Homemade Sesame Mochi: A Chewy, Nutty Treat with Purple Sweet Potato & Mung Bean Fillings

Okay, let’s be real—store-bought mochi can be a hit or miss. I’ve had those sad, powdery peanut mochi from the supermarket that leave your mouth feeling like a dust storm? No thanks. But when I stumbled on this homemade sesame mochi recipe with purple sweet potato and mung bean fillings? Game. Changer. This isn’t just any mochi—it’s chewy, fragrant, and so satisfying you’ll want to make a double batch (trust me, I did).

Why This Sesame Mochi Beats Store-Bought (Spoiler: It’s All About the Texture)

Let’s get one thing straight: store-bought mochi often relies on too much dry rice flour coating to prevent sticking. That means every bite feels like you’re chewing on a cloud of powder—no thanks. This homemade version? We skip the excess flour and roll the mochi in toasted white sesame seeds instead. The sesame adds a nutty crunch that pairs perfectly with the chewy mochi skin and sweet fillings. Plus, we’re using fresh purple sweet potato and mung bean fillings (no weird preservatives here!)—hello, flavor explosion.

What Makes This Mochi Recipe Stand Out?

• No fancy equipment needed (just a microwave—yes, really!)
• Chewy, non-sticky mochi skin that doesn’t turn rock-hard after a day
• Two delicious fillings: creamy mung bean and earthy purple sweet potato
• Toasted sesame seeds for extra flavor (pro tip: toast them yourself—game changer)

Let’s Gather Our Ingredients (No Weird Stuff, Promise)

You don’t need a trip to a specialty Asian market for this—most ingredients are right in your pantry or local grocery store. Here’s what you’ll need:

For the Mochi Skin:

• 40g rice flour (not the same as all-purpose—stick to rice flour!)
• 50g glutinous rice flour (this is non-negotiable for that chewy texture)
• 30g cornstarch (or swap for tapioca starch if you prefer a softer bite)
• 30g granulated sugar (adjust to taste—we like a subtle sweetness)
• 180ml whole milk (dairy or plant-based works, but whole milk gives a richer texture)
• 10g vegetable oil (neutral oil like canola or sunflower—avocado oil works too)

For the Fillings:

• 100g mung bean paste (store-bought is fine, but homemade is even better!)
• 100g purple sweet potato paste (roast your own sweet potato, mash it, and mix with a little sugar for the best flavor)

For Rolling:

• 1/4 cup white sesame seeds (toasted—trust me, this step makes all the difference)

Step-by-Step: How to Make Perfect Sesame Mochi (Even If You’re a Beginner)

Okay, let’s get cooking! This recipe is super straightforward—no complicated techniques here. Just follow along, and you’ll have chewy, delicious mochi in under an hour.

Step 1: Prep Your Ingredients (No Cutting Corners Here)

First, let’s get everything measured out. It’s easy to rush this step, but trust me—precision matters here. Lay out your rice flour, glutinous rice flour, cornstarch, sugar, milk, and oil. No one wants a lumpy mochi skin, so measuring correctly is key.

Step 2: Mix the Wet Ingredients (Sugar + Milk = Happy Base)

Start by pouring the whole milk into a microwave-safe bowl. Add the granulated sugar and stir until it’s fully dissolved. I like to use a whisk here to make sure there are no sugar clumps at the bottom—those can ruin the texture later!

Step 3: Add the Dry Flours (Slow and Steady Wins the Race)

Next, add the rice flour, glutinous rice flour, and cornstarch to the milk-sugar mixture. Stir slowly with a whisk—this will help prevent lumps from forming. If you see any small clumps, don’t panic! We’ll fix those in the next step.

Step 4: Stir Until Smooth (No Lumps Allowed!)

Keep stirring until the mixture is completely smooth—think of it like a thick, runny batter. If there are still a few lumps, you can strain it through a fine-mesh sieve (pro tip: this makes the mochi skin extra silky!). I usually skip the sieve if the mixture looks smooth, but straining is a good extra step for perfectionists.

Step 5: Add the Oil (This Prevents Sticking—Thank Me Later)

Now, pour in the vegetable oil and stir it into the batter. The oil will help the mochi stay soft and non-sticky after it’s cooked. Don’t skip this step—trust me, you don’t want a rock-hard mochi that sticks to your teeth.

Step 6: Cover and Microwave (The Magic Happens Here)

Cover the bowl tightly with plastic wrap (I like to poke a few small holes in the top to let steam escape—no microwave explosions!). Pop it into the microwave and cook on high for 3 minutes. Wait, that’s it? Yep! The microwave will cook the batter into a soft, chewy mochi skin.

Step 7: Check for Doneness (No Wet Spots Allowed)

After 3 minutes, carefully remove the bowl from the microwave (it will be hot!). Use a fork or chopsticks to stir the mochi—if it’s smooth and there are no wet, powdery spots, it’s done! If there are still a few wet spots, microwave it for another 30 seconds and stir again.

Prep the Fillings (Creamy + Earthy = Perfect Pair)

While the mochi skin cools a little (it’s still hot, so be careful!), let’s prep the fillings. I love using mung bean paste and purple sweet potato paste because they’re sweet but not overly so—they let the mochi and sesame shine.

