Place all ingredients in a blender, in the order listed.
Blend on medium-high speed for a few seconds until smooth and frothy.
Pour into glasses.
Garnish with whipped cream, toasted coconut flakes, and a pineapple wedge, and enjoy with a straw!
Notes
For the creamiest drink, use full-fat canned coconut milk. Stir it well before measuring so the thick coconut cream and water are fully combined. Carton coconut milk will also work, but the drink will be lighter and less rich.
Frozen pineapple concentrate. Minute Maid is discontinuing theirs, but there are other brands that make it! Old Orchard or Welch's works great. Most frozen juice concentrate comes in 12-ounce cans. Just use half of it (about 3⁄4 cup).
