Refrigerate coconut milk overnight or for 4 hours to allow coconut cream to separate from water.
Place a ceramic, glass, or metal bowl in the freezer for 15 minutes before whipping the cream.
Open the can of coconut milk and only remove the solid white cream from the can and place into the bowl that was chilling in the freezer (you can save the liquid part and use it in your coffee, smoothies, cereal, or oatmeal).
Using an electric mixer (you may do this by hand, but it will take longer) whip the coconut milk solids for 5-10 minutes. Mix until peaks are able to form and hold its shape.
Add vanilla extra and agave. Mix until fully incorporated.
