Add the crushed pineapple, coconut cream, white rum, granulated sugar, and ice cubes into the blender.
Secure the lid on the blender and blend on high speed for about 30-45 seconds until the mixture is smooth, thick, and frosty, with no visible chunks of ice.
Stop the blender and check the consistency; the drink should be creamy, with a glossy, slightly bubbly surface indicating proper blending.
Pour the blended Piña Colada into chilled glasses, ensuring an even distribution of the frosty mixture.
Garnish each glass with a pineapple wedge or maraschino cherry if desired, and serve immediately with a straw or cocktail umbrella.
