How to Make Witch’s Brew Cauldron Brownies

  1. Make the Fondant Brew Sticks – You are simply going to take small bits of black fondant and roll them into somewhat thick ‘logs’. The hardest part of this step is remembering to prep these the day before. Your brew sticks will need to dry out overnight.
  2. Make the Brownies – This step is also simple since we are taking the short cut of using a boxed brownie mix. You are more than welcome to substitute in your favorite homemade brownies. But boxed mix is a great alternative for something quick and easy. You are going to need a family size box, or a 9×13 pan of homemade.
  3. Make the Frosting – I used a simple buttercream frosting recipe for these brownies. You are welcome to use your family’s favorite type of frosting. If you need to keep it just as easy as the brownies, you are welcome to use can frosting, just know that the food coloring will thin it out some. It might not sit up as well on the cauldrons as what’s in the pictures.
  4. Decorate the Cauldron Brownies – Once you have iced your brownies and cauldrons, you are going to add on your favorite Halloween sprinkles. I used a few of my favorite Wilton brand that I found in the baking section at Michaels.

Not a fan of fondant?

If you would prefer to skip the fondant on the brew stick, you have a few options for substitutions. You could leave it completely off; the brownies would still be adorable with the frosting and sprinkles. But to truly round out the witch’s cauldron, you need the stick! I would suggest using a pretzel stick or a cut piece of black licorice in its place. Chocolate covered pretzel sticks would be another great option!

Where can I find the cauldrons?

Since, with this recipe you are simply breaking up a full sheet pan of brownies and not trying to fit a full cupcake into a cauldron, you honestly could use any small plastic cauldrons you can find. Amazon, Michaels, even Wal-Mart or Target would more than likely have some type of cauldron in stock. I found mine in the Halloween baking section at Michaels.
