I'm making a recipe and it just seems like so much for so little calories.. can someone help me verify the calorie content?

10 cal. - 2 tsp cocoa
65 cal. - dried milk 4 tbl
43 cal. - protien powder 2tbl (I tried to measure their "scoop" its muscle feast casein 22grams in 1 scoop and this is half of a scoop.. roughly)
32 cal. - sugar 2 tsp
10 cal. - 1 tsp flaxseed
0 - salt splash
------------------
160

It's confusing because online it says so many things like the US fda says there's 50 calories in 1 tablespoon of instant nonfat dried milk.. but the box here says 80 calories in 1/3 cup. which is more like 15 calories a tablespoon?

The data written on the box should be correct one.
