Add all latte ingredients to a blender and blend until smooth. Strain before pouring into serving glasses if any clumps remain. (You can also put it in a saucepan over medium heat and whisk.)
Spread coconut flakes out on a shallow plate.
Dip the outer rims of the serving glasses in melted chocolate, then roll them gently through the coconut flakes.
Divide the latte between the two serving glasses. Top with coconut whipped cream and crushed almonds, if desired.
Notes
I made the coconut whipped cream an optional topping (ie. not included in the nutrition info) so you could more easily make a lower calorie swap by using a fat free whipped topping or whatever you would like.
