Heat one cup of water until boiling.
Use a kettle or small saucepan.
Make sure it's fully boiling.
Pour sugar-free gelatin into your mixing bowl.
Add the boiling water slowly.
Whisk until completely dissolved.
This takes about 2 minutes.
Let the mixture cool for 5 minutes.
Add your unflavored protein powder.
Whisk thoroughly to avoid lumps.
Make sure it's well combined.
Pour in one cup of cold water.
Stir gently to combine everything.
The mixture should be smooth.
Pour into your refrigerator-safe container.
Cover with a lid. Refrigerate for at least 4 hours.
Overnight works even better.
