Easy Halloween Brownies that are ready for your next party! This recipe is made with ingredients already in your pantry so you can start decorating right away with your kids, or alone if you want them to be perfect 🙂 Halloween theme desserts are so fun to make because there are so many fun ways to make them decorated to be fun and spooky.

Why I Love These Halloween Brownies

Now that we made the big move from Minnesota to Arizona to be close to my two grandkids, I’ve been working to make fun memories with them in the kitchen. It’s what my mom did with my kids and what my grandma did with us. Tradition is a big reason I do what I do for a living 🙂

These Halloween brownies were super easy to make because I had everything already in my pantry! And did you know that if you melt canned frosting in the microwave, it becomes the perfect coating for cookies, brownies, cakes, or cake pops? Just add a bit of food coloring. We had so much fun making (and eating) these yummy monster Halloween brownies together.

What Are Halloween Brownies

Because Halloween comes in so many different forms, brownies that carry the same theme also come in a variety of flavors, colors, and decorating. This ultra-simple version is made from either a boxed brownie mix, or your favorite homemade brownie recipe. Once they cool, they are cut, dipped in melted frosting, then decorated with chocolate sprinkles and candy eyeballs. Any colors or flavors of frosting can be used, along with the sprinkles you feel would be best.

How to Make Monster Brownies

Simple is the key to this Halloween Brownies recipe! And of course, fun when it comes to decorating them.

Bake the brownies according to the recipe or the directions on the side of the box. Be sure to line the pan with parchment paper so they will be easy to remove and cut.
Cool the brownies in the fridge for a couple of hours before cutting them with a knife you’ve warmed in hot water and dried off. These two tips will allow you to cut the brownies smoothly.
Melt the frosting in the microwave until runny. Divide it into small bowls and color them with the gel food coloring.
Dip the brownies in the melted frosting, or use a spoon to drizzle the frosting over the top. Set them on parchment paper.
Decorate with sprinkles and any other candy decorations you think would be fun. Let them cool for 15 minutes so the frosting firms up.

Halloween Brownies FAQs & Troubleshooting

How to Cut Cleanly Cut Brownies

There are a couple of game-changing tips for cutting brownies cleanly. And these tips work for all types of brownies…not just the Halloween variety 🙂

Line the baking pan with parchment paper so you can easily pull the whole sheet of cooked brownies out of the pan before cutting them.
Before you try to cut them, stick them in the fridge for a couple of hours, or even better would be an hour in the freezer. Either option allows the brownies to get firm, making them easier to cut.
Now that your brownies are firm and cold, let’s get your knife hot so it will glide right through. Grab a sharp chef’s knife and run it under some hot water. Dry it off.
Using short, little cuts, cut through the brownies. As soon as you see the slightest sign of the brownies sticking to the knife, carefully remove it, run it under the hot water, clean off any brownie mixture and keep going. Patience and a hot clean knife will get you perfect cuts every time.

If for some reason you still end up with some jagged edges, you still have hope! Because your Halloween brownies are dense and moist, you can easily fix them. Pick up each brownie and gently press the edges against the parchment paper on the countertop to square up your edges and get rid of those jagged edges.

My Frosting Didn’t Stay Melted

No worries! After the frosting is out of the microwave for about 10-15 minutes, it does begin to firm up again. Just toss the bowl into the microwave for another 20 seconds or so, stir it well, and you’ll be back to runny and melted. You can repeat this as often as needed as you are decorating the Halloween brownies.

How to Store Halloween Brownies

To store your adorable and spooky Halloween brownies, first be sure the frosting is set on each brownie. Once the frosting is firm, line an airtight container with a sheet of parchment paper and layer the brownies across the bottom. Add another sheet of parchment paper on top, then add another layer of brownies. To keep everything firm and not sticking together, store them in the fridge. They will last for up to 7 days in the fridge.

Can Halloween Brownies Be Frozen?

Yes, these spooky brownies can be frozen, even after they are decorated. Follow the same instructions for storing them in the fridge I listed above but place them in the freezer. They will last in the freezer for 3-4 months.

Halloween Brownie Decorating Variations

There is really no right or wrong way to make these spooky Halloween brownies. Use what you have on hand!

Use white frosting and make mummy brownies. Place the eye candies down first, then drizzle the melted frosting diagonally across each brownie to make them look like little mummies.
Bake the brownies in mini muffin pans and dip them in orange frosting to make little pumpkin brownies. Use a green Mike & Ike candy as the stem for each pumpkin brownie.
But the brownies into triangles and use white, orange, and yellow frosting to make candy corn brownies. Start with the yellow on the widest end and let it set before moving on to the orange. Again, let it set before dipping the tip into the white frosting.
