A gentle, sweet scent of vanilla wafted through the air, and I could feel the warmth gradually spreading from the mug. The surface of the freshly made cake was moist, with a rich flavor and a springy texture, and I recall that the fluffy texture became more pronounced as I got closer to the bottom of the mug.

Overall, the texture was light and fluffy with a slightly chewy bite, and I enjoyed a lighter mouthfeel than that of typical steamed egg bread. The distinct sweetness of vanilla came through clearly, and the rich flavor of the egg complemented the sweetness of the vanilla.

Compared to the standard fluffy version, this one has a moister texture overall. Its appeal lies in its deep, rich flavor, enhanced by the tang and richness of cream cheese. The sweet aroma of vanilla blends perfectly with the cream cheese flavor, allowing me to fully enjoy this mild, cheesy steamed cake.
