How to Make Fiber Smoothie Cubes
-
Mix the chia seeds with 2 cups of almond milk in a bowl. Stir well and let it sit for 10-15 minutes until it forms a gel-like consistency.
-
Blend the chia gel in a blender. Add in the remaining ingredients, including the hemp hearts, cacao powder, pitted medjool dates, vanilla extract, and a pinch of sea salt. Puree until the mixture is smooth, adding extra milk if necessary for easier blending.
-
Transfer the thick mixture into two standard, 16-well ice cube trays. It’s perfectly fine if the mixture slightly overflows the wells, as long as it doesn’t spill over the sides.
-
Freeze the trays overnight or until completely solid. Once frozen, pop the cubes out and store them in an airtight, freezer-safe container. Keep them in the freezer for up to 2 weeks, or longer in a deep freezer.
-
Blend your desired smoothie by adding 1 cup of liquid (like more almond milk) and 2 cups of leafy greens to a blender. Toss in 4 fiber cubes and blend until smooth. If you want it sweeter, you can always add a ripe banana or a drizzle of maple syrup to taste.
Optional: Top your smoothie with a sprinkle of hemp hearts for an extra boost!

Freezing Time: Freeze thoroughly: Ensure your cubes are completely frozen overnight for ease of popping them out later.

Fiber Smoothie Cubes Recipe FAQs
How do I choose ripe medjool dates?
Look for medjool dates that are soft to the touch and have a slightly wrinkled skin. They should feel plump, and you’ll want to avoid any that are overly sticky or have dark spots all over, as those may be past their prime. Always go for dates that smell sweet and natural!
How should I store leftover Fiber Smoothie Cubes?
After freezing, keep the fiber cubes in an airtight, freezer-safe container. They can last up to 2 weeks in the freezer, or a bit longer in a deep freezer without losing texture. Just make sure to always close the container tightly to prevent freezer burn.
Can I freeze these Fiber Smoothie Cubes for longer?
Absolutely! If you need to extend the storage time, you can keep the cubes in a deep freezer for up to 3 months. Just ensure they are properly sealed in an airtight container to preserve their quality.
What can I do if my mixture is too thick?
No worries! If your mixture turns out thicker than expected while blending, simply add more almond milk or water, a little at a time, until you achieve a smooth, pourable consistency. This is often the case with psyllium husk powder, which thickens the mixture, so don’t hesitate to adjust.
Are these cubes safe for pets?
While the ingredients in Fiber Smoothie Cubes are generally safe for humans, some ingredients like cacao can be harmful to pets. It’s best to keep these cubes for your consumption only and not share them with your furry friends.
What types of greens can I use with my smoothie cubes?
You can mix and match! Feel free to add any leafy greens like spinach, kale, or Swiss chard. I often go for baby spinach for its mild flavor, but the more the merrier, so explore your favorites and discover new combinations!
