Here’s the question everyone asks before they’ve even tried it: does the egg actually cook, or are you biting into a runny raw yolk wrapped in warm bread? It cooks. The white sets solid, baked right along with the batter around it, and the yolk lands somewhere between jammy and fully firm depending on how long you leave it in. Nobody is serving you a raw egg with a straight face.
Gyeranppang is a simple thing once you get past that worry — sweet, slightly cakey bread with a whole egg baked into the top, sold out of small tins at street stalls and college-area carts. This version uses a regular muffin tin, because almost nobody outside Korea owns the double-decker cart mold, and the muffin tin gets you 90% of the way there with none of the specialty equipment.

What gyeranppang actually is
Gyeranppang (계란빵) breaks down plainly: gyeran (계란) is egg, ppang (빵) is bread. It’s less sweet than most Korean street bread, closer to a savory muffin than a dessert, which is part of why it works as a breakfast-on-the-go item near universities and subway exits rather than strictly a winter treat like its cousins.
Ask around about where it started and you won’t get a clean answer. A few different neighborhoods and market alleys each have a claim to being first, and none of it is documented enough to settle — which is fairly normal for street food, where nobody was filing patents on a muffin tin idea. Treat any single “official origin” story you read online with some skepticism; this is one of those dishes that seems to have shown up in a few places around the same time.
Ingredients, and what to use instead
| Ingredient | Where to get it, or what to use instead |
|---|---|
| Flour, sugar, baking powder, salt | Standard pantry items. |
| Milk, 180 ml / 3/4 cup | Any milk works; oat or soy milk makes the batter dairy-free with barely a difference in taste. |
| Neutral oil or butter | Either works; butter adds a faint richness the street version usually doesn’t have. |
| Whole eggs, 6 | This is the one ingredient with no real substitute — it’s the entire point of the bread. Use the freshest eggs you have, since a fresh yolk holds its shape better sitting on wet batter. |
| Cart-style double mold | Not required. A standard 6-cup muffin tin or popover pan gets a very similar result — round instead of rectangular, same texture. |
| Cheese, ham, bacon | Optional, for a savory version. Add after the egg goes on, not before, so they don’t sink into the batter. |
Gyeranppang
Ingredients
Method
- Heat the oven to 180°C / 350°F. Grease a 6-cup muffin tin or popover pan well, including the rim — the batter climbs while baking and sticks if the rim is bare.
- Whisk the flour, sugar, baking powder and salt together in a bowl.
- In a separate bowl, whisk the batter egg, milk and oil until smooth, then pour into the dry ingredients and stir just until no dry flour remains. A few small lumps are fine.
- Fill each muffin cup about two-thirds full with batter.
- Crack one whole egg directly on top of the batter in each cup. Don’t stir it in.
- Scatter on any savory toppings now, if using.
- Bake 18 to 20 minutes, until the batter around the egg is set and lightly golden and the egg white is fully opaque. Check at 16 minutes if you want the yolk to stay soft.
- Let the tin sit 3 minutes before unmolding — the bread is fragile straight out of the oven and tears at the sides if rushed.
How to make it
- Heat the oven and grease the tin well, including the rim. The batter rises as it bakes and grabs onto any dry spot.
- Mix the dry ingredients, then whisk the wet ingredients separately before combining. Stop stirring once the flour disappears — a few lumps won’t hurt anything.
- Fill each cup two-thirds full. Any fuller and the egg pushes batter over the rim while baking.
- Crack a whole egg on top of each cup. Don’t stir it in — it’s meant to sit and bake as a distinct layer, which is what gives you that yolk-in-the-center look when you cut one open.
- Add savory toppings now, if using. Cheese melts into the top layer; ham and bacon bits settle in around the egg.
- Bake 18 to 20 minutes. This is the part that decides everything: 16 to 17 minutes gives you a soft, jammy yolk; 20 minutes gives you a fully set yolk that slices cleanly. Neither is wrong — it’s a matter of preference, and the white is fully cooked in both cases.
- Let it rest 3 minutes in the tin before running a knife around the edge and lifting each piece out.
Sweet or savory
The batter as written is only lightly sweet, which is why it splits easily in either direction. Leave it as-is and drizzle a little ketchup and mayonnaise over the top once it’s out of the oven — a genuinely common street-cart combination, not an invented gimmick. Or drop the sugar entirely, add shredded mozzarella and a few bits of ham before baking, and you get something closer to a savory breakfast muffin with an egg built in. Both are correct. Neither is the “real” version any more than the other.
Tips and storage
The most common failure is underbaking, since the batter looks done well before the egg white fully sets — always check the egg, not just the crust color. If the top browns too fast before the egg finishes, tent a piece of foil loosely over the tin for the last few minutes. Gyeranppang doesn’t keep well past the day it’s made; the egg turns rubbery in the fridge and the bread dries out. If you must store leftovers, wrap them individually and reheat gently in a 150°C / 300°F oven for about 5 minutes rather than microwaving, which makes the egg tough.
Common questions
Is the egg fully cooked in gyeranppang?
The white always cooks through completely in the oven. The yolk’s doneness depends on bake time — shorter for soft and jammy, a couple of minutes longer for fully set. Either way it’s safe and intentional, not undercooked.
Can I make gyeranppang savory instead of sweet?
Yes, and it’s common. Cut the sugar from the batter, add shredded cheese or ham before baking, and skip the ketchup drizzle in favor of a pinch of pepper or scallion on top.
Do I need a special pan?
No. A standard muffin tin or popover pan does the job. You’ll get a rounder shape instead of the cart’s rectangular one, but the texture and the egg-on-top structure come out the same.
Why did my egg sink into the batter instead of sitting on top?
Usually the batter was too thin, or the egg went on before the batter had a chance to set even slightly. If your batter looks more like pancake batter than muffin batter, add a tablespoon more flour next time. You can also give the tins two or three minutes in the oven before adding the egg, so the surface has already started to firm up.
Where to find it
Gyeranppang carts tend to cluster near university gates and busy subway exits rather than tourist markets, though you’ll still spot one in the wider street food alleys. Gwangjang Market’s street food stretch usually has a stall or two if you’d rather try the original before making your own. Pair it with bungeoppang if you want to compare Korea’s two most common winter street breads side by side — one has red bean, this one has an egg, and neither pretends to be dessert exactly.
