Decadent Homemade Chocolate Marshmallows

As a child, I always looked forward to the holidays, not just for the presents, but for the homemade treats my grandmother would painstakingly create. Among the sea of cookies and fudge, there was always a plate piled high with her chocolate marshmallows. They were pillowy soft, intensely chocolatey, and utterly addictive. Each bite was like a warm hug, a sweet reminder of family, love, and the magic of the season. Recreating them brings me right back to her cozy kitchen.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 15-20 minutes
• Total Time: 10+ hours (mostly setting time)
• Yields: Approximately 16 marshmallows
• Dietary Type: Not Vegan, Not Gluten-Free, Not Dairy-Free

Ingredients

• 1/3 cup cocoa powder, plus 4 tablespoons cocoa powder, divided
• 1 1/4 cups water, plus 2 tablespoons water, divided
• 3 tablespoons gelatin (equivalent of 3 packets)
• 2 cups granulated sugar
• 3/4 cup light corn syrup
• 1/2 cup powdered sugar
• 2 tablespoons cornstarch
• 12 ounces chopped chocolate (optional) or 12 ounces chocolate coating (optional)

Equipment Needed

• 9×13 inch pan
• Aluminum foil
• Nonstick cooking spray
• Small microwave-safe bowl
• Whisk or spoon
• Large stand mixer
• Medium saucepan
• Candy thermometer
• Pastry brush
• Waxed paper
• Large, smooth-bladed knife

Instructions

1. Begin by preparing a 9×13 inch pan. Line it thoroughly with aluminum foil, ensuring the foil extends over the edges for easy removal later. Generously spray the foil with nonstick cooking spray to prevent sticking.

2. In a small, microwave-safe bowl, combine 1/4 cup water and 2 tablespoons water. Microwave on high for 2 minutes, or until the water is hot but not boiling. Carefully pour 1/3 cup cocoa powder over the hot water. Stir or whisk vigorously until the cocoa is completely dissolved and the mixture is smooth.

3. In the bowl of a large stand mixer, place 1/2 cup cold water. Sprinkle 3 tablespoons gelatin evenly over the surface of the cold water. Stir briefly to ensure the gelatin is distributed throughout the water. Let the gelatin sit undisturbed for at least 5 minutes to allow it to bloom and dissolve. This is a crucial step for achieving the right marshmallow texture.

4. Gently spoon the warm cocoa mixture into the bowl with the bloomed gelatin. Stir or mix on low speed until the cocoa and gelatin are thoroughly combined. Ensure there are no clumps of undissolved gelatin or cocoa.

5. In a medium saucepan, combine the remaining 1/2 cup water, 3/4 cup light corn syrup, and 2 cups granulated sugar. Place the saucepan over medium-high heat and stir continuously to dissolve the sugar. Once the sugar is dissolved, insert a candy thermometer into the mixture, making sure it doesn’t touch the bottom of the pan.

6. Allow the sugar mixture to cook without stirring until it reaches 240 degrees Fahrenheit on the candy thermometer. This is the “soft-ball” stage. As the mixture cooks, occasionally brush down the sides of the pan with a wet pastry brush to prevent sugar crystals from forming. Crystallization can ruin the smooth texture of the marshmallows. While the sugar mixture cooks, briefly run the stand mixer on low speed once or twice to ensure the gelatin and cocoa mixture remains well-mixed.

7. Once the sugar mixture reaches 240 degrees Fahrenheit, immediately remove it from the heat. Turn the stand mixer to low speed. Carefully and slowly pour the hot syrup into the mixer bowl with the gelatin and cocoa mixture. Be extremely cautious, as the syrup is very hot and can cause severe burns. If you have a large (at least 3 cup) liquid measuring cup with a spout, transferring the hot syrup to the cup before pouring it into the mixer can make this step easier and safer.

8. Gradually increase the speed of the mixer until it is running on high. Whip the marshmallow mixture for 15-20 minutes, or until it becomes very stiff and shiny. The mixture will significantly increase in volume. You can tell it is done when you stop the mixer and lift the beater; the marshmallow will slowly drip back down into the bowl in a thick, shiny stream.

