Add the frozen strawberries, white rum, and pineapple juice to your blender and blend until the mixture is completely smooth, forming the strawberry base layer.
Distribute the strawberry mixture evenly into two glasses and rinse your blender to prepare for the next layer.
Combine frozen pineapple chunks, white rum, pineapple juice, and cream of coconut in the blender, blending thoroughly until creamy and smooth, creating the pineapple coconut layer.
Gently pour or spoon this pineapple coconut blend on top of the strawberry layer in each glass to achieve a beautiful layered effect.
Top off your drinks with fresh pineapple wedges and strawberry garnishes as desired to add a colorful and tropical touch.
