If one is makpid on pas yisroel does that mean they have to be makpid on pas haba bkisnin, such as pretzels or cookies?
Answer:
The prohibition does extend to cookies, pastries, and so on. However, If the batter from which the cookies are prepared is liquidy, and does not resemble a bread-dough, some maintain that the the prohibition would not apply.

See Tosafos, Beitzah 16b; Rema, Yoreh De’ah 112:6; Biur Ha-Gra, loc. cit. 4; Chochmas Adam 65:7; concerning a liquidy batter, see Shach, Yoreh De’ah 112:18; Chelkas Binyanim 112:64 cites authorities who dispute the leniency of Shach, and rule that all forms of pas haba bekisnin fall under the prohibition of pas akum.
