I used to make a fresh smoothie every morning as a midmorning/ after breakfast snack. These smoothies contained mostly a lot of greens, some berries and a ”superfood” green powder,  such as wheatgrass powder. I don’t make a green smoothie every single day anymore #LifeOfAFoodBlogger. The main reason for that is that it can be too much work, especially when I’m recipe testing and my kitchen is already one big mess. Until I decided to make: smoothie cubes.

Of course, I can always make a quick smoothie with just a few ingredients, but when it comes to smoothies, I’m actually very picky. A smoothie needs to make sense. It needs to contain ingredients that would be impossible for me to eat in for example a salad (read: lots and lots of greens). I don’t like to stack my blender full with fruits as well, since I enjoy them eating just as they are, not blended. You get my point, right? I prefer my smoothies green, and super healthy!

As such my smoothies can contain quite a few ingredients, and this takes times. So when I don’t make smoothies a priority, it’s just not happening. It’s just too much of a hassle. The solution? Make ahead smoothie cubes.

Smoothie cubes?

The idea is actually pretty simple and it started with me freezing my ingredients for a single smoothie the night before. This worked ok, but then I still had all these jars and powders that I needed to open and add. I know…first world problems. But then I realized, why not blend it and freeze it? It’s pretty much the same idea.

How to make smoothie cubes?

All you have to do is combine all the ingredients (including the powders) you would like to add to your smoothie and blend those in a blender with just a tiny bit of liquid, such as water. Then spread this thick (banana ice cream like) mixture into cubes using a spatula or spoon. And freeze overnight.

That’s it! When you are ready to enjoy a quick smoothie, all the ingredients for this are waiting for you in the freezer. Just pop the smoothie cubes into your blender with some water or a plant-based milk, and blend. Rinse the blender and you are done.

Within minutes you will have the best smoothie, exactly how you want it, when you want it. It’s my new favorite! Delicious, and nourishing.

My smootie cubes recipe contains:

  • Cashews, a healthy fat source to make the smoothie creamy and rich
  • Ground flax, one of the richest sources of essential omega-3 fatty acids and for phytoestrogens
  • Banana, for a bit of sweetness
  • Berries, for antioxidants and to balance the flavor
  • Leafy greens, for all the health benefits that leafy greens have to offer
  • Cinnamon, for flavor and antioxidants
  • Vitals organic ”True Superfood” powder, because I think a good smoothie needs a high-quality green superfood powder

What is a green superfood powder?

You can go as crazy as you want with the ingredients of a green superfood powder. Sometimes I keep it simple and only add wheatgrass powder, but recently I have been loving the green powder by Vitals. It contains various types of vegetables, fruits, mushrooms, sprouts, greens and enzymes.

Why you should make smoothie cubes with a green superfood mix

  • The fruits and veggies in a green smoothie can already be extensive, so I think it’s great that I don’t have to open 5 or more jars to add a nice green superfood mix.
  • It is impossible to add all the ingredients to your smoothie that you find in a green superfood mix.
  • And when you don’t have a lot of smoothie ingredients at home, a green superfood mix will give that boost that might be lacking.

A few tips

  • The recipe I’m sharing with you today is one of my favorites, but feel free to customize and use the fruits and veggies you like. Have a favorite smoothie recipe, use that one!
  • To freeze your own favorite smoothie recipe into cubes I would suggest to use less liquid/water than you normally do. You really want to create a thick mixture.
  • Add a super food powder, this will bump up the nutritional value a lot.
  • If you don’t have a blender, you can use a food processor.
  • I tried to use plastic reusable ice cubes molds, but they broke when I tried to pop the cubes out of the mold. It’s better to use reusable silicone molds. I normally use one tray for 1-2 smoothies.

These easy to make smoothie cubes are a great trick to make a quick smoothie ahead. All you have to do is add the cubes to a blender with some liquid, and serve!


  • 1 cup berries, I use a mixture of blueberries and raspberries
  • 1 banana
  • 1 Medjool date (optional for extra sweetness)
  • ¼ cup (unsalted and unroasted) cashews
  • 1 tbsp ground flax
  • ½ tsp cinnamon
  • Large handful of greens, I use spinach
  • a few drops vanilla extract for flavor (optional)
  • 1 ½ scoops (10 gr) Vitals ”True Superfood” green powder
  • a small splash of almond- , oat- or soy milk to get the blender going, not too much (!)


Place all the ingredients in a (high-speed) blender. Add the green powder last, so it will not stick to the bottom. Blend together until you have a thick soft serve /ice cream like mixture. Be careful with the plant-based milk, don’t add too much.  If you don’t have a blender, you can use a food processor for this recipe.

Using a spatula or spoon, scoop out the smoothie mixture and spread it into the ice cube mold. Try to fill the cubes evenly. It helps to gently drop the mold on the kitchen counter so all bubbles and corners of the cubes will be filled.

Freeze overnight or for at least 4 hours. Until you are ready to use them.

When you are ready to make a smoothie, push the cubes out of the mold into a blender with 1 cup of water.  Add more water if you like your smoothie less thick. For a creamier smoothie use a plant-based milk, instead of water.  Blend until smooth, and enjoy!


This recipe should yield one big smoothie.

The cubes can be stores in the freezer for up to 1 month
