Why You’ll Love This Recipe

This smoothie has quickly become one of my favorites to make. I love how it only takes 5 minutes to throw together, yet it feels like a fancy café treat every time. The natural sweetness from mango, pineapple, and banana makes it taste like dessert, without needing any added processed sugar. Plus, the blue spirulina gives it a fun and vibrant color—with zero fishy taste. It’s always a hit with kids too, especially when I let them paint the “clouds” on the glasses.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 medium banana, frozen in chunks
½ cup plain coconut yogurt, divided
½ cup unsweetened soy milk (or other plant milk)
½ cup frozen mango
½ cup frozen pineapple
2 teaspoons almond butter
1 teaspoon blue spirulina powder
¼ cup ice (optional, for extra iciness)
honey or maple syrup (optional, for added sweetness)

Directions

I start by cutting a banana into chunks and freezing it for at least 20 minutes, or overnight for convenience.
I use the back of a spoon to “paint” coconut yogurt clouds inside the smoothie glass using half of the yogurt.
Then, I add the remaining yogurt, frozen banana, mango, pineapple, soy milk, almond butter, blue spirulina, and ice into my blender.
I blend everything on high for 30 seconds to a minute until smooth. If it gets too thick, I’ll add a splash of water to thin it out.
Finally, I pour it into the prepared glass and enjoy immediately.

Variations

If I’m out of banana, I sometimes swap it with half a small ripe avocado for that same creamy texture.
Instead of coconut yogurt, I’ll use another plain plant-based or dairy yogurt.
Almond milk, oat milk, or even dairy milk works great in place of soy milk.
I’ve also made it using just mango or just pineapple depending on what I have in the freezer—it’s still delicious.
Peanut butter or sunflower seed butter works perfectly in place of almond butter. Or, I’ll skip it entirely when I want a lighter drink.

storage/reheating

This smoothie is best enjoyed fresh, but I’ve kept leftovers in the fridge for up to 24 hours and it still tasted great. I give it a quick stir before drinking. Freezing isn’t ideal though—it tends to lose its texture.

FAQs

What makes a smoothie blue?

The vibrant blue color comes from blue spirulina powder, a natural pigment derived from algae. It doesn’t have a strong flavor and blends beautifully into smoothies.

Does blue spirulina powder have a fishy taste?

Not at all. Blue spirulina is actually tasteless and odorless, unlike its green counterpart which can sometimes have a seaweed-like taste. It adds color without altering the flavor.

Can I make a blue smoothie without a banana?

Yes, I’ve made it with frozen avocado instead of banana for the same creamy consistency. The taste changes a bit, but it’s still delicious.

Can I prepare this smoothie in advance?

I prefer drinking it right after blending, but I’ve made it the night before and stored it in the fridge. Just give it a stir before drinking, and it’s good to go within 24 hours.

What does blue spirulina do for the body?

Blue spirulina is rich in antioxidants, vitamins, and minerals. I like using it because it may help with energy, immunity, and overall wellness—plus, it turns my smoothie into a visual treat.

Conclusion

This Blue Spirulina Smoothie isn’t just beautiful—it’s a nutritious, kid-approved, feel-good drink I keep coming back to. I love how quick it is to make, how easy it is to customize, and how fun it is to serve with its cloud-like yogurt swirls. Whether I’m making it for breakfast or an afternoon pick-me-up, it always hits the spot.
