Ingredients You’ll Need
The magic of this Mochi Stuffed Chocolate Cake comes from a few carefully chosen ingredients that balance texture, flavor, and richness. Each component plays its role perfectly—from the soft, chewy mochi center to the moist, chocolatey cake exterior. Don’t worry, these ingredients are straightforward and simple, making your baking adventure smooth and enjoyable.
- Chocolate cake batter: Use your favorite homemade or boxed mix to provide a rich, chocolatey base that’s moist and tender.
- Glutinous rice flour: This key ingredient is what gives mochi its signature chewiness and stretch.
- Sugar: Sweetens the mochi dough for a delicate balance against the chocolate.
- Milk: Adds moisture to the mochi dough, making it soft and pliable for easy shaping.
How to Make Mochi Stuffed Chocolate Cake
Step 1: Prepare the Mochi Dough
Start by mixing glutinous rice flour with sugar and milk to create a smooth, pliant dough. The key here is to achieve a consistency that is soft but not too sticky, so it holds its shape well when you form it into discs. This dough will be the delightful center of your cake, so take a moment to feel how stretchy it is—this is what makes the mochi so special.
Step 2: Shape Mochi Discs
Divide the mochi dough into even portions and flatten each into small discs. These discs will nestle inside the cake batter and expand slightly when baked. Working quickly but carefully at this stage is important to keep the mochi moist and workable.
Step 3: Pour Half of the Cake Batter
Prepare your chocolate cake batter according to your recipe or package instructions, then pour half of it into your greased baking pan, smoothing the surface evenly. This layer will cradle the mochi surprises, so make sure the batter is spread gently but thoroughly.
Step 4: Add Mochi Center and Cover with Remaining Batter
Place the mochi discs evenly spaced on top of the first batter layer. Then, generously cover them with the remaining chocolate batter, hiding the stretchy centers from view. This ensures every slice will have that chewy-moist contrast baked right in.
Step 5: Bake Until Set but Soft Inside
Bake the cake in a preheated oven for about 35 minutes, or until the cake appears set and a toothpick inserted in the cake comes out mostly clean. The cake should be moist but hold its shape, while the mochi inside remains soft and stretchily tender. Keep an eye on the timing to avoid overbaking the delicate mochi center.
Step 6: Slice and Enjoy the Stretch
Once cooled slightly, slice the cake to reveal the irresistible gooey mochi inside. As you lift each piece, watch the stretchy mochi pull away — it’s beyond satisfying and sure to wow anyone lucky enough to dig in first!
How to Serve Mochi Stuffed Chocolate Cake

Garnishes
Simple garnishes like a dusting of powdered sugar or a drizzle of dark chocolate ganache elevate this Mochi Stuffed Chocolate Cake beautifully. Fresh berries or a sprinkling of toasted sesame seeds add a light, contrasting flavor and visual appeal.
Side Dishes
Pair this cake with a scoop of vanilla ice cream or a dollop of whipped cream to complement the chewy mochi and rich chocolate layers. Green tea or coffee provide perfect beverage choices that balance sweetness and refresh the palate.
Creative Ways to Present
Try serving this Mochi Stuffed Chocolate Cake warm for that ultimate melty stretch, or chill slices briefly for a firmer bite. You can also cut the cake into mini squares for bite-sized treats at a party, making the stretchy mochi center a delightful surprise in every piece.
Make Ahead and Storage
Storing Leftovers
Store any leftover Mochi Stuffed Chocolate Cake in an airtight container at room temperature for up to two days. If you prefer it refrigerated, it can last up to four days, but the mochi may firm up slightly.
Freezing
This cake freezes well, which is great for making ahead. Wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag or container. Frozen, it will keep for up to one month without losing its delightful texture.
Reheating
To enjoy the stretchy mochi effect after storage or freezing, warm slices gently in the microwave for 20-30 seconds or until soft and pliable. This brings the mochi back to life while keeping the chocolate cake tender and inviting.
FAQs
Can I use regular rice flour instead of glutinous rice flour?
Regular rice flour won’t give you the same stretchy, chewy texture that glutinous rice flour provides, so it’s important to use the glutinous variety for an authentic mochi center.
Is this Mochi Stuffed Chocolate Cake gluten-free?
The mochi itself is gluten-free since it’s made from glutinous rice flour, which contains no gluten despite the name. However, make sure your chocolate cake batter is gluten-free if you need the entire dessert to meet those dietary needs.
Can I make the mochi disks ahead of time?
You can prepare the mochi dough and shape the disks a few hours before baking, but keep them covered tightly with plastic wrap to prevent drying out until you’re ready to assemble the cake.
What if I don’t have a boxed chocolate cake mix?
Feel free to use a homemade chocolate cake batter recipe you love! Just ensure the batter is moist and not too dense, which will allow the mochi center to stay soft and stretchy.
Why does the mochi center stay stretchy after baking?
Mochi’s unique texture comes from glutinous rice flour, which retains chewiness and stretchiness even when heated. Baking encases the mochi in cake, allowing it to soften without melting or becoming tough.
