Place the unopened can of coconut milk in the fridge for 4 hours (or overnight). Chill your bowl and beaters or blender by putting them in the freezer for a few hours, too.
Take the can of coconut milk out of the fridge and turn it upside down (don't shake it!). Open the can, pour off the clear liquid, then add the solidified white coconut milk to the chilled bowl/blender.
Add honey and vanilla.
Mix on high speed for 5-10 minutes, or until the coconut milk forms a thick cream with soft peaks.
