Function aside, this mushroom hot cocoa also passed the flavor test. This mushroom hot cocoa is no exception. But I had to remind myself I was testing the best mushroom hot cocoa, so naturally, it should resemble the classic treat we’ve all come to know and love. So, while it earns top marks for an indulgent treat, it’s not necessarily the ‘best’ mushroom hot cocoa for every palate. It also makes this mushroom hot cocoa more calorically dense than the others on this list (roughly three to four times the number of calories).
