How do i make cookies?!
Answers: with soda?
what?
yep. exactly right.
Uh, your question needs to be wording as a complete sentence for people to understand it. I'm guessing you want to make cookies with baking soda, vs. using baking powder, or both? Or do you want to make cookies using the beverage soda?
What kind of cookies do you want to make? What type of stuff do you like in your cookies? Oatmeal? White chips? Chocolate chips? What type of chocolate chips? Nuts? Which kind of nuts? Dried fruit? What kind of dried fruit? Otherwise no one can really help you.
Do you get it now? Explain yourself and your intentions and you might get better help and an actual answer that's really helpful.
