Ingredients & Equipment Used In This Recipe
For your convenience, any specialized or notable ingredients and equipment needed to make these cupcakes have been listed below and linked to Amazon or other stores if available online. Standard ingredients such as flour or sugar are not listed, as you are likely to have those in your kitchen. The full list with measurements is found on the recipe card.
Cupcakes & Frosting Ingredients

- Food Coloring Gel – Red and Orange
Decorating Ingredients
- Black Fondant – to make the cauldrons
- Bright/Neon Green Fondant – to make the witch brew bubbles
- Tube/Pouch of Bright/Neon Green Frosting – to pipe into the cauldron
- Halloween Sprinkles – you can use any sprinkles that you like! Make a mix of your own with different single sprinkle types, or buy a ready-made mix. Whatever you use, you will want about 2 cups to decorate the cupcakes.

- Wire Cooling Rack
- Fondant Tools
- Large Piping Bag – you can use disposable or reusable, your choice.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog! I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, liters, etc.,).
Cauldron Cupcake Recipe Tips
The cauldrons to decorate these cupcakes are made with fondant (also known as sugarpaste).
Fondant needs time to dry before using as cake decorations, so allow up to 24 hours to get the pieces made before making and decorating your cupcakes.
Fondant Tips
If you have never worked with fondant before, don’t panic – it is really easy to use, follow my tips and you’ll be just fine!
- Line a cookie sheet(s) or tray(s)with parchment paper or a non-stick baking mat to place the fondant pieces on to dry.
- Dust your work surface with powdered sugar (icing sugar/confectioner’s sugar) or cornstarch (cornflour) so that the fondant doesn’t stick. Think of it like the way you use flour when rolling dough.
- Rub a little powdered sugar/cornstarch into your hands and knead a handful of the fondant to make it more pliable before rolling, rather than using it straight from the package.
- If there is excess powdered sugar on the pieces, you can gently brush away with a pastry brush, or an unused, clean paintbrush.
- Alternatively, you can use a vodka spray. Pour some vodka into a mini spray bottle and gently mist the fondant wings. Vodka dries quicker than water which is why it is usually used when handling fondant.
- Always make extra pieces – that way if some break or you have another mishap, you have got backups that you can use.
- Leave the fondant cauldron to harden in a cool, dry place – do not place them in the fridge.
- The fondant pieces should be solid enough to handle and place on the cupcakes after 3 – 6 hours. I personally like to leave fondant pieces to dry for around 24 hours. How long this takes, however, is based on the size and thickness of the fondant, and how humid your house is, so you will need to judge if they will hold up as they need to in the cupcakes.
- When making cakes or cupcakes that use fondant decorations I like to make them a few days ahead of time which allows for drying without stress. Fondant that isn’t dry enough can mean disappointing end results.
- After using fondant the surface will be super sticky (it always is in my experience!) so you will probably have to wipe away the sugar first, then give it a soapy hot wash over, and then another clean over! You can always buy a fondant rolling mat for easier cleanup.
- Always keep fondant covered when making decorations to prevent it from drying out. And when you’ve finished, wrap up any remaining fondant very well – I double wrap it in plastic wrap and place it in an airtight container. This keeps it fresh and you are able to use it for future cake making.
Cupcake Making Tips
- Use your choice of cupcake liners – themed to the cupcakes, plain white or black, or a complimentary color.
- Use an ice cream scoop to equally divide the cupcake mixture between the cupcake liners. Fill them about three-quarters full.
- The cupcakes should be ready in about 20 minutes – test their doneness by inserting a toothpick into the cakes. It should come out clean when the cupcakes are cooked all the way through. Bake for an extra 2 minutes and check again.
- Cool the cupcakes in the pan for 5 minutes before transferring them to a wire rack to cool completely before frosting.
Cupcake Frosting Tips
- When making the frosting you want the end result to be creamy, smooth, and hold a stiff peak. You may have to adjust the amount of powdered sugar and cream slightly to achieve the consistency you need.
- The frosting is then divided and colored using food coloring. Remember that you can always add more color, but not take it away. Add a little to start with and add more to get the shade required.
- FOOD COLORING! Food coloring is available in various forms. You’re most likely to find liquid coloring in your grocery store, and other types of coloring like gels, pastes, and powders in more specialised cake decorating shops. The cheapest option is liquids, but they can alter the consistency of your frosting and cake batter, so I prefer to use pastes or gels which don’t. A little goes a long way with food coloring gels and you can usually get a much deeper shade than you would with liquids.
- These cupcakes are double-frosting, a scoop of frosting is placed on each cupcake, then flattened and rounded off using a knife or angled spatula to create the base for lots of sprinkles.
- SPRINKLES! Following the color theme provided in the recipe, you can use any type you like such as nonpareils, jimmies, stars, confetti, pearls, or shapes – you’ll need about 2 cups of them in total to cover the cupcakes.
- A mixture of red and orange frosting is piped on top of the sprinkles layer to look like a fire, and the fondant cauldron is placed on top.
- Use a piping bag fitted with a star tip for the two-color frosting.
- There are two ways you can do multi-color frosting:
- Scoop half the side of the piping bag with white frosting and the other half with orange, then squeeze some frosting out until the two colors combine.
- Or, use the double piping bag by putting a piping bag of each color into another piping bag fitted with the tip and frosting as usual. Wilton has a great demonstration video on YouTube that I highly recommend.
- If you feel like you are going to be making a lot of cakes and cupcakes in the future, I think it is worth investing in a set of piping tips so that you know you always have the right ones on hand for a recipe.
- Do not overfill the piping bag with frosting, and make sure you squeeze the frosting down the bag to expel any air bubbles and to combine the two colors.

