Some afternoons call for a quick piece of fruit…and others call for a full-on mermaid moment! This mermaid smoothie bowl is a gorgeous color that just adds a little fun to your day. It gives all the tropical vibes in the comfort of your own home.
As a dietitian and run coach, I love this smoothie bowl as a way to get healthy carbs into your day that help fuel exercise. Plus, you can customize the toppings to boost the nutrients, or add protein powder if you’re looking for a more satiating smoothie bowl. This recipe is very flexible!
And of course, it’s also a great option for kids – my son *loves* the fun bright blue color because it’s so unexpected in a smoothie.

Ingredients
Here’s a photo of what you’ll need for the base of this recipe, which is very simple:

As you can see, the recipe uses blue spirulina. Spirulina is a blue-green algae that is a natural source of certain vitamins, minerals, and phytonutrients. Not only is it an easy way to add an extra boost of nutrition to a recipe, but this is what gives it the lovely blue color. (Don’t worry, it doesn’t have a strong taste when blended in with the fruit). I used this Incas by Asiya brand from Amazon. But you can use whatever brand you prefer (there are others online or you can often find them at a natural food or supplement shop).
Alternative Natural Colors
You can also experiment with other natural coloring products to create different color variations. These include:
- Butterfly pea flower powder – This is a powder of a flowering vine. It can create deep dark blue hues when added to food and drinks. Fun fact: the more acidic ingredients in your smoothie bowl (like pineapple), the more the color will shift from deep blue to purple or pink when using this powder. For example, if you made a lemon smoothie bowl, you might end up with a much brighter purple-pink color compared to a banana smoothie bowl.
- Pink pitaya powder – This comes from red dragonfruit, creating a vibrant pink color in your smoothie bowl.
- Purple sweet potato powder – Like it sounds, this comes from dried purple sweet potatoes. You can use a little bit to create a light lavender color, or use more to create a richer purple hue.
Additional Tips
Thick smoothie texture: To get that ultra-thick soft serve ice cream texture, make sure your fruit is frozen and use the absolute minimum amount of liquid possible. A high-quality mini food processor (recommended, as seen below) or blender will help with this as the motor is powerful enough to get through frozen fruit with minimal liquid. Using a lower-quality processor or blender may require more liquid and result in thinner consistency.

Storage: This is best enjoyed immediately. I don’t recommend storing for future use.
Variations: Feel free to get creative with the choices of fruit in here; frozen mango and frozen peaches are great options in place of the pineapple.
Adding protein: If you’re enjoying this as a meal or post-workout option, I recommend adding a scoop of protein powder to boost the protein content. If done, you’ll need to increase the liquid to account for the powder. Around ½ cup of milk is generally what I’ve found works when adding protein powder but it can vary based on the type of powder and how much liquid it absorbs. Just add it little by little as you’re blending.
Topping Suggestions
You can add whatever smoothie bowl toppings that you like. A few ideas:
- Sliced bananas
- Fresh blueberries
- Dragon fruit
- Chia seeds
- Hemp hearts
- Pumpkin seeds
- Granola
- Cacao nibs
- Chocolate chips
- Shredded coconut

Mermaid Smoothie Bowl
Ingredients
For the smoothie base:
- 2 cups frozen pineapple chunks
- 1 medium frozen banana
- ½ to 1 tsp blue spirulina (use ½ tsp for pastel blue or 1 tsp for deeper blue; see notes for other coloring options)
- 3 to 5 tablespoons milk (dairy or plant-based)
For the toppings (optional; use whatever you prefer):
- Kiwi, coconut, dragonfruit, hemp hearts, banana, berries, etc.
Instructions
- Add the pineapple, banana, spirulina, and 3 tablespoons of milk to the bowl of a mini food processor (recommended) or a blender cup (for use with a high-speed blender).
- Process on high, pausing to scrape down the sides as necessary. It may take a couple minutes to fully combine. If the processor or blender can’t work through the mixture, add an additional splash of milk. Only add just enough liquid to process so that the mixture stays thick and creamy, like soft serve ice cream.
- Spoon the smoothie base into two chilled bowls. Add whatever toppings you’d like and enjoy!
Notes
- Alternative coloring options include butterfly pea flower powder (deep blueish purple), pink pitaya powder (pink), or purple sweet potato powder (purple).
- To boost the protein content, you can add a scoop of protein powder. You’ll need to increase the liquid to account for the powder. Around ½ cup of milk is generally what I’ve found works when adding protein powder, but it can vary based on the type of powder and how much liquid it absorbs. Just add it little by little as you’re blending.
- This recipe makes two medium-sized smoothie bowls. For a large smoothie bowl, you can eat the entire recipe.
