Directions:

Combine cocoa powder, sugar, salt, and heavy cream in a mixing bowl or bowl of a stand mixer. Beat, using the whisk attachment, electric beaters, or a whisk, until dry ingredients are evenly incorporated and cream forms soft peaks.

Combine hot coffee, Frangelico, and simple syrup in a prewarmed mug. (You can prewarm it by pouring hot water into it, letting it stand for 1 minute, then draining.)

Using a spoon, dollop whipped cream on top of coffee and top with a dusting of cocoa powder. Serve right away. (Note that you may have more whipped cream than the mug can accommodate; feel free to add more as you drink, or use some for the next round.)
