Frankenstein Marshmallows


To make Frankenstein Marshmallows, you will need the following ingredients:

  • Gelatin: Gelatin is the main ingredient that gives marshmallows their fluffy and chewy texture.
  • Sugar: Sugar adds sweetness to the marshmallows and helps in achieving the right consistency.
  • Corn syrup: Corn syrup is used to prevent the mixture from crystallizing and adds a smooth texture to the marshmallows.
  • Water: Water is necessary for dissolving the gelatin and sugar, and for creating the sugar syrup.
  • Vanilla extract: Vanilla extract enhances the flavor of the marshmallows and adds a hint of sweetness.
  • Green food coloring: Green food coloring gives the marshmallows their iconic Frankenstein appearance.

Tools and Equipment

Before we dive into the marshmallow-making process, let’s gather the necessary tools and equipment. You will need:

  • Mixing bowl: A large mixing bowl is essential for combining all the ingredients and whisking the mixture.
  • Whisk: A whisk will help you vigorously mix the ingredients together until they are well combined.
  • Candy thermometer: A candy thermometer is crucial for achieving the right temperature while preparing the sugar syrup.
  • Saucepan: A saucepan is needed to heat the sugar syrup mixture.
  • Mold: A Frankenstein-themed mold will help you shape the marshmallows into their iconic design.
  • Piping bag: A piping bag will allow you to easily fill the mold with the marshmallow mixture.

Preparing the Marshmallow Mixture

Now that we have all our ingredients and tools ready, it’s time to start preparing the marshmallow mixture. Follow these steps to ensure successful marshmallow making:

Step 1: Bloom the gelatin

In a mixing bowl, combine the gelatin with half a cup of water. Let it sit for about 5 minutes until the gelatin absorbs the water and becomes soft.

Step 2: Making the sugar syrup

In a saucepan, combine the sugar, corn syrup, and half a cup of water. Place the saucepan over medium heat and stir until the sugar has completely dissolved. Attach the candy thermometer to the side of the saucepan, making sure it doesn’t touch the bottom.

Step 3: Combining gelatin and syrup

Once the sugar syrup reaches a temperature of 240°F (115°C) on the candy thermometer, remove it from the heat. Slowly pour the hot sugar syrup into the bloomed gelatin while continuously whisking. Be careful as the mixture will be extremely hot.

Step 4: Adding flavor and color

Add the vanilla extract and a few drops of green food coloring to the mixture. Continue whisking until the mixture becomes thick and starts to cool down.

Shaping the Frankenstein Marshmallows

Now that our marshmallow mixture is ready, it’s time to shape them into cute Frankenstein characters. Let’s break down the shaping process into easy-to-follow steps:

Step 1: Choosing a mold

Select a Frankenstein-themed mold that has the desired size and shape for your marshmallows. You can find various Frankenstein molds in specialty baking stores or online.

Step 2: Coating the mold

To prevent the marshmallow mixture from sticking to the mold, lightly grease it with cooking spray or vegetable oil.

Step 3: Filling the mold

Transfer the marshmallow mixture into a piping bag and carefully fill each cavity of the mold. Make sure to fill them up completely while avoiding any air bubbles.

Step 4: Tapping out air bubbles

Gently tap the filled mold on the countertop to release any air bubbles that may be trapped inside the marshmallow mixture. This will ensure that your Frankenstein marshmallows have a smooth and flawless appearance.

Step 5: Letting the marshmallows set

Allow the marshmallows to set at room temperature for at least 4 hours, or overnight for best results. Once set, carefully remove them from the mold by gently pushing on the bottom of each cavity. Your Frankenstein marshmallows are now ready for the next step!

Decorating the Marshmallows

The fun part of making Frankenstein Marshmallows is decorating them to create cute and spooky faces. Let’s unleash our creativity with the following steps:

Step 1: Preparing the decorating supplies

Gather a variety of decorating supplies such as black food coloring, edible markers, small candies, and icing tubes. These supplies will be used to bring the Frankenstein faces to life.

Step 2: Creating Frankenstein faces

Use the black food coloring or edible markers to draw the eyes, nose, and mouth of each marshmallow. Get creative and make each face unique by adding stitches or scars to make them look like real Frankensteins.

Step 3: Adding other decorations

To enhance the intimidation factor, you can use icing tubes to add details such as eyebrows, hair, or bolts on the sides of the marshmallows. Small candies can be used as buttons on the marshmallow’s body for an extra touch of fun.

Storing and Serving

After putting so much effort into creating these delightful Frankenstein Marshmallows, it’s important to know how to store them and serve them in the best possible way. Follow these steps:

Step 1: Proper storage

Store the Frankenstein Marshmallows in an airtight container at room temperature. They can last up to 2 weeks if stored properly. Avoid exposing them to direct sunlight or high humidity.

Step 2: Creative serving ideas

Frankenstein Marshmallows can be enjoyed on their own or used to decorate Halloween-themed desserts. You can serve them alongside hot cocoa, use them as toppers for cupcakes, or even skewer them with lollipop sticks to create marshmallow pops.

Variations and Customizations

While the classic Frankenstein Marshmallows are a hit, why not experiment with different variations and customizations to suit your taste and occasion? Here are a few ideas to get you started:

Different colors

Instead of green, try using other food coloring shades such as purple, orange, or even red to create an army of colorful Frankensteins.

Alternative flavors

In addition to vanilla extract, you can experiment with other flavors such as almond, mint, or even pumpkin spice to give your marshmallows a distinct taste.

Additional decorations

Get creative and explore other decoration options such as edible glitter, chocolate drizzles, or even colorful sprinkles to add uniqueness to your Frankenstein Marshmallows.

Seasonal themes

While Frankenstein Marshmallows are perfect for Halloween, you can adapt the concept to other seasonal themes. For example, you can create marshmallow monsters for a spooky-themed birthday party or marshmallow snowmen during the winter holidays.

Tips and Tricks

To ensure the best results while making Frankenstein Marshmallows, consider the following tips and tricks:

Tip 1: Use a candy thermometer

Using a candy thermometer is crucial for achieving the right temperature of the sugar syrup. This will help you achieve the desired consistency and texture of the marshmallows.

Tip 2: Control the gelatin firmness

If you prefer softer marshmallows, reduce the amount of gelatin used. On the other hand, if you prefer firmer marshmallows, increase the amount of gelatin slightly.

Tip 3: Experiment with flavors and colors

Don’t be afraid to experiment with different flavors and colors. These customizations will add a personal touch to your Frankenstein Marshmallows and allow you to explore endless possibilities.
