Bánh Khoai Mì Nướng, Vietnamese cassava cake, is chewy, coconutty, and slightly crisp on the outside.

It’s a simple, nostalgic treat that takes me straight back to cozy afternoons in my grandma’s kitchen.

Bánh Khoai Mì Nướng (Vietnamese Cassava Cake)

Bánh Khoai Mì Nướng is one of those desserts that instantly brings me back home to the South.

Down there, especially in the Mekong Delta, people have a way of turning simple, local ingredients into the most heartwarming treats — coconut, lady finger bananas, pandan leaves, and cassava.

This cassava cake is pure comfort if you’re a coconut lover. If you’re into buttery, chewy sweets like Butter Mochi, I’m pretty sure this one will steal your heart too.

Traditionally, making Bánh Khoai Mì Nướng meant a full-on workout — peeling, grating, and squeezing fresh cassava by hand.

That’s why frozen grated cassava is a lifesaver — it tastes just as good, skips the hard labor, and still gives you all that sweet, coconutty goodness.

What is Cassava?

Cassava — or khoai mì as we call it in Vietnam — is one of those humble roots that show up everywhere, from family kitchens to street food stalls.

You might also hear it called “yuca” or “manioc.” It’s the very root that gives us tapioca starch, the magic behind chewy boba pearls, taro balls, and so many Asian desserts we love.

Just one small but important note: cassava should never be eaten raw. It naturally contains compounds that can be toxic if not cooked properly. But don’t worry — once it’s soaked and cooked through, it turns into something soft, cozy, and deeply satisfying.

If you’re curious about more staples like this, I’ve even written a full post about the most common Vietnamese vegetables you’ll run into — and how we use them in everyday cooking.

Ingredients

Ingredients for Vietnamese Cassava Cake, including Frozen Grated Cassava, Coconut Milk, Sweetened Condensed Milk, Tapioca Starch, Melted Butter, Vanilla Sugar, Shredded Coconut Meat, Salt
  • Frozen Grated Cassava – This is the heart of the recipe. You can find it in most Asian or Mexican markets, and it saves you all the peeling and grating that fresh cassava usually requires.
  • Sweetened Condensed Milk – Thick, creamy, and irresistibly sweet. It’s a staple in Vietnamese kitchens, showing up in everything from Vietnamese iced coffee and egg coffee to even savory dishes like Bun Thit Nuong (grilled pork rice noodle salad).
  • Coconut Milk – For that creamy, tropical flavor that makes every bite taste like home.
  • Vanilla Sugar or Vanilla Extract – Just a touch of vanilla lifts the entire flavor profile, making the cake even more fragrant and inviting.
  • Tapioca Starch – This little addition helps bind everything together while keeping the cake’s signature chewy texture.
  • Melted Butter – It’s all about that buttery richness that makes the cake feel extra indulgent.
  • Shredded Coconut (Optional, but I’d never skip it!) – A handful of coconut meat adds lovely texture and an extra layer of coconut flavor that pairs so well with cassava.
  • Salt – Just a pinch to balance the sweetness and bring all the flavors together.

Instructions

Step 1: Prepare the Batter

  • Thaw the frozen cassava and squeeze out excess water if needed. In a large bowl, mix cassava, condensed milk, coconut milk, tapioca starch, melted butter, salt, and vanilla. Stir in shredded coconut.
  • Let the batter rest for 15–30 minutes while preheating the oven to 375°F (190°C).

Step 2: Bake

  • Grease a nonstick pan with butter and pour in the batter. Bake on the lowest oven rack for 50–60 minutes, until the edges are golden and a toothpick inserted in the center comes out clean.

Step 3: Broil for Color

  • Move the pan to the top rack, increase the oven to 400°F (205°C), and broil for about 5 minutes until the top is golden. Watch closely to avoid burning.

Step 4: Cool and Cut

  • Let the cake cool completely. Grease a knife with butter and cut into pieces before serving.

Expert Tips

Pan choice matters: I like using a large square or rectangular pan for Bánh Khoai Mì Nướng. The thinner the batter spreads, the crispier that golden crust will be—my favorite part!

Storing it right: This cake stays good at room temperature for about a day. For longer storage, pop it in the fridge (up to 3 days) or the freezer (up to 3 months). Just warm it up before serving—it tastes almost like it’s fresh out of the oven.

Vegan-friendly swaps: Want a plant-based version? Use vegan condensed milk and vegan butter. It’s just as rich and coconutty!

Serving idea: Enjoy it with a classic Vietnamese drink like egg coffee, salted coffee, corn milk, or avocado smoothie.

Equipment

  • 1 large square or rectangular pan (mine measures 16" x 12" / 41 x 31 cm)

Ingredients
  

  • 2 pound frozen grated Cassava (900g – 1kg)
  • 1 can sweetened condensed milk (14oz or 400g)
  • 1 can coconut milk (13.5oz or 400ml)
  • 2 cup shredded coconut meat (160-170g)
  • 1 sachet vanilla sugar (or 2 tsp vanilla extract)
  • 2 tbsp tapioca starch
  • 2 tbsp melted butter (30g)
  • ¼ tsp salt

Instructions
 

Prepare the cassava batter:

  • Start by thawing the frozen cassava. If your cassava has a high water content, you can gently squeeze out the extra moisture.
  • In a large bowl, add the grated cassava, condensed milk, coconut milk, tapioca starch, melted butter, salt, and vanilla sugar. Combine thoroughly all ingredients. Add the coconut meat and mix well.
  • Let the batter sit for 15-30 minutes. During waiting, preheat your oven to 375°F (190°C).

Bake the cassava cake:

  • Grease a nonstick pan with butter. Pour the batter into the pan.
  • Bake the cassava cake for about 50 – 60 minutes on the lowest oven rack.
  • After 50 minutes, check if the edges of the cake have turned golden brown. To check if it's fully cooked, insert a wooden toothpick into the center of the cake. If it comes out clean, the cake is ready.
  • Now, move your cake to the top oven rack. Raise the oven temperature to 400°F (205°C) and broil for about 5 minutes, or until the center of the cake get a golden hue. Keep a close eye on this period.

Serve:

  • Once the cassava cake is done, let it cool completely.
  • Use a knife to cut the cake into parallelogram-shaped pieces. It would be a bit sticky so you could grease the knife with some butter before cutting.

Ich würde den gefrorenen Maniok bestellen. Kann ich den ein paar Tage noch im Gefrierfach lassen, bevor ich den verwerte?

Okay danke und dann hätte ich noch ein paar Fragen:
Muss man Maniokstärke verwenden oder geht auch einfache Speisestärke oder eine andere Stärke aus dem Supermarkt? Und wie lange lässt du den Kuchen abkühlen?

Daniel

Achso und kann ich auch Kokosraspeln anstatt geschreddertes Kokosfleisch verwenden?
