Gather your ingredients on your countertop.

Blend the fresh spinach, bananas, Greek yogurt, sweetener, and milk on high speed for 1-2 minutes until smooth.

Taste the mixture and adjust sweetness if necessary by blending more honey or syrup.

Pour the smoothie mixture into popsicle molds, leaving space at the top.

Insert sticks into the molds if applicable, or cover with foil and poke sticks through.

Freeze the molds for at least 4 hours until solid.

Run warm water over the molds to release the popsicles before serving.
