Ingredients

Smoothie Cube Ingredients:

¾ cup plain Greek yogurt I use Oikos Triple Zero plain Greek yogurt
1 tablespoon peanut butter Or other nut butter
2 tablespoons vanilla or unflavored protein powder (2 scoops) I like Designer Whey vanilla
4 ounces chopped, raw kale
1 banana Or about ½ cup frozen banana slices
2 ounces water more or less as needed

Smoothie Prep Ingredients:

½ cup milk (amount approximate) I like Fairlife Milk

Instructions

Add the yogurt, peanut butter, protein powder, kale, banana and water to a blender with a tamper. Alternatively, use a food processor. (This mixture will be very thick, especially if using frozen bananas.)
(Reference recipe notes: Smoothie Cube Blending Tips.)
If your blender has a smoothie setting, use it to blend. If not, blend on high until ingredients are mostly blended. It's ok if not all of the fruit or greens are pureed fully.
Pour into a silicone mold (such as an ice cube tray) and freeze for at least 4 hours.
Once frozen, store in an airtight container or bag.
To use the smoothie cubes, add desired number of cubes to a blender with preferred amount of milk.
For a very small smoothie, use 1-2 cubes and about ¼ cup milk. For a larger smoothie, use 3-4 cubes and ½ cup milk. Adjust the amount of smoothie cubes and milk to your preferences, using more cubes and less milk for a thicker smoothie and fewer cubes and more milk for a thinner smoothie.

Notes

Nutrition information is per smoothie cube, assuming each smoothie cube is about 1-½ ounces (the size of a medium-large ice cube).

Ingredient amounts: Ingredient amounts are variable and should be adjusted to your taste and texture preferences. Use this recipe as a base and adjust as needed. Use high-protein versions of the ingredients to increase the protein amount.

Smoothie Cube Blending tips: In my experience, the order that you add the ingredients matters. In general, add in the following order:

Creamy or liquid items first (such as the yogurt and peanut butter)
Leafy greens go next (the kale)
Frozen and hard to blend items on top (the fruit if frozen)

If the blender jams while running, use your blender's tamper (if it came with one) or pause blending and stir.

Because this mixture is very thick, a food processor would also work well.

Making the Smoothie Blending tips:

For very small smoothies, a smaller personal size blender works very well.
If your blender is struggling to blend the cubes, try adding only a few cubes at a time. This is especially helpful when making large batches of smoothie.
