Whether you call them Mallomars, whippets, krembos, Viva Puffs, mallowpuffs, pinwheels, or chocolate tea cakes, chocolate-covered marshmallow cookies are beloved childhood treats around the world. Today I’m sharing a homemade Neapolitan version, which fuses vanilla shortbread, strawberry marshmallow, and dark chocolate coating. These cookies are a blast to make and sure to delight the entire family!
These neapolitan mallomars are a little bit of a project, but none of the elements are too difficult. To divide the work I like to bake the shortbread bases one day, then make the marshmallow and dip the cookies in chocolate the next. However, you can make these in one afternoon — choose a time when you are relaxed and ready to have fun in the kitchen!
To temper or not to temper
Recently over on Instagram I asked how people felt about tempering chocolate. Most people said they’d rather not, with “I’ve never done it before” or “It takes too long” being the main reasons. I understand that working with chocolate can seem intimidating, especially if you don’t do it often — I’m definitely no expert!
But if unfamiliarity is the only thing holding you back, I encourage you to give tempering chocolate a shot for this recipe. It’s a fantastic skill to have, and nothing can truly replace the shine and snap of well-tempered chocolate. I used the cocoa butter silk tempering method this time (yes, I made my own silk because we’re still stay-at-home over here so why not). If you have the time and tools for this (sous vide machine, cocoa butter) give it a shot — I was really happy with how easy it was! But if not, this article on chocolate tempering from Sugar Geek Show walks you through a few options. Choose whichever makes the most sense for you!
However, if you’d really rather not temper you can cover the cookies with a mixture of chocolate and coconut oil, which will set nice and snappy in the fridge. If you go this route the chocolate shell will look a little less pristine and you will need to store the cookies in the fridge, but the end product will still taste wonderful.
- Freeze-dried strawberries are the key ingredient to making a vibrantly fruity marshmallow. I buy mine online, but check your grocery store or local specialty food store as well. Don’t grind the strawberries until you’re ready to make the marshmallow — the strawberry powder tends to clump with exposure to air. If you can’t find freeze-dried strawberries, you can leave it out for a plain marshmallow center.
- Before dipping the cookies, I like to pour the melted chocolate into a tall, narrow vessel (like a deli quart container). Choose something microwave-safe so that if the chocolate starts to cool and thicken too much, you can reheat it gently (5 second bursts in the microwave, stirring well after each!).
Makes about 30 cookies
For the vanilla shortbread:
- 150g unsalted butter, at room temperature
- 50g icing (powdered) sugar
- Scant 3/4 tsp kosher salt
- Seeds from one vanilla bean (optional)
- 1 1/2 tsp pure vanilla extract
- 165g all-purpose flour
For the strawberry marshmallow:
- 45g freeze-dried strawberries
- 14g powdered gelatin
- 76g water (for blooming the gelatin)
- 1 tsp pure vanilla extract
- 76g water (for the sugar syrup)
- 95g corn syrup
- 227g granulated sugar
- 1/4 tsp kosher salt
For the chocolate coating:
- 340g good-quality semisweet chocolate (I used Callebaut 54.5%), tempered
- 34g refined coconut oil (optional, if not tempering the chocolate)
For the vanilla shortbread:
Make the shortbread dough: In the bowl of a stand mixer fitted with the paddle attachment (or using a handheld mixer), combine the butter, icing sugar, vanilla bean seeds (if using), and salt. Mix on low to combine, then increase the speed to medium and beat until smooth and well-combined, about 2 to 3 minutes. Scrape down the paddle and sides of the bowl. Add the vanilla extract and beat well to combine. Turn the mixer down to low and add the flour, mixing just to combine. Use a flexible spatula to fold from the bottom of the bowl to make sure everything is well-mixed and there are no pockets of unincorporated flour. If the dough is very soft and sticky, cover and chill for about 10 minutes before proceeding.
Roll and chill the dough: Transfer dough to a piece of parchment paper and pat into a square about 1-inch (2.5-cm) thick. Place another piece of parchment on top and roll dough to about ¼-inch (6-mm) thick, lifting the top piece of parchment occasionally to avoid creases in the dough. Slide dough onto a baking sheet (still sandwiched between pieces of parchment). Refrigerate until firm, at least 30 minutes or up to 2 days.
