1. Measure 2 and a half teaspoons of agar agar powder into a small saucepan. Add half a cup of cold water and let it bloom for 5 minutes without stirring.

2. In a separate saucepan, combine sugar, corn syrup, and quarter cup of water. Bring to a boil over medium heat and cook without stirring until the mixture reaches 240°F on a candy thermometer. Meanwhile, heat the agar agar mixture over low heat until fully dissolved.

3. Pour the hot sugar syrup slowly into a stand mixer bowl with the dissolved agar agar. Add vanilla extract and whip on high speed for 8 to 10 minutes until thick, glossy, and holding stiff peaks.

4. Transfer marshmallow mixture to a piping bag with a round tip. Pipe chick or bunny shapes onto parchment paper dusted with powdered sugar. Work quickly as agar agar sets faster than pork gelatin.

5. Mix granulated sugar with gel food coloring in a small bowl. Once piped shapes have set for 10 minutes, roll or sprinkle each one with colored sugar. Allow to rest at room temperature for 1 hour before serving.
