Rinse out the blender. Place frozen avocados, banana, and 1 cup of vanilla almond milk in the blender and puree until smooth. Add more milk if texture is too thick.
Layer the two flavors into the popsicle molds. Insert the popsicle sticks, if it does not stay in place use a piece of tape to hold them into place. Freeze for at least 6 hours, or overnight.
Enjoy!
