Prepare Ingredients: Peel and dice fresh pineapple if not using frozen. Squeeze fresh oranges to get 1 cup of juice.
Blend Everything: In a blender, combine pineapple chunks, orange juice, crushed ice, ground cinnamon, nutmeg, cardamom (optional), sweetener, and coconut milk. Blend until smooth and frothy.
Adjust Consistency: If it’s too thick, add a splash of coconut milk or orange juice. If it’s too thin, add more crushed ice.
Serve: Pour the frappe into a tall glass. Top with whipped cream, a sprinkle of cinnamon, and garnish with a fresh pineapple slice or orange zest.
Enjoy: Serve immediately with a straw and sip away!
