Can we get rid of eaten haram food by throwing up?

My aunt made a cake and bring it to our home today and i ate one part. I didnt asked if it was halal since she is a muslim as well so i tought it was ok to eat. The cake didnt had any odor or alcohol taste. But she said that she brought an already made dough. In the country i live in (France) pre made dough are always made with alcohol (exept ones that are sold in shops owned by muslims but i know she haven't brought it there). So knowing that i just consumed alcohol i tried to threw it up (took me a long time to do so since im not used to it lol). I did threw up in the end but im not sure if i got rid of it all or just one bit. So my question is that i saw that consuming haram food make your duaa be rejected for 40 days. Does it concern any one that does it or just ones that does it willingly ?