Step 8: Roll Mung Bean Paste into Balls

Take the mung bean paste and divide it into 5 equal portions—each should be about 20g. Roll each portion into a smooth ball. If the paste is too sticky, dust your hands with a little glutinous rice flour. Set these aside on a plate.

Step 9: Roll Purple Sweet Potato Paste into Balls

Do the same with the purple sweet potato paste—divide it into 5 equal 20g portions and roll into balls. I love the vibrant purple color of these—they look so pretty next to the green mung bean balls!

Assemble the Mochi (Let’s Wrap This Up!)

Now, the fun part: assembling the mochi! The mochi skin is still warm, which makes it easier to work with. If it cools down too much, just microwave it for 10 seconds to soften it up.

Step 10: Divide the Mochi Skin into Portions

Take the warm mochi skin and divide it into 10 equal portions—each should be about 30g. Roll each portion into a smooth ball. I like to dust my hands with a little glutinous rice flour here to prevent sticking (but be careful not to use too much—you don’t want the mochi to be dry).

Step 11: Wrap the Mung Bean Filling

Take one mochi ball and flatten it into a small disc (about 3 inches wide). Place a mung bean ball in the center of the disc. Now, use your fingers to gently wrap the mochi around the filling—like you’re making a tiny dumpling. Pinch the edges together tightly to seal (no filling leaking out allowed!). Roll the mochi into a smooth ball (or a little cylinder, if you prefer—we’ll do that next).

Step 12: Wrap the Purple Sweet Potato Filling

Repeat the same process with the purple sweet potato balls. Flatten a mochi disc, add the filling, wrap, and seal. You’ll end up with 5 mung bean mochi and 5 purple sweet potato mochi—perfect for sharing (or not sharing, no judgment here).

Step 13: Shape the Mochi (Cylinders Are Cooler Than Balls, Fight Me)

Instead of leaving the mochi as balls, I like to gently roll them into small cylinders. They look fancier, and they’re easier to dip in sesame seeds. Just roll each mochi between your palms until it’s a smooth cylinder—about 2 inches long and 1 inch wide.

Step 14: Dip in Toasted Sesame Seeds (The Final Touch)

Now, let’s add the star of the show: toasted white sesame seeds! First, toast the sesame seeds in a dry pan over medium heat for 2-3 minutes—stir constantly so they don’t burn. You’ll know they’re done when they smell nutty and turn a light golden color. Let them cool for a minute, then pour them into a shallow dish.

Take each mochi cylinder and roll it in the toasted sesame seeds until it’s fully coated. Press gently to make sure the seeds stick—you don’t want them falling off when you take a bite!

My Honest Thoughts (Spoiler: I’m Obsessed)

Okay, let’s talk about the taste. When I took my first bite of this sesame mochi? Wow. The mochi skin is chewy but not tough—just the right amount of give. The toasted sesame seeds add a nutty crunch that pairs perfectly with the sweet fillings. The mung bean filling is creamy and slightly sweet, while the purple sweet potato filling is earthy and has a hint of natural sweetness. It’s not too sweet (thank goodness—no sugar crash here!), and the texture combination is just *chef’s kiss*.

I made this for a small gathering last weekend, and everyone went crazy for it. My friend who hates store-bought mochi said, “This is the best mochi I’ve ever had—can I take the recipe home?” (Spoiler: I gave it to her.) My roommate ate 3 in one sitting and asked when I was making more. Let’s just say this recipe is a keeper.

Pro Tips to Make Your Mochi Even Better (Trust Me, These Work)

I’ve made this recipe a few times now, so I’ve picked up a few tricks to make it even better. Here are my top tips:

1. Toast the Sesame Seeds (Don’t Skip This!)

Toasted sesame seeds have a deep, nutty flavor that raw sesame seeds just can’t match. It takes 2 minutes, and it makes a world of difference. Trust me—your taste buds will thank you.

2. Strain the Batter for Silky-Smooth Mochi

If you want the mochi skin to be extra silky (like the ones you get at fancy bakeries), strain the batter through a fine-mesh sieve before microwaving. It takes a little extra time, but the result is worth it.

3. Use Homemade Fillings (If You Have Time)

Store-bought fillings are fine, but homemade fillings taste way better. For mung bean paste: boil mung beans until soft, mash them, and mix with a little sugar and oil. For purple sweet potato paste: roast a purple sweet potato until tender, mash it, and mix with a little sugar. It’s easy, and the flavor is 10x better.

4. Store Mochi Properly (To Keep It Chewy)

Mochi can dry out quickly, so store it in an airtight container at room temperature for up to 2 days. If you want to keep it longer, freeze it—just let it thaw at room temperature for 10 minutes before eating. It will still be chewy and delicious!

Final Thoughts (I’m Already Planning My Next Batch)

Making homemade sesame mochi was such a fun experience—even for someone like me who’s not a pro baker. The recipe is straightforward, the ingredients are easy to find, and the result is a delicious treat that’s way better than anything you can buy at the store. I’m already planning my next batch—maybe I’ll try adding matcha powder to the mochi skin for a green tea twist? Or swap the fillings for red bean paste? The possibilities are endless!
