I would like to recommend a Taiwanese street desserts and bubble tea shop, the name is called “ISLACAKE_MADRID”
The only Taiwanese wheel cakes shop in Madrid. I usually come to this place at least twice a week. If you are in Madrid, you should definitely try Taiwanese wheel cakes and bubble tea here. The filling of wheel cakes has around 20 different flavors, you can choice sweet or salty.
All the wheel cakes are made in the moment, so you will need to wait around 20 minutes, but it is definitely worth it.
Here is the link on Google maps:
