Creamy Piña Coladas

2 cups unsweetened coconut-almond milk
2 cups chopped frozen pineapple
1/2 cup Malibu coconut rum, or to taste (I added about an eighth of a cup more to keep it more liquidy)
2 packets Splenda
1 tray ice

Combine ice, rum, milk, pineapple chunks and Splenda in blender and blend until smooth!
