That's basically what you'd be doing if you topped off your breakfast or snack with Dunkin' Donut's new Milky Way Hot Chocolate.
A collaboration with the Mars chocolate bar company, with 400 calories in a large you'd be closing in on the calories of 2 actual Milky Way bars.
Interestingly, you'd also be putting back 820mg of sodium - over half of what the National Sodium Policy statement recommended you should consume in a daytime.
The calories I understand, but who would have thought hot chocolate had so much salt?
