If I could get someone to make high calorie sugar laden cereal locally, I'd eat that too.
for high calories, I do
1/4 cup steel cut oats (170 cal)
1 cup blueberry yogurt (170 cal)
4 oz 2% milk (61 cal)
1 banana (100 cal)
mix everything but the banana the night before & eat it cold out of whatever container you put it in.
