Ingredients for brown rice flour mochi
Twelve ingredients transform into traditional mochi with modern vegan adaptations.
| Ingredient | Amount | Notes |
|---|---|---|
| Brown Rice Flour 🌾 | 2 cups | Gluten-free, finely milled preferred |
| Silken Tofu 🧈 | 1 package | 8 oz, soft variety |
| Extra-Firm Tofu 🧈 | 1 package | 14 oz, pressed for moisture |
| Granulated Sugar 🍯 | ¼ cup | Organic preferred for purity |
| Melted Butter Substitute 🫒 | ½ cup | Vegan butter or coconut oil |
| Red Bean Paste 🌱 | 1 cup | Store-bought or homemade |
| Black Sugar 🍬 | 2 tbsp | For coloring and sweetness |
| Kuzu Powder 🌿 | 1 tbsp | Kudzu starch for elasticity |
| Water 💧 | ½ cup | Room temperature preferred |
| Cornstarch 🌽 | 1 tbsp | For dusting work surface |
| Sesame Seeds 🌰 | 2 tbsp | Toasted for garnish |
| Matcha Powder 🍵 | 1 tsp | Optional for green mochi |
The brown rice flour is non-negotiable for that authentic, nutty flavor—Bob's Red Mill or Anthony's brands work best. Silken tofu provides moisture and structure, while extra-firm tofu adds body; both should be organic if possible for cleaner texture. The kuzu powder (kudzu starch) is the secret to elasticity—find it in Asian markets or online if your local store doesn't carry it. For the melted butter substitute, Miyoko's vegan butter or coconut oil both work perfectly, though coconut oil adds a subtle sweetness. Red bean paste can be store-bought (check for sugar content) or homemade with azuki beans.
No kuzu powder? A mix of cornstarch and tapioca starch at a 1:1 ratio mimics its properties, though texture won't be identical. Silken tofu unavailable? Substitute with 1 cup mashed sweet potato for moisture, but expect slightly denser mochi. Black sugar can be swapped for dark brown sugar, though it lacks the molasses depth. For matcha mochi, use culinary-grade matcha—Ippodo Tea or Jade Leaf brands are reliable. The cornstarch is purely functional; arrowroot powder works equally well for dusting. Sesame seeds can be omitted if nut-free is required, but toast them first—they add a satisfying crunch.
Store unfilled mochi dough in an airtight container with parchment paper between layers for up to 3 days in the fridge. Once filled, they keep for 2 days—best enjoyed fresh. For longer storage, freeze shaped mochi (unfilled) for 3 months; thaw at room temperature before filling. Filled mochi freezes beautifully too, but steam them briefly after thawing to restore moisture. Prevent sticking by dusting work surfaces generously with cornstarch—no flour allowed, or you'll lose that signature chew.
Why You'll Love This Recipe
- I use what I already have: brown rice flour (cheaper than glutinous rice flour), tofu (dollar store prices), and sugar that lasts forever. Plus, leftovers freeze like a dream—just steam again for fresh mochi any day. Zero waste, maximum flavor.
- No-Fuss Mixture: I swear by this recipe because it’s just three bowls—flour, tofu, sugar—and a quick steam. No rolling dough, no fussing with rice flour ratios like other mochi recipes. The silken tofu blends into a silky batter that practically steams itself into perfect little pockets.
- Chewy Crisp Edge: Between us, the texture is ridiculously satisfying—the outside gets that delicate crisp from the butter substitute, while the inside stays pillowy thanks to the brown rice flour. It’s the kind of mochi that makes you pause mid-bite, like discovering a secret weapon in your pantry.
- Weeknight Crowd-Pleaser: Honestly, this is my go-to for potlucks or lazy Sundays. The extra-firm tofu holds shape when stuffed (think sweet red bean paste or Nutella), and it reheats beautifully. Even my picky nephew grabs seconds—proof it’s not just a fancy dessert.
Step-by-step instructions for brown rice flour mochi
Master this gluten-free mochi technique for perfectly chewy, pillowy results every time.