Cut and bake the shortbread cookies: When ready to bake, preheat the oven to 350F with a rack in the middle. Line a large cookie sheet with parchment paper (I reuse one of the sheets sandwiching the cookie dough). Use a 1 3/4″ round cookie cutter to cut circles, gathering and rerolling the scraps until the dough is used up. Place cookies on the prepared sheet, spacing about 1″ apart (they won’t spread much).
Bake cookies until set and the edges are lightly golden, about 15 minutes. Cool completely on a wire rack before assembling.
For the strawberry marshmallow:
Make the freeze-dried strawberry powder and prep your tools: Place the freeze-dried strawberries in the bowl of a food processor. Pulse until they form a fine powder. Set aside. Fit a piping bag with a 1/2″ round tip. Arrange all the cooled shortbread cookies on a parchment-lined sheet pan. (Once the marshmallow is whipped, you must immediately pipe it onto the cookies before it starts to set.)
Bloom the gelatin: In a small, wide bowl, mix the gelatin with 76g cool water and the vanilla extract. Stir to combine, making sure all the gelatin is saturated. Leave to bloom while you prepare the sugar syrup.
Cook the sugar syrup: In a medium (3-3.5L) heavy-bottomed saucepan, combine the remaining 76g water, corn syrup, sugar, and salt. Stir to combine. Place over medium heat. Stir occasionally with a heat-proof spatula or fork until the mixture starts bubbling, then stop stirring (stirring a boiling sugar syrup can encourage crystallization). Clip on a digital thermometer and continue cooking the syrup until it reaches 250F.
Cool the syrup: Once the syrup reaches temperature, carefully pour the hot syrup into the bowl of a stand mixer, using a flexible, heat-resistant spatula to scrape the pot. Let the syrup cool until it registers 212F on a digital thermometer, about 4-5 minutes.
Whip the marshmallow: Once the syrup has cooled to 212F, scrape the bloomed gelatin into the bowl. Carefully transfer the bowl to the mixer fitted with the whisk attachment. Whisk on medium low until the gelatin has melted, then increase the speed to medium-high and whisk until the mixture is fluffy, thick, and roughly tripled in volume and the mixer bowl has cooled to room temperature, about 10 minutes. Turn off the mixer and add the strawberry powder. Mix for about 15-30 seconds, or until powder is evenly mixed in. Grease a flexible spatula or plastic bowl scraper and scrape the marshmallow into the prepared piping bag.
Pipe the marshmallow: To pipe the marshmallow, hold your piping bag at a 90-degree angle about half an inch above a cookie. Squeeze until a mound of marshmallow covers the entire base, then slowly pull up as you stop squeezing. Repeat with the remaining cookies. You can leave the marshmallows with little peaks, or use a damp finger to flatten them down. Let set at room temperature, uncovered, until set and no longer sticky — about 45-60 minutes. (If you have any remaining marshmallow, pipe it onto a piece of parchment and let it set overnight; then cut into cubes and toss with equal parts cornstarch and icing sugar. Store in an airtight container.)
For the chocolate coating:
Prepare the chocolate: When you’re ready to dip the cookies, temper chocolate using your preferred method. Alternatively, chop the chocolate into small, even pieces. Heat the chopped chocolate and coconut oil together in 20-second bursts in the microwave, stirring well in between, until just melted. Be careful not to overheat.
Dip the cookies: Place a piece of parchment under a large wire cooling rack. Holding a cookie by the base, dunk into the chocolate to completely coat marshmallow. Hold upside-down for a few seconds to let any excess chocolate drip off back into the bowl, then place cookie-side-down on the wire rack. Repeat with remaining cookies. If using tempered chocolate, let cookies set at cool room temperature for about an hour before enjoying. If using chocolate-coconut oil coating, refrigerate for about 15 minutes until set. Store leftover cookies in an airtight container for at least a week. Tempered chocolate cookies can be kept at room temperature; chocolate-coconut oil-coated cookies should be stored in the refrigerator.