9. Pour the whipped marshmallow into the prepared 9×13 inch pan. Use a spatula to smooth the top evenly. Allow the marshmallow to sit and firm up at room temperature for at least 10 hours, or preferably overnight. This is essential for the marshmallows to set properly. Do not attempt to speed up the process by refrigerating, as this will affect the texture.

10. Sift together the 1/2 cup powdered sugar, 4 tablespoons cocoa powder, and 2 tablespoons cornstarch. Cover your workstation with waxed paper to protect it and prevent sticking. Liberally sprinkle the surface of the waxed paper with the sugar/starch mixture. Sprinkle the top of the firmed marshmallow with the remaining sugar/starch coating.

11. Carefully flip the marshmallow face down onto the prepared surface. Gently peel back the aluminum foil from the marshmallow. Spray a large, smooth-bladed knife with nonstick cooking spray, and coat both sides of the blade with the powdered sugar/starch mixture.

12. Cut the marshmallow into squares, coating the knife blade with the sugar/starch mixture as needed to prevent sticking. Roll the cut edges of the marshmallows in the coating mixture so that all sides are smooth and not sticky. The size of the squares is up to your preference.

13. If desired, melt 12 ounces chocolate coating (or temper 12 ounces chocolate) according to the package directions or your preferred method. Dip the cut marshmallows halfway into the chocolate. The chocolate needs to be able to set without refrigeration (which will ruin the texture of the marshmallows), so use only tempered chocolate or chocolate coating for dipping. Place the chocolate-dipped marshmallows on a sheet of waxed paper to set.

14. To store the marshmallows, place them in a dry, airtight container in a temperate, dry location. Do not refrigerate them or keep them in a very humid place. Fresh marshmallows go stale after about a week, so these are best eaten soon after they are made.

Expert Tips & Tricks

• Bloom the Gelatin Properly: This is key to the marshmallow’s structure. Ensure the gelatin is fully dissolved before adding the hot sugar syrup.
• Candy Thermometer Calibration: Verify your candy thermometer is accurate. An off-calibration thermometer can lead to undercooked or overcooked marshmallows.
• Avoid Crystallization: Brushing down the sides of the pan with a wet pastry brush during the sugar syrup cooking process is crucial to prevent sugar crystals from forming, resulting in a smoother texture.
• Whipping Time: Don’t cut short the whipping time. The mixture needs to be whipped until it’s very stiff and shiny. This incorporates air and gives the marshmallows their signature fluffy texture.
• Flavor Enhancements: For a deeper chocolate flavor, try using Dutch-processed cocoa powder. A pinch of salt can also enhance the sweetness and chocolate notes.
• Cutting Neatness: Keep a bowl of the powdered sugar/cornstarch mixture nearby while cutting. Dip the knife in the mixture before each cut for clean lines.
• Chocolate Tempering: If you choose to dip the marshmallows in chocolate, proper tempering is essential for a glossy, stable finish. Otherwise, use chocolate coating for ease.

Serving & Storage Suggestions

These homemade chocolate marshmallows are delightful on their own or as a decadent addition to hot chocolate. They can also be used in s’mores or as a topping for desserts. To serve, arrange them artfully on a platter, perhaps dusted with extra cocoa powder or drizzled with melted chocolate. Store leftover marshmallows in an airtight container at room temperature for up to one week. Avoid refrigeration, as it can make them sticky.

FAQs (Frequently Asked Questions)

Q: Can I use honey instead of corn syrup?
A: While you can try honey, it will change the flavor and possibly the texture of the marshmallows. Corn syrup helps prevent crystallization and creates a smooth consistency.

Q: Why are my marshmallows sticky?
A: Sticky marshmallows are usually caused by high humidity or undercooking the sugar syrup. Ensure you reach the correct temperature and store them in an airtight container in a dry environment.

Q: Can I make these without a stand mixer?
A: While a stand mixer is recommended for the long whipping time, you can use a hand mixer. Be prepared for a longer whipping process and ensure your mixer is powerful enough.

Q: How do I temper chocolate for dipping?
A: Tempering chocolate involves carefully heating and cooling it to specific temperatures to create a stable, glossy finish. There are many guides online, but using chocolate coating is an easier alternative.

Q: Can I freeze these marshmallows?
A: Freezing marshmallows is not recommended, as it can alter their texture and make them sticky upon thawing. They are best enjoyed fresh.
