Handmade donut café in Seongsu, crème brûlée donuts to go: Overdose

In short

Overdose Donut & Coffee Seongsu is a handmade donut café on Wangsimni-ro 10-gil near Ttukseom Station in Seoul, where the dough and cream are made in-house from early morning every day. The writer took home four Overdose donuts (Earl Grey, yuzu, crème brûlée and sweet potato castella), and the crème brûlée donut, with its crisply cracking sugar crust, made the biggest impression. With cream that isn't overly sweet, a chewy dough and a pretty, sturdy box, Overdose Donut & Coffee is a donut shop worth recommending for Seongsu dessert gifts.

What's the atmosphere at Overdose Donut & Coffee Seongsu like?

Overdose Donut & Coffee Seongsu isn't a colorful, candy-bright donut shop. It's a calm, upscale café with a dark gray brick exterior and a reddish-brown interior. I assumed a donut café would be all bright colors, but the mood was totally different ✨

The space is cozy and stylish, and the seats are nicely spaced out, so it's quieter than other Seongsu cafés 🤫 The owner and staff all greeted us so warmly and cheerfully that it put me in a great mood 😄

How does the crème brûlée donut taste?

The Overdose crème brûlée donut was personally the most memorable item of this visit 💯

The sugar on top is set thin and crisp, so it cracks with a snap when you press it lightly 😆 Inside is plenty of smooth, rich custard cream, so happiness bursts out in a single bite.

How does the sweet potato castella donut taste?

The Overdose sweet potato castella donut has a special shell with the soft, fluffy crumb of castella (Japanese-style sponge cake) 🍠

The sweet potato aroma is baked into the bread itself, and the sweet potato cream inside is sweet and thick. It tastes warm and nutty, like eating a roasted sweet potato, and it really calms the heart. If the other donuts are refined café desserts, this one feels warm and homey 😊

How does the yuzu donut taste?

The Overdose yuzu donut is filled with plenty of fresh yuzu (Korean citron) cream, so it isn't cloying 🍋 The tangy-sweet yuzu aroma balances the sweetness of the cream, so it tastes clean. If you eat it in the middle of a few donuts, it refreshes your mouth!

How does the Earl Grey donut taste?

The Overdose Earl Grey donut has a subtle black tea aroma running through all the cream ☕ The moment you bite in, it's fragrant with a slightly bitter aftertaste.

It's not just sweet, so I never got tired of it and enjoyed it to the last bite 😋 If you like black tea, definitely pick this one!

Overall, how were the donuts at Overdose Donut & Coffee?

Overall, the donuts at Overdose Donut & Coffee have a chewy shell of just the right thickness, and the cream brings out the natural aroma of each ingredient. They're not overly sweet, and I could really feel why this has been loved for so long among Seongsu bakeries 🙌

The takeout box is pretty and sturdy too, so it's perfect as a gift 🎁 If you're touring Seongsu desserts, definitely stop by!
