¾ cup unsweetened cocoa powder
¼ cup melted coconut oil
¼ cup to ½ cup pure maple syrup (or honey but I do find maple syrup yields a better consistency).
You can also stir in a splash of milk (dairy or plant based if you find the consistency to be too thick. A little goes a long way).
Add all ingredients to a small mixing bowl. Mix until everything comes together and you have a thick, rich frosting like consistency. Taste and adjust as needed, add a little more maple syrup/honey if not sweet enough or more cocoa powder if too runny. Spread onto cooled cupcakes, cookies, cakes, or sweet breads immediately. Although the frosting does stay moist after frosted, I find it does kind of stiffen up and becomes harder to spread after a little while so use right away.
