In a blender, combine unsweetened cocoa powder, your preferred milk, ripe bananas if using, a pinch of salt, and a sweetener. Blend on high for about 30-60 seconds until smooth.

Optional: Add peanut butter or melted chocolate chips to the mixture and blend for an additional 10-15 seconds.

Pour the mixture into popsicle molds or small cups, filling them about three-quarters full.

Insert popsicle sticks immediately, pushing them down gently.

Freeze for 4-6 hours or overnight until solid.

To release fudgsicles, run warm water over the mold for 15-20 seconds and gently pull out the fudgsicles.
