How To Make Marshmallow Peeps

Makes about 12 Peeps

What You Need

Ingredients 
To make the marshmallows:
7 1/2 teaspoons unflavored gelatin (I used 3 Knox gelatin envelopes)
1 1/2 cups granulated sugar
1 cup light corn syrup
1/2 teaspoon salt
1 tablespoon vanilla extract
Food coloring

To decorate the Peeps:
Butter for greasing pans (and your fingers)
1 tablespoon cornstarch
1 tablespoon powdered sugar
Sanding sugars
Food coloring
Smoked sesame seeds (for eyes of Peeps)

Equipment
Stand mixer 
Medium-sized pot
Candy thermometer (I used this one)
2 cake pans (or a pie pan or sheet pan would do fine)
Stiff spatula
Cookie cutters

Instructions

1. Prepare the pans: Lightly grease two pans or one larger one and pour the marshmallow into the pans and set aside.
2. "Bloom" the gelatin: Place the contents of the three gelatin envelopes in the bottom of the bowl of the stand mixer. Add 1/2 cup of cold water and set aside while preparing the next part of the recipe.
3. Prepare the sugar syrup: In a medium-sized pot, heat the sugar, corn syrup, salt, and vanilla over high heat. When mixture has come to a full rolling boil, stop stirring, but swirl the pan occasionally by the handle. Attach a candy thermometer to the pot and let the mixture heat to 240°F. This will take about 7 minutes.
4. Carefully whisk the sugar syrup into the gelatin: Attach the whisk attachment to your mixer. With the mixer on medium speed, carefully pour the hot sugar syrup into the bowl. When all the syrup has been added, pour in another 1/2 cup of water.
5. Increase speed to high and beat for 12 to 15 minutes: After 5 minutes, the mixture will be opaque, but still very liquidy. After 10 minutes, the marshmallow has started to come together, but is still a bit soft. After 12 to 15 minutes, the marshmallows are thick, fairly stiff, and ready.
6. Add food coloring: I divided my marshmallow into 2 parts, for 2 colors. It took about 12 to 15 drops of food coloring to achieve the pale pastel color I wanted.
7. Transfer the marshmallow into prepared pans. This is a very messy, sticky job! It can help to grease your fingers and also have a spare plate or tray nearby to set your utensils down.
8. Let the marshmallow set for at least 4 hours or overnight.
9. Turn out the marshmallow blocks onto a flat surface: When you're ready to make the Peeps, just turn the marshmallow out onto a flat surface and gather the cookie cutters.
10. Cut out your Peeps: Combine a little cornstarch and powdered sugar and dredge the cookie cutters in between cuts to make things smoother and less sticky.
11. Apply the sanding sugar: Dip your finger into a little water and coat the entire marshmallow. Dredge the marshmallow carefully in colorful sanding sugar. Let air dry on a cooling rack.
12. Make the Peep eyes: Use a little dab of corn syrup and a few smoked sesame seeds to create eyes on your creatures. I found a tip of a toothpick worked perfectly to apply the corn syrup and sesame seeds.
13. Enjoy your Peeps: Wrap up with cellophane, tie with a ribbon, and delight your friends. Peeps will keep in an airtight container for about a week.
