  • 1 Candy thermometer or digital thermometer
  • 1 Silicon spatula
  • Stand-Up Mixer (with the whisk attachment) or electric hand mixer


Prep the Pan:

  • 3 tablespoons powdered sugar
  • 1 tablespoon corn starch


  • 3/4 cup cold water divided
  • 3 envelopes of gelatin 7 1/2 teaspoons 
  • 1 1/2 cups white granulated sugar
  • 1 cup light corn syrup 
  • 1/2 teaspoon kosher salt 
  • 1/2 teaspoon peppermint extract
  • Blue and Yellow Food Coloring 
  • 1/2 cup cocoa nibs chopped, reserving a tablespoon to sprinkle over the top


To Prep the Baking Dish:

  • Before you begin, let's do some prep. Start by sifting together powdered sugar, corn starch onto a large plate. Grease you 8x8-inch casserole dish or baking dish. If you don't have one, you could use a variety of dishes. We're using this to set the marshmallows.
  • Rub the dish with a bit of neutral oil in one even layer. Add a teaspoon of the powdered sugar mixture to the casserole dish and shake it around until the bottom of the edges are dusted. Set aside.

To Make the Marshmallows:

  • To the bowl of your stand-up mixer (or a large bowl if you're using an electric hand mixer), add 1/2 cup of water and sprinkle the gelatin on top; allow to sit for 10 minutes. Attach the bowl to the stand-up mixer and add the whisk attachment.
  • Meanwhile, in a medium saucepan, combine the granulated sugar, corn syrup, salt and remaining 1/4 cup of water. Heat the mixture over medium heat until the sugar has dissolved. Turn the heat up to moderately high heat and bring the mixture to a hard boil and cook for 1 minute, until the candy thermometer or digital thermometer reads 240 degrees F.
  • Lower the whisk attachment and turn the machine on low. Carefully add the boiling liquid to the gelatin mixture. Turn the mixer to high and beat for 5 minutes, until the mixture has grown in volume. Stop the mixer and add 12 to 15 drops of each food coloring—this will make the perfect shad of “mint green."
    *If you're using a large bowl, simply add the hot mixture and turn the electric hand mixer on low being sure it doesn't splatter. After a minute or so, increase the speed to high and beat for 4-5 minutes. Proceed with recipe above and below.
  • Beat again for an additional 3 minutes, until doubled in volume and until it holds stiff peaks. Add the peppermint extract and vanilla extract. Beat for an additional minute or so until the both of them are incorporated. Fold in the cocoa nibs.
  • Pour the mixture into the prepared baking pan, smoothing out the top until it's evenly disbursed (it'll be sticky!). Sprinkle the remaining cocoa nibs on top. Lightly cover with plastic wrap.
  • Allow it to firm up on the kitchen counter for about 3 to 4 hours. Take a knife and run it around the edges of the casserole dish or pan and invert the marshmallow sheet onto a large cutting board, smacking the bottom of it, if needed. You also may need to use your fingers to loosen the marshmallow sheet from the casserole dish and gently glide it onto the cutting board.
  • Using a sharp knife, cut the marshmallows into 2 or 3-inch squares. Store the marshmallows in an airtight container for up to 1 week.


Tips and Tricks:
  • Switch it up! Leave out the food coloring and peppermint extract. You'll end up with a more chocolate-chip and vanilla marshmallow.
  • Add in vanilla bean - If you want more flavor, add in the caviar from half of a vanilla bean. Yum!
  • Gift them - Toss up the cut up marshmallows with some of the leftover powdered sugar and corn starch mixture. Place them in a gift bag and tie a ribbon. The cutest homemade gift. You could even gift them alongside my Homemade Sugar Cubes or Homemade Vanilla Extract.