Prepare the Dough Base
In a food processor fitted with the metal blade, combine the 2 cups brown rice flour, 1 package silken tofu (drained if packaged in water), 0.25 cup granulated sugar, 1 tbsp kuzu powder, and 1 tbsp cornstarch. Pulse until the mixture resembles fine crumbs with no large flour chunks remaining. This texture is crucial for achieving that signature mochi chewiness.
Transfer the flour mixture to a large mixing bowl. Add the 1 package extra-firm tofu (pressed and crumbled), 0.5 cup melted butter substitute, and 0.5 cup water. Using clean hands or a rubber spatula, knead the dough vigorously for 5-7 minutes until it becomes smooth, elastic, and slightly sticky. The dough should pull away cleanly from the bowl and not feel gritty. If it's too dry, add 1 tsp water at a time until pliable.
Divide and Flavor the Dough
Divide the dough into 12 equal portions (about 2 oz each) and roll each into a 1-inch diameter ball. For standard mochi, set these aside. For matcha mochi, mix 1 tsp matcha powder with 1 tbsp water to form a paste, then gently fold this into 6 of the dough balls until evenly distributed. The matcha should create vibrant green streaks throughout the dough.
For red bean mochi, gently press 1 tbsp red bean paste into the center of 6 dough balls, then seal by pinching the edges together. The paste should be fully encased without leaking. If working with black sugar mochi, mix 2 tbsp black sugar with 1 tsp water, then brush this mixture over 6 dough balls before sealing. The sugar will caramelize slightly during cooking, adding depth of flavor.
Shape and Steam the Mochi
Lightly dust your work surface with cornstarch and roll each dough ball between your palms to form a 3-inch long oval shape, about ½-inch thick. The edges should be slightly tapered for that classic mochi silhouette. Place the shaped mochi on a parchment-lined baking sheet, leaving 1 inch between each piece to prevent sticking.
Bring a steamer filled with 2 inches of water to a rolling boil. Place the mochi on the steamer rack, cover, and steam for 12-15 minutes until the edges turn slightly translucent and the centers feel firm to the touch. The steaming time is critical—understeamed mochi will be gummy, while oversteamed mochi becomes dense. Test doneness by piercing one mochi with a skewer; it should come out clean with no raw dough.
Finish and Garnish
Remove the steamed mochi from the steamer and let them cool on the rack for 5 minutes. While still warm, roll each mochi in toasted sesame seeds until fully coated. The seeds should adhere evenly, creating a textural contrast against the chewy interior. For extra shine, lightly brush the tops with a melted butter substitute mixed with 1 tsp water using a pastry brush.
Serve immediately while still warm for the perfect balance of chewiness and softness. These mochi will keep at room temperature for 2 days in an airtight container, though they're best enjoyed fresh. The gluten-free brown rice flour delivers that authentic mochi texture without the wheat, making this recipe both inclusive and delicious.
Pro Tips For Making Brown Rice Flour Mochi
- STEAM DON’T BOIL: The second the mochi hits the pot, lower the heat to a gentle simmer—not a rolling boil. I learned this after watching my first batch turn into gluey, uneven blobs. Brown rice flour thickens fast; you’re aiming for a slow, even cook that keeps the texture smooth, not gummy. If it looks too thick too soon, add 1-2 tablespoons of water, but keep that heat low.
- GRIND TOFU FINE: Skip the food processor for the extra-firm tofu—your hands (or a potato masher) work better. The goal is a paste with no visible chunks, or you’ll get weird textures in every bite. For the silken tofu, though, blend it until it’s completely smooth—no streaks, or your mochi will taste like it’s fighting itself.
- WEIGH THE FLOUR: That bag of brown rice flour? It’s deceiving. Scoop it straight from the bag, and you’ll end up with dry, crumbly mochi. Instead, use a kitchen scale for precision—about 2 cups equals roughly 200 grams. Too much flour, and your mochi turns into a dense brick; too little, and it falls apart when you try to shape it.
