Prepare the Coconut: Carefully create a small hole in the coconut to drain the coconut water into a bowl. Use a corkscrew wine opener for ease, ensuring the coconut remains intact. Once drained, slice the coconut open and chop the meat into small pieces, making sure to reserve any floating pieces for texture later.

Blend the Ingredients: In a blender, combine the chopped coconut meat, reserved fresh coconut water, 4 cups of water, sweetened condensed milk, evaporated milk, and pure vanilla extract. Blend on high for about 1-2 minutes until the mixture becomes smooth and creamy.

Strain the Mixture: Pour the blended mixture through a fine mesh strainer into a pitcher, straining out half while leaving some particles for texture.

Adjust the Consistency: Add the remaining 4 cups of water to your pitcher, stirring gently until well combined. Taste and adjust sweetness if necessary.

Serve the Coconut Cooler: Fill a glass with ice to keep your Coconut Cooler chilled and refreshing. Pour the mixture over the ice.

Garnish and Enjoy: Enhance your Coconut Cooler by garnishing with coconut slices, fresh mint leaves, a sprinkle of cinnamon, or small pineapple wedges.
