Seongsu donut café with corn streusel and yuzu donuts: Overdose

In short

Overdose Donut & Coffee Seongsu is a donut bakery in the Ttukseom Station food alley in Seongdong, Seoul, that makes handmade donuts every day at dawn and discards whatever isn't sold that day. The writer reserved a 4-donut box on Naver for takeout and tried the corn streusel, milk cream, coconut blueberry and yuzu cream donuts at home. The verdict: Overdose Donut & Coffee's cream isn't overly sweet, and the donuts are soft like regular bread with no greasy smell.

These aren't the kinds you see everywhere. I loved that there were so many unique donuts I'd never seen before.

There was also a really wide choice of coffee and tea. I grabbed my pre-ordered 4-donut box, went home and ate them there. Yum yum!

Looks perfect as a gift, right? But today they're going into my own belly~~

How do the four Overdose donuts taste?

Corn streusel donut

Corn streusel donut topped with roasted corn

The one I was most curious about: corn streusel! A roasted corn sits right in the center with corn cream inside. The cream itself isn't very sweet and the glaze adds the sweetness, so it goes well with the cream without being heavy. A not-too-strong consommé-ish note? The corn on top was soft too, so the texture never bothered me.

Milk cream donut

The second one, the milk cream donut, looked relatively simple, but

the milk cream had a slight powdered-milk taste, which was oddly welcome. 🤣🤣 A flavor that brings back memories!

Coconut blueberry donut

Third, coconut blueberry! I'd never had a dessert with this pairing so it felt fresh, and it went toooo well together! I thought the blueberry would be too strong, but the coconut held its own, haha. The balance between the two was the best.

Yuzu cream donut

Last, the yuzu cream! It's flavored with Goheung yuzu (Korean citrus), they say~

The yuzu freshness isn't overpowering like lemon, and the added sweetness makes it even more charming~!

I ate it the next day and it was still delicious~

Final verdict on Overdose Donut & Coffee Seongsu

Overall, the cream in Overdose's donuts isn't sweet, and the glaze on the bread adds the sweetness, so nothing was over the top! Also, since donuts are deep-fried, the bread itself often has an oily smell or dryness, but I didn't feel any of that with this Seongsu bakery's donuts, which I really liked. They were soft like ordinary bread.

This time I took the donuts to go because of time, but when I want a break from Seongsu's crowds, I'm planning to visit and have coffee and donuts in the shop!
