How does the crème brûlée donut taste?

I got my donuts to go at Overdose Donut & Coffee. They come in pretty packaging, so they'd make a nice gift too.

I started with the crème brûlée donut.

The surface has a thin sugar coating that cracks slightly when you bite in, and underneath is a soft donut, so the contrast in textures is really clear.

It's packed with cream, but it isn't heavy and spreads softly, so it's easy to eat. The sweetness isn't overdone and there's a nutty richness too, so you keep going without feeling weighed down. That was the moment I understood why people call it a top Seongsu donut spot, and anyone who loves desserts will like this style.

How rich is the Rich Valrhona chocolate donut?

The Rich Valrhona chocolate donut is all about deep chocolate flavor. From the first bite the chocolate aroma burst out and filled my mouth.

The cream is chocolate-based too, so the flavor has depth, and the sweet-bitter balance works well. The donut itself is soft to chew and goes nicely with the cream inside, so it feels like a well-finished dessert. I'd especially recommend it to chocolate dessert lovers among Seongsu cafés.

Jeju matcha & salt caramel donut: the flavor combo

The last one I tried, the Jeju matcha & salt caramel donut, impressed me with how well its three flavors blend. The bitter matcha aroma comes first, then the caramel's sweetness follows, so you feel layers of flavor. A touch of salt on top keeps the sweetness clean.

The donut is chewy yet soft, which makes it fun to eat, and the clean aftertaste keeps you reaching for more. It's rare to find this combo done so well among Seongsu bakeries, so I was extra satisfied.

Overdose Donut & Coffee Seongsu struck me as a place with high dessert quality even among Seongsu cafés. It isn't just a good-looking space for photos; you can really enjoy a proper Seongsu dessert here, and the title of top Seongsu donut spot suits it well.
