In the 1970’s and 1980’s there were several books the either had characters that did it or promoted it.
Why is there no cooking tray in my new car’s engine bay?
Is it dangerous? (It would be less physically dangerous if there was a specific spot for it.)
What you can do safely is get a pack of cookie dough, wait till it’s summer time(hotter the better), be in Texas, Arizona or similar state, put cookie dough on pan and leave on your dash board, go to work.
When you get out of work you’ll have fresh baked cookies and your car will smell amazing!
One of my co workers at Disney did this, I’ve never tried it but every time I walked past their car with the cookie pan in the windshield I thought it was brilliant.
