How to Make Your Own Mochi Ice Cream (& Spare Yourself from Trader Joe's)

August 19, 2016

Soft mochi—smooth and pillowy and cotton ball-light—needn't be messed with. But if you had to—let's say it's August (yes) and a billion degrees outside (yes) and you wish your big toe could be submerged in an ice bath at all times (yes, yes, yes)—you could combine it with ice cream. And not just combine it with ice cream, but wrap it around the scoops to make a handheld and highly adorable dessert.

You know the kind: You buy them at Trader Joe's or order them at sushi restaurants or from fancy websites (?).

With only two component parts (mochi, ice cream), they're simple—if not necessarily easy—to make at home. (And personally, I do everything in my power to avoid the New York City Trader Joe's lines.)

Shop the Story

Because the mochi needs to engulf the ice cream balls, you'll have to contort it in a slightly unnatural way, manipulating (and warming, and melting) the ingredients much more than for a typical ice cream sandwich. In summer's heat, it's a bit of a masochistic pursuit—but not an impossible one. It's fun! And you can choose whatever combination of mochi (matcha, black sesame, vanilla, mint) and ice cream (cookies and cream, strawberry, chocolate) you want.

You'll need to track down sweet glutinous rice flour and your favorite store-bought ice cream (it's easier to work with than homemade), but once you've got those, you're good to go.

These tips will make the process easier:

  • You'll need to scoop and refreeze the ice cream well before assembly. Portion them into a mini muffin tin or an egg carton lined with plastic wrap.
  • You want your mochi to be cool but also very fresh. As mochi sits, it becomes drier and less elastic, which means it'll be more prone to tearing as you try to stretch it around the little ice cream scoop. Since mochi-making takes only about 30 minutes from start to finish, I recommend starting that process when the individual ice cream balls are already frozen solid.

  • As you're making the mochi, be generous with the cornstarch to avoid stickiness. You can always dust it off later! I also recommend sifting the cornstarch to avoid big clumps.
  • Plastic wrap is here to help. Place each mochi round on a generous piece of plastic wrap, then use the excess to help gather and smush the mochi around the ice cream: You'll be able to belt it all together and then shove it in the freezer—all ice cream leaks will be contained until they refreeze.

  • And plastic gloves will help, too: They'll protect the ice cream from the warmth of your hands.

  • If possible, work with one ball of ice cream at a time (and in close proximity to the freezer).
  • Let your mochi soften a bit at room temp before attempting to slice or bite or serve to friends. The mochi layer needs some time to relax back into its naturally soft state.

Would you rather eat mochi ice cream or just plain mochi? And what's your favorite flavor combination? Tell us in the comments!

I love any form of Mochi, broiled so it's crispy and gooey inside, crispy baked in a waffle iron or as a sweet with bean centers or ice cream.

This looks like fun! I doubt if I will find the rice flour near me, but I bet I could make it from grinding up sushi rice into flour in the blender. I'll report back!

I've filled my mochi with matcha, lychee and avocado ice creams. All are delectable!

This is one of my favorite things in the world to eat. Sarah, if you tell me I can make it at home I'm going to take you at your word!

It's not SUPER EASY—but you can do it! (If you're at the level where you can dip entire ice cream sandwiches in melted chocolate, you can make mochi ice cream.)

these are a pain in the butt to make. somehow mine still melt allll over the place when i try to combine the mochi and ice cream, no matter how cool the mochi is, how frozen the ice cream is, how fast i work! i'll have to try the gloves and see if those help.
