Add strawberries and maple syrup (if needed) into a blender. Blend until smooth, scraping down the sides of the blender as needed.
Pour strawberry mixture into a large mixing bowl. Add chia seeds. Whisk until just incorporated.
Pour the strawberry chia seed mixture into a popsicle mold. Make sure to leave about ¼” of space at the top of the mold to allow the popsicles to expand in the freezer. Insert popsicle sticks into the mold, or follow instructions for your mold.
Freeze for 6-8 hours.
Remove from freezer. Allow to thaw for a few minutes. If needed, run popsicle mold under a bit of lukewarm water to help the popsicles loosen.
Place the popsicle mold on a flat surface and wiggle the popsicles out. Enjoy!
