Chill two lowball or tumbler glasses in the freezer.

In a blender, combine frozen strawberries, 2 oz white rum, 1 oz lime juice, 1 oz simple syrup, and 1 cup crushed ice. Blend until smooth. Add more ice if needed for a thick slush.

Divide the strawberry mixture evenly into the bottom of the chilled glasses.

Rinse the blender pitcher thoroughly.

In the clean blender, combine cream of coconut, 2 oz white rum, 2 oz coconut rum, 1 oz lime juice, 0.5 oz simple syrup, and 1.5 cups crushed ice. Blend until smooth and creamy.

Carefully pour or spoon the coconut mixture over the strawberry layer to create a distinct two-toned look.

Garnish each glass with a fresh strawberry on the rim and a sprinkle of shredded coconut. Add a straw and serve immediately.
