What You’ll Need

- One box of your favorite brownie mix (plus the ingredients called for on the box, like eggs, oil, and water)
- 1/2 cup of vibrant green frosting (you can use store-bought or make your own!)
- A variety of Halloween candies and sprinkles for decorating (think gummy worms, candy corn, spooky sprinkles, and anything else that screams Halloween!)
Cooking Method, Step by Step
Step 1: Bake the Brownies
Preheat your oven according to the instructions on the brownie mix box. Grease a baking pan and prepare the brownie batter as directed on the box. Pour the batter into the prepared pan and bake as instructed.
Step 2: Cool the Brownies
Once the brownies are baked, let them cool completely in the pan. This is an important step to prevent the frosting from melting later.
Step 3: Frost the Brownies
Once the brownies are cool, frost the entire top surface of each brownie with a generous layer of green frosting, spreading it evenly.
Step 4: Decorate the Brownies
Now comes the fun part! Decorate the frosted brownies with your assortment of Halloween candies and sprinkles. Get creative and make them look like bubbling witch’s cauldrons. Gummy worms can look like creepy crawlies, and colorful sprinkles can resemble magical potions!
Step 5: Serve and Enjoy!
Cut the brownies into squares and serve. These WITCH’S CAULDRON BROWNIES are perfect for Halloween parties, spooky movie nights, or any occasion that calls for a fun and festive treat.
Test-Kitchen Tips

- For extra fudgy brownies, slightly underbake them. Check for doneness a few minutes before the recommended baking time.
- If you’re using store-bought frosting, let the brownies cool completely before frosting them, or the frosting might melt. You can see how to make this in our Lunch recipes!
- Don’t be afraid to get creative with your candy decorations. The more, the merrier!
