Direct answer: Chinese pumpkin cakes, or nan gua bing, turn chewy rather than sticky when dry cooked pumpkin is mixed with glutinous rice flour gradually. Shape the soft dough around red bean paste, flatten to 1/2 inch/1.25 cm, then pan-fry over medium-low heat for 3 to 4 minutes per side until golden and fully hot inside.
Key takeaways
- Steam pumpkin instead of boiling it so the puree absorbs less water.
- Add glutinous rice flour by dough feel because pumpkin moisture varies.
- Cool the puree until warm before kneading.
- Seal filling completely and keep every cake the same thickness.
- Cook over medium-low heat so the center softens before the outside burns.
What is nan gua bing?
Nan gua bing means pumpkin cake or pumpkin pancake in Mandarin. This home-style sweet combines cooked pumpkin with glutinous rice flour to make a soft orange dough. Some versions are plain; others surround sweet red bean paste and may be coated with sesame or breadcrumbs.
Despite the English word cake, it is not a flour cake with a crumb. The cooked texture is tender and pleasantly chewy, similar to mochi but softer because pumpkin supplies moisture and fiber.
Ingredients for eight cakes
- 12 ounces/340 g peeled seeded kabocha or butternut squash, cut in 1-inch/2.5-cm cubes
- 1 1/4 to 1 1/2 cups/160 to 190 g glutinous rice flour
- 2 tablespoons/25 g sugar
- 1/8 teaspoon salt
- 5 ounces/140 g smooth red bean paste
- 2 tablespoons white sesame seeds, optional
- 2 tablespoons neutral oil for frying
Allow 20 minutes preparation, 15 minutes steaming, 15 minutes shaping and 8 minutes frying per batch. Glutinous rice flour is also labeled sweet rice flour; ordinary rice flour cannot replace it because it does not create the same flexible dough.
Step 1: steam the pumpkin
Set pumpkin cubes in a shallow heatproof plate and steam over steadily boiling water for 12 to 15 minutes. A fork should enter without resistance. Drain any liquid collected on the plate.
Boiling works only if the pumpkin is drained and dried well, but steaming gives more predictable dough. Roast at 375 F/190 C for 25 to 35 minutes as another dry option.
Step 2: make a smooth puree
Weigh 250 g cooked pumpkin into a bowl. Mash while hot with sugar and salt until no firm pieces remain. Let it cool for 10 minutes until warm, not steaming.
Large fibers or lumps weaken the dough around the filling. For very fibrous squash, press the puree through a sieve or use a potato ricer.
Step 3: add flour gradually
Stir in 160 g glutinous rice flour. When a shaggy dough forms, knead gently by hand. Add more flour 1 tablespoon/8 g at a time until the dough is soft, smooth and barely tacky.
Do not chase a rigid measurement. Watery pumpkin needs more flour, while dry kabocha needs less. Stop when a rolled ball holds its shape without sticking heavily to your palm.
Step 4: divide dough and filling
Roll red bean paste into eight balls of about 17 g. Divide pumpkin dough into eight equal pieces, roughly 50 to 55 g each. Keep both covered with a damp towel so their surfaces do not crust.
Commercial paste varies in softness. Chill it for 20 minutes if too sticky to portion, but do not freeze solid.
Step 5: fill and shape
Flatten one dough piece into a 3-inch/7.5-cm disk with slightly thinner edges. Put filling in the center, gather the edges, pinch closed and roll gently. Flatten seam-side down to 1/2 inch/1.25 cm thick.
Press both faces lightly into sesame seeds if using. Patch any crack with a small piece of dough; exposed filling can scorch and leak.
Step 6: pan-fry slowly
Heat 1 tablespoon oil in a nonstick or well-seasoned skillet over medium-low heat. Add four cakes with space between them. Cook for 3 to 4 minutes per side until golden.
Add 1 tablespoon water, cover for 1 minute, then uncover and let the surface dry for 30 seconds. This brief steam helps the center cook without making the exterior oily. Repeat with remaining cakes.
How to know they are done
A cooked cake feels flexible rather than pasty when pressed with a spatula, and the center is hot. If using an instant-read thermometer, aim for at least 165 F/74 C in the filling. The orange shell should be uniformly soft with no pale raw-flour line.
Let cakes rest 5 minutes before eating. Glutinous rice dough is extremely hot and sticky straight from the pan.
Substitutions
Plain cakes
Omit filling and shape each portion slightly thinner. Pan-fry about 3 minutes per side.
Black sesame filling
Use a firm commercial black sesame paste in the same weight. Chill it before shaping if soft.
Breadcrumb coating
Replace sesame with fine dry breadcrumbs for a crisp shell. Keep heat low because crumbs brown quickly.
Different squash
Kabocha gives strong flavor and needs less flour. Butternut works well; watery carving pumpkin may require much more flour and taste mild.
Common mistakes
The dough sticks everywhere
The puree is too wet or still hot. Cool it and knead in flour one spoonful at a time.
The cakes crack around the edge
The dough is too dry or was left uncovered. Knead in 1 teaspoon water and keep portions covered.
The exterior burns before the center cooks
Heat is too high or cakes are too thick. Use medium-low heat, equal thickness and the brief covered steam.
The cakes turn tough
Too much flour diluted the pumpkin. Add flour only until the dough is manageable, not firm like bread dough.
Filling leaks
The wrapper is uneven or seam was not sealed. Thin the edges, keep the center thicker and pinch completely.
Food safety and storage
Rinse the whole squash under running water before cutting so the knife does not carry surface dirt inward. Use a stable board and keep fingers clear of the hard skin. Do not taste raw glutinous rice dough.
Refrigerate cooked cakes within 2 hours at 40 F/4 C or below and use within 3 to 4 days. Reheat covered in a skillet with a teaspoon of water until hot throughout. Freeze shaped uncooked cakes separately for 1 month; thaw in the refrigerator before frying.

FAQ
Is glutinous rice flour gluten-free?
Pure glutinous rice flour contains no wheat gluten despite its name, but check packaging and other ingredients for cross-contact if cooking for someone with celiac disease.
Can I air-fry nan gua bing?
Yes, brush lightly with oil and air-fry at 350 F/175 C for about 10 to 12 minutes, turning halfway. The crust will be drier than pan-fried cakes.
Can I use canned pumpkin?
Use plain pumpkin puree, not pie filling. Cook it in a dry skillet for several minutes to remove water, then add flour gradually.
Why are my cakes mushy inside?
They are too thick, undercooked or made with very wet puree. Flatten evenly and use the covered-steam step.
Are these best hot or cold?
Serve warm after a 5-minute rest. Refrigeration firms the starch, so chilled leftovers should be reheated.
Conclusion
Chewy Chinese pumpkin cakes depend on controlling pumpkin moisture and adding sweet rice flour by feel. Shape even wrappers, seal the red bean filling and fry gently until both surfaces are golden and the center is hot. The finished nan gua bing should taste clearly of pumpkin, with a soft flexible shell rather than a heavy floury one.
