Heat 3/4 cup water with 1/4 cup maple syrup. Bring to a simmer, remove from heat then add 1 cup cocoa powder and 1 Tablespoon vanilla. Whisk until well mixed. Add a spoonful to milk or use to top cookies or other desserts. Store in the refrigerator. If you prefer your syrup to be very sweet you will want to add more maple syrup.
