This Iced Blue Spirulina Latte is one of those recipes that makes you smile before the first sip — the color alone is irresistible. It blends mild, ocean-like spirulina with creamy milk and a touch of vanilla and sweetener for a balanced, lightly sweet iced latte that's as Instagram-friendly as it is delicious.

It’s quick to make: bloom the spirulina, stir it into cold milk, and whip up a silky coconut vanilla foam to spoon on top. Perfect for a bright morning pick-me-up or a chilled afternoon treat, and easy to adapt to your preferred milk and sweetener.

Directions

  1. 1
    Blue spirulina whisked into warm water

    Heat 2 tablespoons warm (not boiling) water and whisk in 2 teaspoons blue spirulina powder until fully dissolved and smooth.

  2. 2
    Sweetener and vanilla stirred into blue spirulina

    Stir in 1 tablespoon of the honey or agave and 1/2 teaspoon vanilla into the spirulina mixture; add a pinch of fine sea salt and whisk to combine.

  3. 3
    Tall glasses filled with ice cubes

    Fill two tall glasses with about 3/4 cup ice each (total 1 1/2 cups).

  4. 4
    Milk poured into blue spirulina over ice

    Divide the spirulina mixture between the glasses, then pour 1 cup milk into each glass, stirring gently to combine so the color stays vibrant.

  5. 5
    Coconut vanilla foam shaken in a jar

    For the coconut vanilla foam: pour chilled 1/2 cup full-fat canned coconut milk into a jar, add 1/2 tablespoon sweetener and 1/2 teaspoon vanilla, secure the lid and shake vigorously for 30–60 seconds until frothy. Alternatively, whisk or use a handheld frother.

  6. 6
    Coconut foam spooned over blue spirulina lattes

    Spoon the coconut foam over each latte and sprinkle with toasted shredded coconut or an edible flower for garnish.

  7. 7
    Finished blue spirulina lattes served with straws

    Serve immediately with a straw and give it a gentle stir before sipping to enjoy the layered flavor.

Ingredients

  • blue spirulina powder:2 tsp
  • warm water (to bloom spirulina):2 tbsp
  • milk of choice (almond, oat, or dairy):2 cups
  • full-fat canned coconut milk, chilled:1/2 cup
  • honey or agave syrup:2 tbsp
  • vanilla extract:1 tsp
  • ice cubes:1 1/2 cups
  • toasted shredded coconut (garnish):2 tbsp
  • fine sea salt (pinch):1 tsp

Tips & Notes

  • If you prefer a vegan version, use agave or maple syrup instead of honey and a plant milk you enjoy.
  • Blooming spirulina in warm water helps it dissolve evenly and prevents clumps in the cold milk.
  • Chill the canned coconut milk thoroughly (overnight if possible) so the cream separates and froths more easily for a thick foam.
  • Adjust sweetness to taste — spirulina can taste grassy to some, so start with less sweetener and add more if needed.
