Homemade Chocolate Marshmallows

This looked so good, i had to post it here for safe keeping. i mean what could be better than chocolate marshmallows? i got this off about.com. I'm guessing at the quantities and time.

Steps

Prepare a 9x13 pan by lining it with aluminum foil and spraying the foil liberally with nonstick cooking spray.

Place 1 / 4 cup plus 2 tbsp water in a small microwave-safe bowl , and microwave for 2 minutes.

Pour 1 / 3 cup cocoa powder over the hot water , and stir or whisk to dissolve the cocoa.

Place 1 / 2 cup cold water in the bowl of a large stand mixer.

Sprinkle the gelatin on top and stir briefly to distribute.

Let gelatin sit and dissolve for at least 5 minutes.

Spoon warm cocoa mixture into gelatin , and stir or mix on low to thoroughly combine.

Place remaining 1 / 2 cup of water , corn syrup , and sugar in a medium saucepan over medium-high heat.

Stir to dissolve the sugar , and insert a candy thermometer.

Allow the mixture to cook without stirring until it reaches 240 degrees on the thermometer.

Brush down the sides occasionally with a wet pastry brush to avoid crystallization.

While the candy cooks , briefly run the mixer on low once or twice to ensure the gelat.
