  • Unflavored Gelatin: essential for this recipe to work. It gives the marshmallows their structure and bouncy texture.
  • Cocoa Powder: provides the chocolate flavor. Use a good quality unsweetened cocoa powder for the best chocolate taste.
  • Water: divided in this recipe and used both to enhance the gelatin and make the simple syrup.
  • Granulated Sugar: creates the proper sweetness and structure needed for fluffy marshmallows.
  • Powdered Sugar: mixed with cocoa powder to coat the pan and prevent the marshmallows from sticking.

How to Make Chocolate Marshmallows

  1. Grease a 9 x 13 inch baking dish with butter or cooking spray. In a small bowl mix the powdered sugar with ¼ cup of the cocoa powder and lightly sift a thin coating over the greased baking dish.
  2. Add the gelatin and half a cup of cold water to the bowl of a stand mixer and let it sit (without stirring) while you prepare the simple syrup. This allows the gelatin to 'bloom.'
  3. In a saucepan combine the remaining water and granulated sugar. Cook over medium-high heat stirring constantly until the mixture reaches at least 240ºF and comes to a rolling boil. Then, take the syrup off the heat.
  4. Add the remaining ½ cup cocoa powder to the gelatin mixture. With the mixer on low, carefully pour the hot syrup into the mixing bowl a little at at time.
  5. Increase the mixer speed to high and beat for about 20 minutes until the mixture becomes lighter in color, thick, fluffy and glossy.
  6. Spread the marshmallow mixture evenly into the prepared baking dish with a spatula that has been oiled with cooking spray.
  7. Dust the top of the marshmallow mixture with more cocoa and powdered sugar mixture.
  8. Let sit at room temperature for at least 4 hours before slicing into 6 columns and 8 rows with a sharp knife that's been oiled with cooking spray.
  9. Dip all sides of each marshmallow into the cocoa and powdered sugar mixture to reduce stickiness. Slice into mini marshmallows if desired. Store in an airtight container at room temperature.

Helpful Tips

  • Lightly dust your knife with powdered sugar to prevent sticking while cutting.

Recipe FAQ

Are these marshmallows super sticky?

No, they are no stickier than store-bought marshmallows when properly coated.

Why are homemade marshmallows powdery?

They are lightly coated with a powdered sugar and cocoa mixture so they will feel slightly powdery when eaten. The powder absorbs over time during storage.

Do homemade chocolate marshmallows taste different?

They are fluffier, fresher, and have more chocolate flavor than packaged marshmallows.
