Dirty bag, the value of the name, looks dirty, and after eating, hands and face are also dirty, so named "dirty bag".
It is now very popular a kind of Netflix food, in the major video apps have its traces, it is made of chocolate and flour, eat every mouthful of mellow and not greasy. The texture is very crunchy and the overall flavor has a light buttery creaminess as well as a rich cocoa aroma.Even though it was high in calories, I couldn't resist its temptation after all. I bought two dirty buns from a cake store that was having a special and ended up with gastrointestinal distress and diarrhea. I realized that it was on sale because the bread had expired.
So it is better to go to a regular cake store to buy it.
