Add the kefir, nut or seed butter, and hemp seeds to a blender.
Add the desired additional ingredients from the desired flavor combination.
Blend very smooth, starting on low and working up to very high.
Serve immediately.
Notes
You can store these for up to 6 hours in an airtight container or reusable pouch in the fridge. They will be slightly less thick and you may need to stir them slightly, but they store well.
Omit the hemp seeds if needed or desired.
Add 1/4-1/2 cup plain Greek yogurt or cottage cheese for additional protein.
Serve in a small open cup, a straw cup, or a reusable pouch.
Start the blender on low and work up to high. Blend for 30-60 seconds to allow ample time for the mixture to become super smooth.
Sweeten to taste with a little maple syrup or honey (for kids over 1).
If you are unable to find kefir, use half milk and half plain yogurt instead.
I like to freeze fresh raw cauliflower to use in this recipe. Frozen cauliflower from the store is meant to be cooked.
Add 1/2 banana for additional creaminess in any of the smoothies.
