3.5c flour, i would ballpark the oil rather high. a teaspoon will make a difference, let alone 15. try backing down to 1 or 2T oil and start with a little under 3c flour (2 3/4 perhaps) and see if you can work it from there.
my mom doesn't understand % so the bread (dough) recipe i made for her, is 3c high gluten flour and 1 1/3 water. 3T butter, 1t salt/sugar, ~1/2t yeast. works great, a good solid recipe to modify as needed/wanted
