Easy Sweet Potato Ang Ku Kueh (Red Tortoise Cake) Recipe
June 26, 2026
Ang Ku Kueh (Red Tortoise Cake) is a traditional Southeast Asian pastry made from a soft, chewy glutinous rice skin wrapped around a sweet mung bean paste.
Made from soft, chewy dough wrapped around sweet mung bean paste, it comes in little tortoise-shaped cakes.
Traditionally prepared for auspicious occasions like birthdays, newborn first-month celebration (moon yit), or for just everyday tea time.
In Chinese culture, red represents prosperity and tortoises represent longevity.
The ingredients are:
Glutinous rice flour
Sweet potato
Split mung beans
Sugar
Salt
and water (of course!)
Step 1: Wash and soak split mung beans overnight.
Step 2: Drain off the water, rinse, and add mung beans into a medium-sized pot.
Add water to just cover the beans.
Step 3: Add knotted pandan leaves.
Step 4: Cook mung beans until soft and mushy.
Step 5: Using a stick blender, blend till smooth
Step 6: Add sugar and cook until the paste thickens and is able to hold shape
Step 7: Set aside to cool
Peel and wash the sweet potato, then steam until soft.
Mash and sieve.
Leave them to cool down.
Note: Why did I mash and sieve the soft sweet potatoes?
My homegrown Japanese sweet potatoes were left for a bit too long in the ground; they aged a bit and have fibres.
Step 2: Add glutinous rice flour, sugar, and oil into the cool mashed sweet potato and mix into a soft dough.
Step 3: Add red food colouring (if using orange sweet potato, then omit this step), mix to form a homogenous red/ pink dough.
Step 4: Cover the dough with cling film or a bowl (to avoid the dough from drying out)
Step 1: Weigh 10g of dough and 10g of mung bean paste.
Roll into balls.
Step 2: Flatten the dough and place the mung bean in the middle.
Step 3: Wrap to enclose the mung bean paste
Step 4: Lightly dust your ang ku kueh mould with glutinous rice flour.
Step 5: Press the stuffed ball firmly into the mould, then whack the side against the table to pop it out
Step 6: Brush the cut up banana leaves with oil.
Step 7: Place the ang ku kueh on the banana leaves
Step 8: Steam for 10 minutes
Step 9: Remove from steamer and brush with oil for that signature glossy shine.
Just like Onde-onde (another Malaysian favourite kuih), mashed sweet potato is added to make the skin soft.
2) Steamer lid captures too much moisture. Use a bamboo steamer instead.
If refrigerating, re-steam for 3 minutes.
If kept in the freezer, re-steam for 8 to 10 minutes.
Why Angku??? Angku or Tortoise Cakes... Tortoise represents longevity... and the colour Red represents Good Luck... wonderful tradition to celebrate and bless the baby ...
And I still have some leftover split mung beans from last week (lap chup).... so this week Sweet Saturday ~ I am sharing with you...Angku
Add food colouring to water. Combine the mashed sweet potatoes with glutinous rice flour. Knead. Add water bit by bit until a smooth dough is achieved.
Take a bit of the dough... maybe slightly bigger than the size of the rolled-up split mung beans above... Flatten into a disc on your palm... add the mung beans ball ... wrap the ball with the dough.
Make sure that the split beans ball is fully enclosed. Roll gently to smooth.
Prepare steamer.
Cut up banana leaves and lightly oiled it. Place the uncooked angku in the steamer and steam for 10 minutes. Once it is cooked... lightly oil the angku surface (to prevent it from sticking to one another!!)... enjoy...
