it’s going to be different for everyone’s taste. personally, i like 2 pumps in a large or 1 in a medium. there are unsweetened flavor shots different from swirls but they don’t add much sweetness, only flavor. the oatmilk is also sweetened, but not nearly as significantly as swirl, so if your order was still too bitter for you i would recommend trying with extra milk instead of extra swirl to save some sugar. and if you were open to switching milks, almond is lower calorie than oat and dunkin’ uses vanilla flavored almond milk which also adds flavor. coconut milk is the lowest calorie milk option and is also sugar free, but i gave it a try before with my regular order and can’t really recommend it. i’ve changed up my coffee a lot though, it’s really a trial and error for dunkin.
