Gyeranppang is a postwar Seoul invention, dated to the 1980s in Inha-gwa-ri (Inha University area, Incheon) where a vendor began baking cornbread batter with a whole egg on top to undercut the price of a full breakfast. It spread through Seoul's college and subway-station carts in the 1990s and is now most associated with Myeongdong and Hongdae winter streetscapes. Variants now include cheese, bacon, or sausage on top, but the no-frills egg-on-cornbread is still the canonical version.
An Inha University-area cart invention from 1980s Incheon — a vendor baked cornbread batter with a whole egg on top to undercut the price of breakfast. Mold has to be 200°C; lower and the yolk overcooks before the batter rises. The cornmeal is only ~15% of the flour, just enough to nudge the cake toward sweet-corn.
Held in a paper sleeve, the size of a small zucchini. The top is a glossy yolk dome surrounded by set white; underneath, the batter has risen into a sweet-corn-tinged cornbread. First bite breaks the yolk — it floods the cornbread crumb. The contrast is the whole point: salty-rich egg against sweetened wheat-corn cake. A good gyeranppang has a yolk that runs but isn't raw; an over-baked one tastes of dry corn muffin. Eat within ten minutes or the yolk firms.
The defining trick is timing the egg with the batter. Drop the egg in too early (before batter starts to climb) and the white sinks and rubberises; too late and the batter sets without integrating the egg. The cornmeal addition isn't traditional cornbread — it's only ~15% — and serves to lighten the wheat crumb and add the faint sweet-corn note that pairs with egg. Mold temperature must be 200°C: lower and the yolk overcooks before the batter rises.
Variations
Plain egg-on-cornbread is the original Incheon-Inha-area form; Myeongdong and Hongdae carts now sell cheese, bacon, and sausage versions; Busan adds a sliver of green chili; some upscale cafés run truffle-oil drizzle.

How it's made
5 steps · 15 min active + 10 min waiting
- 112 min
Whisk batter: 180g cake flour, 30g cornmeal, 1 tsp baking powder, 50g sugar, pinch salt, 1 egg, 180ml milk, 40g melted butter. Rest 10 minutes — should pour like thick cream.
- 25 min
Preheat the oval gyeranppang mold (or 6 mini loaf tins) to 200°C. Brush each cavity generously with butter; the cavity should hiss when batter hits.
Watch outThe rested batter should pour like thick cream — thinner and it won't climb up around the egg, thicker and it bakes dense.
- 33 min
Pour batter to fill each cavity 70%. Crack one whole egg directly on top of each — yolk centred, white pooled in the batter. Sprinkle a pinch of salt and a few drops of soy or a strip of bacon (optional cart variations).
Watch outGet the buttered mold hot enough that the batter hisses the instant it hits — a cold cavity means the yolk overcooks before the bread rises.
- 412 min
Bake 12 minutes at 200°C: batter rises around the egg, the white sets, the yolk is still glossy. Tap the cornbread edge — it should bounce back, not stick.
Watch outCrack the whole egg dead-centre so the yolk sits in the middle and the white pools into the batter — off-centre and the yolk cooks unevenly.

Brush tops with melted butter while hot for shine. Slip out of molds. Sold from carts in paper sleeves, eaten standing — yolk runs into the cornbread on first bite.