- CHILL THE MIX: Let the batter sit in the fridge for 10 minutes before shaping. I know, it’s tempting to dive right in, but this step makes all the difference—especially in humid kitchens. Cold batter holds its form better, so your mochi stays together when you roll it. Plus, it’s easier to handle without sticking to your fingers. (Yes, even if you’re impatient like me.)
Storing and reheating this dish
Fridge Storage Tips
Store freshly made mochi in an airtight container with parchment paper between layers to prevent sticking. They’ll keep for 2 days at 40°F or below, though the texture softens slightly after the first day.
The brown rice flour base helps preserve freshness better than traditional wheat-based mochi. For filled varieties, place them seam-side down to maintain shape. 💫
Freezing Unfilled Dough
For longer storage, freeze the unfilled dough balls (about 2 oz each) on a floured tray before transferring to a freezer bag. Thaw at room temperature for 30 minutes before shaping and steaming—no need to add extra water.
Frozen dough keeps for 3 months, making this a great make-ahead option for busy days. Just steam 1-2 minutes longer after thawing to restore moisture.
Reheating Filled Mochi
Filled mochi reheats best in a steamer for 3-4 minutes to restore chewiness. Place them on the rack 1 inch apart to avoid sogginess. For microwave reheating, cover with a damp paper towel and heat on 50% power for 15 seconds—this prevents drying.
Avoid the microwave for more than 10 seconds at a time, or the texture becomes gummy. 🔥
Reviving Dried Mochi
If your mochi loses moisture after storage, steam for 2 minutes to revive. For extra shine, brush with a melted butter substitute (like Miyoko’s) mixed with 1 tsp water after reheating.
The kuzu powder helps them bounce back better than traditional mochi, but they’ll never be as chewy as fresh. Keep a small container of cornstarch handy to dust between layers if storing again.
Preventing Sticking
Cornstarch is your best friend here—dust every surface (hands, board, steamer rack) generously. Avoid flour, as it alters the texture. For extra insurance, line your steamer basket with parchment paper cut to size.
If mochi sticks during shaping, gently roll it in more cornstarch before steaming. The sesame seed coating also adds a natural barrier against sticking when stored. ✨

Frequently asked questions
Why does my brown rice flour mochi turn out gummy instead of chewy?
The texture depends on precise hydration and steaming time. If your mochi feels gummy, you likely oversteamed it—aim for 12-15 minutes until edges are translucent but centers stay firm. For extra chewiness, ensure your dough is properly kneaded (no dry spots) and use kuzu powder (kudzu starch) as it’s key for elasticity. If you skipped it, substitute with a 1:1 mix of cornstarch and tapioca starch.
Can I make this mochi without a food processor?
Mix the dry ingredients by hand in a large bowl, then use a fork to break up any lumps. For the dough, knead vigorously with your hands for 7-10 minutes—the extra effort ensures smooth texture. If the dough feels too dry, add 1 tsp water at a time until pliable. The key is patience; traditional mochi-making is all about handwork!
What’s the best filling for brown rice flour mochi?
Classic options include red bean paste (anko) for sweetness, or black sugar syrup for caramelized depth. For modern twists, try mango purée, chocolate ganache, or even matcha cream. The filling should be 1 tbsp per mochi—too much causes leaks during steaming. Seal edges tightly by pinching with wet fingers to prevent filling from escaping.
How do I fix dough that’s too sticky or too dry?
If the dough is too sticky, dust your hands and surface with cornstarch and knead for 2 more minutes—the moisture will distribute. For dry dough, add 1 tsp water at a time and knead until smooth. Pro tip: Cover the dough with a damp towel while working to maintain moisture. The ideal dough should feel slightly tacky but not gluey, and pull away cleanly from your fingers.
Can I bake these mochi instead of steaming?
Baking isn’t recommended—it’ll dry out the mochi and lose that signature chewy texture. If you must, bake at 350°F for 8-10 minutes*, but expect a denser result. Steaming (12-15 minutes) is the only method that mimics traditional mochi’s pillowy-yet-firm bite. For extra shine after steaming, brush with a melted butter substitute mixed with 1 tsp water while warm.
