Pink Vanilla Key Lime Mallow Cones

These Pink Vanilla Key Lime Mallow Cones look just like soft serve ice cream! Make them for fun party favors, or for a sweet summer treat.

Pink Vanilla Key Lime Mallow Cones

Heaps of marshmallow and meringue were whipped up this weekend and then tinted in the softest pastels.

Sugar cones make great little vessels in which to carry fluffy homemade marshmallow. To make it a ringer for soft-serve, I piped it with a large French decorator tip. The colors and flavors were inspired by two paint swatches I’ve been toting around in my purse since late December. Maybe someday I’ll get to use those colors on a wall, but for now they look pretty good on dessert.

I find key lime treats so dreamy, and from my kitchen, they somehow they always end up with some sort of marshmallow accompaniment. (See here.) This recipe puts key lime flavor directly into the marshmallow!

Method to the madness.

Both recipes are adapted from fellow blogger Shauna Sever’s book Marshmallow Madness! (highly recommend!). I increased the gelatin ever-so-slightly to make sure the marshmallow batter would pipe well and hold up to a second layer stacked on top.  I couldn’t have asked for better results!

The key lime marshmallow flavor is so delicious, and together with the crunchy cone it reminds me of key lime pie. The pink vanilla layer swirled on top is a nice compliment, too. After the marshmallow is piped and set, the layers really stick together well, so I wouldn’t hesitate to make these for a kid’s party. There’s no chance of the marshmallow falling off/out of the cone, and it’s something that would be so easy for little hands to hold.

These were a delight to make, and pretty easy, too.  Just a note – like most marshmallow recipes, you’ll need a candy thermometer to make these.  If you need a large French star piping tip, you can buy one here.

You’ll be making two consecutive batches of marshmallow for these, so when you get finished piping the first layer in the cones, be prepared to wash up your saucepan, piping tip and batter bowl for the next layer. I tried dividing one batch of marshmallow into the two colors and flavors, but after piping the first color (lime), the second color had already begun to set up. An attempt at re-whipping only made the vanilla layer lax and un-pipeable. Two consecutive batches is the way to go, here. Small glasses make a nice holder in which to stand the cones upright while piping. I used 2 oz. cylinder dessert glasses.

Ingredients
 
 

Cones

  • 15 sugar cones
  • piping gel or clear corn syrup
  • white nonpareils

Key lime marshmallow

  • 5 teaspoons unflavored powdered gelatin
  • 1/4 cup key lime juice
  • 1/4 cup cold water
  • 1 cup sugar
  • 1/2 cup light corn syrup divided
  • 1/4 cup water
  • Pinch of salt
  • Green food color

Pink vanilla marshmallow

  • 5 teaspoons unflavored powdered gelatin
  • 1/2 cup cold water
  • 3/4 cup sugar
  • 1/2 cup light corn syrup divided
  • 1/4 cup water
  • Pinch of salt
  • 1/2 teaspoon clear vanilla extract
  • Pink food color

Instructions
 

Cones

  • Brush piping gel or clear corn syrup around the top edges of 15 ready made sugar cones. Place the nonpareils on a small plate and then roll the edge of a cone in the sprinkles. Repeat with remaining cones and leave to dry on parchment paper. Have the cones placed upright in glasses and ready to receive piped marshmallow.

Key Lime Marshmallow

  • Whisk together in a small bowl – gelatin, key lime juice and 1/4 cup cold water. Let set for 5 minutes until gelatin absorbs liquid.
  • In a saucepan with a candy thermometer inserted, combine sugar, 1/4 cup corn syrup, 1/4 cup water and salt. Place over high heat and bring to a boil. Meanwhile, pour the remaining 1/4 cup corn syrup in the bowl of a standing mixer fitted with the whisk attachment. Heat the gelatin in the microwave or on the stove-top until melted completely and pour into the mixing bowl with the corn syrup. Turn mixer on low and keep it stirring until the sugar syrup is ready.
  • When the syrup reaches 240F. slowly pour it into the mixer bowl. Increase the speed to medium and beat for 5 minutes, then increase to medium-high and beat 5 more minutes. Finally, increase to highest speed and beat 5 more minutes, until tripled in volume. Add food coloring and beat until incorporated. Immediately scoop marshmallow into the large piping bag – do not tarry here -and quickly pipe the mixture into the cones, swirling in a circular motion as you pipe.

  • When the syrup reaches 240F. slowly pour it into the mixer bowl. Increase the speed to medium and beat for 5 minutes, then increase to medium-high and beat 5 more minutes. Finally, increase to highest speed and beat 1-2 more minutes, add vanilla then beat again for 1-2 minutes. Mixture should be opaque and tripled in volume. Add food coloring and beat until incorporated. Immediately scoop marshmallow into the large piping bag – do not tarry here -and quickly pipe the mixture into the cones, swirling in a circular motion as you pipe.
  • Let cones stand upright in small glasses until set. Dust with marshmallow coating if desired (see notes for coating recipe).

Notes

Combine 3/4 cup confectioners’ sugar with 1/2 cup cornstarch and dust the cones with this mixture. This will take away any stickiness and makes them easy to bag in cellophane for party favors.

Would you please provide the weight equivalent for your 5 teaspoons of gelatin? I would love to see all recipes use weight instead of volume measurements… it's so much more accurate! Thank you so much!

Chef Beth – 5 teaspoons is about 3/4 oz.

Claudia – they are't mini, I used the standard size cones that you get at the grocery store.

Yummy! These look delicious and cute! They'd be perfect for a friends birthday- the only problem is that she's vegetarian. Is there any way I could substitute the gelatin?

Siriusyareader – There are vegetarian gelatins out there; some of the kosher varieties (not all). I think Hein may be one brand. I have a friend who is vegetarian and so I've bought some before for various projects around her birthday.

Would a simple honey and water solution work (in place of the sugar, water and corn syrup)? I try to avoid corn syrup and typically make a honey, gelatin and water version of marshmallow, was wondering how that would work out and in what measurements to get the right end product.

Hei, can I melt store bought marshmallows and use those? Would they return to their original consistency?

Hi Cristina!

No, I'm afraid that won't work. The marshmallow won't hold its shape after melted.

I’m not sure what you mean but dust the whole cone. Marshmallow and cone? I’m doing an all edible Christmas tree this year since we didn’t get to celebrate last year due to the pandemic. My 6 little granddaughters will love this
