3-Ingredient Instant Hot Chocolate (Dairy-Free!)

I made this, but it tasted too watery and not sweet enough. I remade it again, but this time I basically doubled the recipe for one mug of hot chocolate: 4 tablespoons of coconut milk powder (I bought it on Amazon), 2 tablespoons of cocoa powder, 4 teaspoons of coconut sugar, and 1 teaspoon of cinnamon (I like more). I mixed it with coconut milk I microwaved in a mug for 1.5 minutes. It was a lot better.
