that not how it works. that's not how any of this works.

the aerobics build up muscle that will always be burning calories by merely existing. a donut here and there won't make a negligible difference, as long as the weekly aerobic activity level is maintained.

Muscles don’t burn that much calories, only like 13 kcal/kg/day. So if I suddenly gained 10 kg of muscle, I could theoretically burn half a donut per day. Plus the extra calories spent moving those 10 kg of muscle around. But it’s not a free meal.

Eeeh. Exercise doesn't spend enough energy for high calories foods to be worth it. If you want to lose weight that is. A donut is a lot of exercise and muscle building leads to a small but not sufficient calorie spend. The majority of calorie spend still comes from the organs and general body maintenance

Meh..not as much as you hope or expect. There is a popular channel on youtube @ErikTheElectric who does these huge food challenges, but also tons of cardio like marathons and 100-mile bike rides, to try to offset it. He weighs 170. At his height I weigh 15 lbs less, simply from eating less despite doing much less cardio than him. The body is very good at increasing its efficiency in response to exercise. You will be working your ass off doing cardio, but the weight just not budging much beyond water fluctuations. Many people report this. They will do 20-thousand steps and stop losing weight after a few days.

As for muscle, a pound only burns 11 calories/day. You'd have to gain 20 lbs of muscle, basically become a bodybuilder, just to offset a KitKat. The math is pretty depressing.
