How to Make Cocoa Marshmallows
Start by greasing and lining an 8-inch square pan with parchment paper. Mix powdered sugar, cornstarch, and cocoa powder, then dust some over the pan and save the rest for coating. Sprinkle gelatin over ¼ cup cold water in a stand mixer bowl and let it soften. Meanwhile, heat the remaining water, sugar, corn syrup, and salt in a saucepan until the sugar dissolves, then cook until the syrup reaches 240°F. Carefully pour the hot syrup over the gelatin and beat until thick, fluffy, and light. Add cocoa powder and vanilla, then mix until smooth. Pour into the prepared pan, smooth the top, and dust with the remaining cocoa mixture. Let it set at room temperature for 4–6 hours, then lift it out, cut into squares with a lightly greased knife, and coat each piece with the remaining cocoa mixture.
What Do Cocoa Marshmallows Taste Like?
Cocoa marshmallows have the familiar sweetness of traditional marshmallows with a noticeable chocolate flavor. Unsweetened cocoa powder adds a rich, slightly deep cocoa taste without making the marshmallows too heavy. The finished marshmallows should be soft, fluffy, and chewy. The cocoa coating gives the outside an additional chocolate flavor and helps keep the individual pieces from sticking together.
Tips for Making Soft Cocoa Marshmallows
Use a candy thermometer when preparing the sugar syrup so you can reach the correct temperature. The syrup temperature plays an important role in the final texture.
Allow the gelatin to soften before adding the hot syrup. This helps it combine properly with the sugar mixture. Give the marshmallow mixture enough time to whip. It should become thick, fluffy, and noticeably lighter before you transfer it to the pan.
When cutting the finished marshmallow, lightly grease the knife to make the process easier. Dusting the pieces with the cocoa coating mixture also helps prevent them from sticking together.
How to Get a Stronger Chocolate Flavor
For a deeper cocoa flavor, you can add a little more cocoa powder to the mixture. Add it gradually because a large amount can affect the texture.
Another simple option is to give the finished marshmallows a slightly heavier cocoa coating. This adds more chocolate flavor without changing the marshmallow mixture itself.
How to Serve Cocoa Marshmallows
These chocolate marshmallows are especially good with hot chocolate. Drop a few into a warm drink and let them soften slightly for an extra chocolate treat.
They can also be served on a dessert plate, added to a s’mores spread, or enjoyed as a simple homemade snack. For a party or gathering, arrange them on a serving plate and lightly dust them with cocoa powder before serving.
Cocoa Marshmallows for S’mores
Cocoa marshmallows can add another layer of chocolate flavor to s’mores. Place a toasted cocoa marshmallow between graham crackers with chocolate for a richer version of the classic treat.
The marshmallows can be toasted carefully over heat just like regular marshmallows. The outside will become lightly browned while the center becomes soft and warm.
How to Store Cocoa Marshmallows
Place the finished marshmallows in an airtight container and keep them in a cool, dry place. If you need to stack them, use parchment paper between the layers. Try to keep them away from humidity because moisture can make the marshmallows sticky and change their texture.
Can You Freeze Cocoa Marshmallows?
Freezing can change the texture of homemade marshmallows, so the best way to freeze marshmallows is to store them properly in an airtight container, although room-temperature storage in a tightly sealed container is generally a better option. Make sure the container remains closed when the marshmallows are not being served.
Frequently Asked Questions
Can I use hot cocoa mix instead of cocoa powder?
Unsweetened cocoa powder works best for this recipe because hot cocoa mix can contain additional sugar and other ingredients that may affect the sweetness and texture.
Why are my cocoa marshmallows sticky?
Moisture can make homemade marshmallows sticky. A cocoa, powdered sugar, and cornstarch coating helps reduce sticking and makes the pieces easier to handle.
How long do cocoa marshmallows need to set?
Allow them to set for about 4 to 6 hours, or until the marshmallow is firm enough to remove from the pan and cut.
Can I use cocoa marshmallows in hot chocolate?
Yes. Their chocolate flavor makes them a natural topping for hot chocolate.
Can I toast cocoa marshmallows?
Yes. Cocoa marshmallows can be toasted carefully, just like regular marshmallows. The outside will brown while the inside becomes soft.
How should I cut homemade cocoa marshmallows?
Use a lightly greased knife and cut the set marshmallow into squares. Coat the pieces with the cocoa mixture afterward to reduce sticking.
