Chocolate Marshmallow Hearts Recipe tastes like fluffy vanilla clouds wrapped in snappy chocolate with a whisper of salt to keep each bite balanced. It uses basic pantry staples, so you keep the cost low without skimping on the candy-shop vibe. It fits Valentine gifting, date nights, and kid-approved treats, and the total time runs about 2 hours 40 minutes; I tested it after a long shoot and still found energy for a second piece.
Reasons To Try This Chocolate Marshmallow Hearts Recipe
These heart-shaped marshmallows deliver a creamy, bouncy center under a smooth chocolate shell. The flavor lands sweet but balanced, and the texture contrast makes every bite feel special.
You can pipe them into a silicone heart mold or spread the marshmallow in a pan and cut hearts. The chocolate coating sets cleanly, so the hearts stack well for gifting or party trays.
“I brought a box to game night, and they vanished before the cards hit the table. Soft, chocolatey, and miles better than store-bought.”
Ingredients You Need
- 2 envelopes unflavored gelatin, about 14 g total (Knox works great)
- 1/2 cup cold water, for blooming the gelatin
- 1 cup granulated sugar
- 1/2 cup light corn syrup (prevents crystallizing; honey works but adds flavor)
- 1/4 cup water, for the syrup
- 1/8 teaspoon fine sea salt
- 1 teaspoon vanilla extract (or 1/2 teaspoon almond or peppermint for a twist)
- 1/3 cup powdered sugar mixed with 1/4 cup cornstarch, for dusting
- 12 ounces chopped chocolate or melting wafers (dark, milk, or white; wafers save you from tempering)
- 1 teaspoon neutral oil, optional, to thin the chocolate slightly
- Optional toppings: crushed freeze-dried strawberries, toasted coconut, colored sprinkles, flaky salt
Shortcut option:
- 24 large store-bought marshmallows or seasonal heart-shaped marshmallows
- Extra powdered sugar for rolling and cutting
Equipment list:
- Stand mixer or hand mixer with large bowl
- Small heavy-bottomed saucepan
- Candy thermometer that reads to 240 F
- Silicone heart mold or an 8-inch square pan with parchment plus a small heart cookie cutter
- Piping bag or zip-top bag
- Rubber spatula
- Microwave-safe bowl for melting chocolate
- Sheet pan lined with parchment
Chef Tips
You can dial in candy-shop results with a few tiny moves.
- Keep the pan clean by brushing the sides with a wet pastry brush while the syrup boils. Sugar crystals jump ship fast.
- Hit 240 F on the nose. Syrup that runs cooler makes sticky marshmallows, and hotter makes them chewy.
- Grease the mold lightly, then dust with the sugar-cornstarch mix so the hearts pop out easily.
- Pipe or spread the marshmallow right after whipping. It firms up quickly.
- Seed the chocolate by stirring in a handful of finely chopped chocolate after melting. You get a snappier set without a full temper lesson.
- Tap the fork on the bowl after dipping each heart. Extra chocolate falls off and edges look neat.
- Garnish while the chocolate still looks shiny. Toppings stick better.
- Cool the coated hearts at room temp. A fridge can cause chocolate bloom and a dull finish.
How to Make Chocolate Marshmallow Hearts
- Prep Time: 30 minutes
- Cook Time: 10 minutes
- Total Time: 2 hours 40 minutes
- Bloom the gelatin: Add 1/2 cup cold water to the mixer bowl and sprinkle the gelatin over it. Let it sit while you cook the syrup.
- Cook the syrup: In a small saucepan combine sugar, corn syrup, 1/4 cup water, and salt. Clip on a thermometer, bring to a boil over medium, and cook to 240 F without stirring. Brush the sides with water to dissolve any crystals.
- Whip the base: Start the mixer on low. Stream the hot syrup into the gelatin. Increase to high and whip 8 to 10 minutes until very thick, glossy, and tripled in volume. Beat in vanilla.
- Prep the mold or pan: Lightly oil a silicone heart mold, then dust with the sugar-cornstarch mix. Or line an 8-inch pan with parchment and dust.
- Pipe or spread: Scoop the marshmallow into a piping or zip-top bag. Pipe into the heart cavities until level, or spread evenly in the pan and smooth the top.
- Set the marshmallow: Let it sit uncovered at room temperature for 2 hours until springy.
- Release or cut: Dust the tops, then release hearts from the mold. For the pan, lift the slab out, dust both sides, and punch out hearts with a greased cutter.
- Melt the chocolate: Microwave two thirds of the chocolate with the oil in 20-second bursts, stirring between each. When smooth, stir in the remaining chocolate until melted and fluid.
- Dip: Place a heart on a fork, dip, and lift. Tap the fork on the bowl to shake off excess. Set on parchment.
- Decorate: Sprinkle toppings while the chocolate still looks wet.
- Set the coating: Let the hearts sit 15 to 20 minutes until firm, or chill 5 minutes if your kitchen runs warm.
Shortcut Method
- Dust a board with powdered sugar. Roll large marshmallows with a rolling pin into 1/3-inch slabs and cut with a small heart cutter. Or use seasonal heart-shaped marshmallows as is.
- Melt the chocolate as above, dip the hearts, garnish, and set on parchment.
- Let the chocolate firm up at room temp before boxing or plating.
Different Ways to Try It
You can riff on these hearts and still keep the spirit of the recipe.
- Gluten-free: Most marshmallows qualify, but check labels. Use certified sprinkles and chocolate if needed.
- Vegan swaps: Use vegan marshmallows and dairy-free chocolate, or whip aquafaba marshmallow cream and pipe into molds.
- Low carb: Use sugar-free chocolate and a keto marshmallow base that uses allulose. Many stores now stock sugar-free marshmallows if you want a shortcut.
- Add-ins: Fold orange zest into the marshmallow, dust the tops with strawberry powder, or drizzle peanut butter over the chocolate. Toasted coconut sticks nicely and adds crunch.
How to Serve Chocolate Marshmallow Hearts
Serve these with coffee, hot cocoa, or a glass of cold milk. Add them to a dessert board with berries, pretzels, and shortbread for a sweet-salty spread. Pack pairs in mini cupcake liners and tuck them into gift boxes. For a fancy touch, finish with a pinch of flaky salt right before serving.
Storage Success
Store the coated hearts in an airtight container at cool room temperature. Separate layers with parchment to protect the finish. They hold for 5 to 7 days with the best texture on days 1 to 3. Freeze uncoated marshmallow hearts for up to 1 month, then thaw, dip, and decorate.

- Spread marshmallow evenly into prepared pan. Smooth top with a greased spatula. Let set at room temperature for 2 hours.
- Use a heart-shaped cookie cutter coated with powdered sugar to cut marshmallows into hearts. Dust sides lightly with additional powdered sugar.
- Melt chocolate and vegetable oil together (in a heatproof bowl over simmering water or in microwave). Stir until smooth.
- Dip each marshmallow heart in melted chocolate, letting excess drip off. Place on parchment paper to set. Repeat with remaining hearts.
- Allow the chocolate to set completely before serving or packaging.
