Creating Christmas Marshmallows is easy if you follow these simple steps:

1. Prepare the Baking Pan: Lightly grease a 9×13-inch baking dish with non-stick spray and dust with powdered sugar. Set aside.
2. Bloom the Gelatin: In a small bowl, combine the gelatin with ½ cup of cold water. Let it sit for about 10 minutes to bloom.
3. Combine Sugar Ingredients: In a medium saucepan, combine granulated sugar, corn syrup, and ½ cup of water. Cook over medium heat, stirring until the sugar dissolves.
4. Bring to a Boil: Increase the heat and bring the mixture to a boil without stirring. Use a candy thermometer to check the temperature.
5. Heat to 240°F: Allow the mixture to boil until it reaches 240°F (soft ball stage). Remove from heat.
6. Mix Gelatin and Sugar: Add the bloomed gelatin to the hot sugar syrup. Stir until completely dissolved.
7. Whip the Mixture: In a stand mixer, beat the mixture on high speed for about 10-15 minutes until it becomes thick and fluffy. Add vanilla extract and peppermint extract, if using.
8. Add Color: If you want colored marshmallows, divide the mixture into separate bowls and add a few drops of food coloring. Stir gently until blended.
9. Pour into Prepared Pan: Pour the marshmallow mixture into the prepared baking dish. Use a spatula to spread it evenly.
10. Set: Allow the marshmallows to set at room temperature for at least 1 hour or until firm.
11. Cut and Dust: Once set, dust a clean surface with powdered sugar. Turn the marshmallow slab out onto the surface and cut into squares. Dust the cut sides with more powdered sugar to prevent sticking.

These steps will guide you in creating these incredible marshmallows effortlessly.
