brownie Mix: This mix gives you that classic fudgy texture without needing extra effort—my go-to for quick brownies.
• Water, vegetable oil, and eggs: Standard basics for the brownie mix—pro tip, room temperature eggs help the batter blend better for a smoother result.
• Betty Crocker™ Rich & Creamy Vanilla Frosting: The blank canvas for all your spooky designs; it spreads easily and tastes great with chocolate.
• Betty Crocker™ Neon Gel Food Colors: These gels create vibrant hues, perfect for Halloween’s signature bright orange, green, purple, or whatever you dream up.
• Betty Crocker™ Black Writing Gel or Cookie Icing: Fantastic for drawing faces, spider webs, or writing fun Halloween messages.
• Assorted candies and snacks: Think candy corn, spooky sprinkles, Bugles™, candy eyeballs, mini chocolate candies, and black licorice—these add texture and personality that your guests will adore.

Variations

I love how this Make-Your-Own Halloween Brownies Recipe lets you play around and make it your own. Over the years, I’ve tried a bunch of tweaks, and I encourage you to experiment too—because that’s what makes this recipe super fun and personalized!

• Gluten-Free Variation: Whenever I’ve had guests with gluten sensitivities, I swap the brownie mix for a gluten-free version, and it works just as well!
• Vegan Version: Try using a dairy-free frosting and substitute eggs with flax eggs for a vegan twist—this requires a bit more hands-on effort but is totally worth it.
• Spicy Pumpkin Brownies: For a seasonal change, I mix a little cinnamon and pumpkin pie spice into the brownie batter before baking—it’s a cozy Halloween treat.
• Extra-Decadent: Add chopped nuts or chocolate chips into the batter for some irresistible texture.

How to Make Make-Your-Own Halloween Brownies Recipe

Step 1: Bake the Perfect Brownie Base

Start by preheating your oven to 350°F (I always set my timer here to avoid distractions). Grease the bottom of an 8- or 9-inch square pan with shortening or cooking spray—you want it to be well-coated so your brownies slide out easily later. Follow the instructions on the brownie mix box: combine the mix with the required water, vegetable oil, and eggs. Stir until just combined; overmixing can toughen brownies, so gentle is better here. Pour the batter into the pan and bake according to the box directions. When the brownies come out, let them cool completely. I usually give them about an hour and a half to cool—this step is key so your frosting doesn’t melt during decorating. Once cooled, cut them into 6 rectangles, which will be your decorating canvas.

Step 2: Customize Your Frosting Colors

Divide the vanilla frosting into small bowls—one for each color you want to create. I like to use gel food coloring (the neon ones are so bright and festive!). Add a drop or two until you get the shade you’re aiming for, then stir well. This part always feels like a mini science experiment, and the kids get a real kick out of mixing colors.

Step 3: Decorate Like a Pro (Or Just Have Fun!)

Now comes the best part—decorating! Use a butter knife or small offset spatula to spread your colored frostings over each brownie rectangle. Grab your black writing gel or cookie icing to add spider webs, jack-o’-lantern faces, or ghostly outlines. Sprinkle on your candies and spooky decorations to bring your creepy creations to life. There’s no wrong way to do this—just let your imagination run wild. I discovered that setting aside a “decoration station” with all your candies and frostings laid out makes this step easier and way more fun for everyone involved.

How to Serve Make-Your-Own Halloween Brownies Recipe

Garnishes

For garnishes, I stick with a mix of candy eyeballs and mini sprinkles—it’s a quick way to inject personality without getting too fussy. Plus, the eyeballs are just plain hilarious and perfect for Halloween vibes. If you want to get extra spooky, sprinkle a tiny pinch of edible glitter on some brownies—it adds a magical shimmer that’s super impressive when the lights go low.

Side Dishes

This Halloween brownies recipe pairs wonderfully with a glass of cold milk or even a warm cup of spiced apple cider. For a party, I like to serve it alongside some Halloween-themed popcorn or pumpkin spice cookies. These sweet combos balance the rich brownie flavors and keep the Halloween theme alive throughout the spread.

Creative Ways to Present

Presentation is everything for a festive occasion! One year, I arranged the brownies on a platter lined with fake spider webs and scattered plastic spiders around them—instant eerie effect. Another time, placing brownie rectangles on small black plates with orange napkins underneath made the colors pop beautifully. If you’re hosting kids, let them place their own decorated brownies on a tiered cake stand—it’s a fun and interactive display.

Make Ahead and Storage

Storing Leftovers

I always store leftover decorated brownies in an airtight container at room temperature. They stay fresh and soft for about 2 to 3 days—perfect if you want to enjoy them the next morning with your coffee. Avoid refrigerating unless your kitchen is very warm, as that can dry them out.

Freezing

Freezing decorated brownies can be a bit tricky because of the frosting, but I’ve found success by freezing the plain brownies first before decorating. Just wrap them tightly in plastic wrap and foil. When you’re ready, thaw overnight in the fridge and then add your frosting and decorations fresh. This keeps everything looking and tasting amazing.

Reheating

For reheating, I prefer eating these brownies cold or at room temp since you don’t want to melt the decorations. But if you want them warm, a quick 10-second zap in the microwave works—just be gentle. You could always warm your brownie without frosting separately if serving fresh is a must.
