What you will need
This recipe uses 8 simple ingredients that you can find at any grocery store:
- 1 tsp blue spirulina powder
- 1 cup coconut milk chilled
- 1 cup pineapple juice chilled
- 0.5 cup mango chunks frozen
- 2 tbsp agave syrup
- 1 tsp vanilla extract
- 1.5 cups ice cubes
- 2 tbsp shredded toasted coconut for garnish
Step by step instructions
Step 1: Blend the Mango Base
Combine the frozen mango chunks and pineapple juice in a blender. Blend until smooth and creamy. Pour evenly into the bottom of two large clear glasses and set aside.
Step 2: Mix the Blue Spirulina
In a small pitcher or bowl whisk the blue spirulina powder into the chilled coconut milk until fully dissolved and the color is evenly distributed throughout with no visible clumps.
Step 3: Sweeten the Coconut Mixture
Stir the agave syrup and vanilla extract into the blue coconut milk mixture. Taste and adjust sweetness as needed. The mixture should be mildly sweet to balance the tropical fruit base.
Step 4: Add Ice and Layer
Place ice cubes carefully on top of the mango layer in each glass. Pour the blue spirulina coconut mixture slowly over the ice using a spoon to preserve the layered effect.
Step 5: Garnish and Serve
Sprinkle toasted shredded coconut on top of each drink. Serve with a wide straw and encourage guests to stir before drinking to enjoy the swirling color effect.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- blue spirulina powder → butterfly pea flower tea for a similar vivid blue color
- coconut milk → oat milk for a lighter lower fat version
- frozen mango chunks → frozen peach slices for a different tropical flavor profile
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Using too much blue spirulina which creates an overwhelmingly green or teal color instead of a bright ocean blue
- Pouring the coconut mixture too fast which destroys the layered visual effect before serving
- Skipping the chilling step which results in a watery drink that dilutes quickly once ice is added