Instructions
- Use cornstarch as you would flour when making dough. Gently dust your work surface and hands.
- Pinch off about 2 tablespoons of the black fondant and roll it into a ball.
- Using a fondant tool with a round ball at the end (it's called a ruffle fondant tool) make a small hole in the top of the ball by pushing the tool into the fondant.
- Make a deeper, winder hole by working the tool around in the small hole you just made.
- Use your fingers to mold the fondant ball into a cauldron shape. Roll out a thin sausage shape of black fondant and wrap it around the top of the hole to create the lip of the cauldron. Make 18 cauldrons (and a few extra in case of breakage!)
- Pinch off about 2 teaspoons of green fondant, and roll into a ball. This will be the largest "bubble" Make 18 large bubbles (and a few extras just in case!)
- Repeat step with the more green fondant to make 5-6 smaller "bubbles" per cauldron. Make 90 – 108 smaller bubbles (and some extras as before.
- Pipe some green frosting into the cauldron, and place the green bubbles on top to resemble a bubbling cauldron. Add extra frosting to get the look you desire for your cupcake cauldrons. Set aside to dry while you make the cupcakes. These fondant decorations do not have to dry hard.
- Preheat oven to 350°F/180°C/Gas 4 degrees. Line cupcake pans with 18 black cupcake liners and set them aside.
- To make the cupcakes, use an electric handheld or standing mixer, and beat the chocolate cake mix, eggs, milk, and oil until combined.
- Use an ice cream scoop to divide the cupcake batter between the 18 cupcake liners, filling about ¾ way full.
- Bake for 20 minutes or until a toothpick inserted into the center of the cupcake comes out clean.
- Leave to cool for 5 minutes in the pan and then transfer to a wire rack to cool completely before decorating.
- To make the frosting, use an electric handheld or standing mixer, and beat the butter, powdered sugar, vanilla, and heavy whipping cream together until combined, smooth and stiff peaks form.
- Remove two ¾ cups of frosting from the bowl and place them into two separate smaller bowls.
- Add red food coloring to one of the smaller bowls and mix until combined and to your desired shade of red,
- Add orange the food coloring to one of the smaller bowls and mix until combined and to your desired shade of orange,
- Scoop the red frosting into one side of a piping bag fitted with a star tip and the orange frosting on the other side. Set it aside.
- Scoop a mound of white frosting onto the cupcake using a medium ice cream scoop and smooth and flatten into a thick round disk.
