These elderberry smoothie cubes start with blueberries, blackberries and elderberry syrup blended into a deep berry puree, then frozen. Toss a few into any smoothie for rich berry flavor. Prep once, and they are ready for weeks of busy mornings.
Place the blueberries, blackberries, elderberry syrup, vitamin D drops and olive leaf complex in a blender and blend until smooth.
Pour into two standard 16-well ice cube trays and freeze until firm enough to pop out.
Transfer the cubes to an airtight, freezer-safe container until ready to use.
To use, add the cubes to your favorite smoothie.
Notes
Berry Swaps: Strawberries, raspberries or any other berries can replace the blueberries and blackberries. Fresh or frozen both work; let frozen berries thaw slightly so they blend easily.
Elderberry Syrup: Homemade or store-bought elderberry syrup both work here.
Yield Tip: The puree should measure 4 cups. Add water if needed to reach it before filling the trays.
Freezing: Store the cubes in an airtight, freezer-safe container for up to 3 months. Add them to the blender straight from frozen.
